Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Depending on the type of the touch object, different controls or whether or not to perform the same control can be determined according to the current state of the mobile terminal 100 or an application program being executed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor includes a photo diode and a transistor (TR) mounted on a row and a column, and an electric signal, which changes according to the amount of light applied to the photo diode, . That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of light change, and thereby acquires position information of the object to be sensed.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and may be generated as one image as they are combined. Generally, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit by the stereoscopic processing unit. The stereoscopic processing unit receives a 3D image (an image at a reference time point and an image at an expansion point), sets a left image and a right image therefrom, or receives a 2D image and converts it into a left image and a right image.

2 is a conceptual diagram for explaining another example of the mobile terminal 200 according to the present invention.

As shown, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display portion 251. The deformable display portion 251 may be referred to as a " flexible display portion ". Here, the flexible display unit 251 may include both a general flexible display and an electronic paper (e-paper) and a combination thereof. In general, the mobile terminal 200 may include features of the mobile terminal 100 of Figures 1A-1C or similar features.

A typical flexible display is a sturdy display that is lightweight and does not break easily, such as paper, which is fabricated on a thin, flexible substrate that can bend, bend, fold, twist, or curl like a conventional flat panel display.

In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can change the information by using a twist ball or electrophoresis using a capsule.

In a state in which the flexible display portion 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display portion 251 is flat. In the first state, the display area may be a curved surface in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). As shown in the figure, the information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible display portion 251 may be placed in a bent state (e.g., a state in which the flexible display portion 251 is bent up or down or left or right) instead of a flat state in the first state. In this case, if an external force is applied to the flexible display portion 251, the flexible display portion 251 can be deformed into a flat state (or a less bent state) or a more bent state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 180 (see FIG. 1A) can perform the control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input in the first state as well as the second state.

Meanwhile, the mobile terminal 200 according to the present modification may be provided with a deformation sensing means for sensing deformation of the flexible display unit 251. [ The deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting means may be provided in the flexible display unit 251 or the case 201 to sense information related to the deformation of the flexible display unit 251. Here, the information related to the deformation may be the direction in which the flexible display portion 251 is deformed, the degree of deformation, the deformed position, the deformation time, and the acceleration at which the deformed flexible display portion 251 is restored, In addition, it may be various information detectable due to warping of the flexible display unit 251.

The control unit 180 may change the information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 that accommodates the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251.

In addition, the battery (not shown) included in the mobile terminal 200 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

The state change of the flexible display portion 251 is not limited to an external force. For example, when the flexible display unit 251 has the first state, it may be transformed to the second state by a command of the user or the application.

On the other hand, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the dimension that the user holds mainly in the hand. Such wearable devices include smart watch, smart glass, and HMD. Hereinafter, examples of a mobile terminal extended to a wearable device will be described.

The wearable device can be made to be able to exchange (or interlock) data with another mobile terminal 100. The short range communication module 114 can detect (or recognize) a wearable device capable of communicating with the mobile terminal 100. If the detected wearable device is a device authenticated to communicate with the mobile terminal 100, the control unit 180 may transmit at least a part of the data processed by the mobile terminal 100 to the wearable device 100 via the short- Lt; / RTI > Accordingly, the user can use the data processed by the mobile terminal 100 through the wearable device. For example, when a telephone is received in the mobile terminal 100, it is possible to perform a telephone conversation via the wearable device or to confirm the received message via the wearable device when a message is received in the mobile terminal 100 .

Here, the position of the mobile terminal 100 can be tracked using all the techniques capable of tracking the location as well as the GPS tracking technology. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal, and may include a GPS module and a Wi-Fi module as typical examples. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 115 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a Wi-Fi Positioning System (WPS) can be utilized to compensate the positioning of the GPS system.

The Wi-Fi Positioning System (WPS) is a wireless communication system that uses a Wi-Fi module included in the mobile terminal 100 and a wireless AP that transmits or receives a wireless signal with the Wi-Fi module, ), Which is a wireless local area network (WLAN) based positioning technology using Wi-Fi.

The WiFi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which certain wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP can transmit a location information request message to the Wi-Fi location server.

The Wi-Fi position location server extracts information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi location server through the mobile terminal 100 or may be transmitted from the wireless AP to the Wi-Fi location server.

The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. The information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, and the telephone number. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Thereafter, the Wi-Fi location server may extract (or analyze) location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.

As a method for extracting (or analyzing) the position information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

The landmark method is a method of measuring the position of a mobile terminal using a landmark transmitter that knows the location.

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

The extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi location server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may be connected to at least one wireless AP to obtain location information. At this time, the number of wireless APs required to acquire the location information of the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

1A, a short distance communication technology such as Bluetooth, RFID, IrDA, UWB, ZigBee, NFC, and Wireless USB may be applied to the mobile terminal according to the present invention.

Among them, the NFC module provided in the mobile terminal supports the non-contact type short-range wireless communication between the terminals at a distance of about 10 cm. The NFC module may operate in either a card mode, a reader mode, or a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a UICC (Universal Integrated Circuit Card) (e.g., SIM or USIM), a Secure micro SD and a sticker, a logical medium (e.g., embedded SE (Secure Element)) embedded in a mobile terminal, Lt; / RTI > Data exchange based on SWP (Single Wire Protocol) can be made between NFC module and security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside such as a conventional IC card. Specifically, if the mobile terminal storing the card information of the payment card such as a credit card or a bus card is brought close to the fare payment machine, the mobile local payment can be processed, and the mobile terminal storing the card information of the access card can be accessed If you are close to the time, the approval process for access may begin. Cards such as credit cards, transportation cards, and access cards are mounted on the security module in the form of an applet, and the security module can store card information on the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage details, and the card information of the access card may include at least one of a name, a number (e.g., It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. At this time, the data received from the mobile terminal by the tag may be coded into a data exchange format (NFC Data Exchange Format) defined by the NFC Forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. If the data received from the tag is a smart poster type, the control unit executes a browser (e.g., an Internet browser), and if the data received from the tag is a text type, the control unit can execute the text viewer. If the data received from the tag is a URI type, the control unit executes the browser or makes a telephone call, and if the data received from the tag is of the general control type, appropriate operation can be executed according to the control contents.

When the NFC module operates in a peer-to-peer (P2P) mode, the mobile terminal can perform P2P communication with another mobile terminal. At this time, LLCP (Logical Link Control Protocol) may be applied to P2P communication. A connection may be created between the mobile terminal and another mobile terminal for P2P communication. At this time, the generated connection can be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are exchanged consecutively. Through P2P communications, data such as business cards in electronic form, contact information, digital photos, URLs, and Bluetooth, and set-up parameters for Wi-Fi connectivity can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used to exchange small-sized data.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Hereinafter, embodiments of the present invention will be described by taking the mobile terminal 100 shown in FIG. 1A as an example of a mobile terminal. However, it goes without saying that the mobile terminal according to an embodiment of the present invention may be implemented by the mobile terminals 200, 300, and 400 shown in FIGS.

5 is a block diagram illustrating a digital TV related to the present invention.

The digital TV 500 includes a network interface 501, a TCP / IP manager 502, a service delivery manager 503, an SI decoder 504, A demux or demultiplexer 505, an audio decoder 506, a video decoder 507, a display A / V and OSD module 508, a service discovery manager 510, an SI & metadata DB 511, a metadata manager 512, a service manager 513, A UI manager 514, and the like.

The network interface unit 501 receives the IP packet (s) (IP packet (s)) or the IP datagram (s) Quot;) from the server (not shown) or transmits it to the server. For example, the network interface unit 501 may receive a service, application, content, and the like from a service provider through a network.

The TCP / IP manager 502 is connected to the IP packets received by the digital TV 500 and the IP packets transmitted by the digital TV 500, that is, to the packet delivery between the source and the destination I am involved. The service manager 505, the service discovery manager 510, the service control manager 509, the metadata manager 512, the service discovery manager 510, ) Or the like.

The service delivery manager 503 is responsible for controlling the received service data. For example, the service delivery manager 503 may use RTP / RTCP when controlling real-time streaming data. When the real-time streaming data is transmitted using the RTP, the service delivery manager 503 parses the received data packet according to the RTP and transmits it to the demultiplexing unit 505 or the control of the service manager 513 In the SI & meta data database 511 according to the < RTI ID = 0.0 > Then, the service delivery manager 503 feeds the network reception information to the server providing the service using the RTCP.

The demultiplexer 505 demultiplexes the received packets into audio, video, SI (System Information / Service Information / Signaling Information) data, and outputs them to the audio / video decoder 506/507 and the SI decoder 504 send.

The SI decoder 504 receives the demultiplexed SI data, that is, PSI (Program Specific Information), PSIP (Program and System Information Protocol), DVB-SI (Digital Video Broadcasting-Service Information), DTMB / CMMB Broadcasting / Coding Mobile Multimedia Broadcasting). In addition, the SI decoder 504 may store the decoded service information in the SI & metadata database 511. The stored service information can be read out and used by the corresponding configuration, for example, at the request of the user.

The audio / video decoders 506/507 decode the demultiplexed audio data and video data. The decoded audio and video data is provided to the user through the display unit 508.

The application manager includes, for example, a UI manager 514 and a service manager 513, and can perform a control function of the digital TV 500. [ In other words, the application manager can manage the overall state of the digital TV 500, provide a user interface (UI), and manage other managers.

The UI manager 514 provides a GUI (Graphic User Interface) / UI for a user using an OSD (On Screen Display) or the like, and receives a key input from a user to perform a device operation according to the input. For example, the UI manager 514 transmits the key input signal to the service manager 513 when receiving a key input regarding the channel selection from the user.

The service manager 513 controls the manager associated with the service such as the service delivery manager 503, the service discovery manager 510, the service control manager 509, and the metadata manager 512. In addition, the service manager 513 generates a channel map, and controls the selection of a channel and the like by using the generated channel map in accordance with a key input received from the UI manager 514. The service manager 513 receives service information from the SI decoder 504 and sets an audio / video PID (Packet Identifier) of the selected channel in the demultiplexer 505. The PID thus set can be used in the demultiplexing process described above. Accordingly, the demultiplexer 505 filters (PID or section filters) audio data, video data, and SI data using the PID.

The service discovery manager 510 provides information necessary for selecting a service provider that provides the service. Upon receiving a signal regarding channel selection from the service manager 513, the service discovery manager 510 searches for the service using the information.

The service control manager 509 is responsible for selection and control of services. For example, the service control manager 509 uses IGMP or RTSP when the user selects a live broadcasting service such as an existing broadcasting system, and selects a service such as VOD (Video on Demand) , RTSP is used to select and control services. The RTSP protocol may provide a trick mode for real-time streaming. Also, the service control manager 509 can initialize and manage a session through the IMS gateway 550 using an IP Multimedia Subsystem (IMS) and a Session Initiation Protocol (SIP). The protocols are one embodiment, and other protocols may be used, depending on the implementation.

The metadata manager 512 manages the metadata associated with the service and stores the metadata in the SI & metadata database 511.

The SI & meta data database 511 stores the service information decoded by the SI decoder 504, the meta data managed by the meta data manager 512, and the information necessary for selecting a service provider provided by the service discovery manager 510 . In addition, the SI & meta data database 511 may store set-up data for the system and the like. The SI & meta data database 511 may be implemented using a non-volatile RAM (NVRAM), a flash memory, or the like.

Meanwhile, the IMS gateway 550 is a gateway that collects functions necessary for accessing the IMS-based IPTV service.

Hereinafter, a method for efficiently processing a plurality of processes requested by a terminal according to various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In particular, the present invention relates to an algorithm for efficient process processing between elements of a terminal such as a processor, a memory, and an operating system (OS) according to the present invention, and a hardware approach for the algorithm .

According to the present invention, it is possible to improve the access speed of the terminal by maximizing the efficiency of the system through process management of the terminal, and indirectly improve the heat generation of the terminal and the battery consumption efficiency.

In the present specification, a hardware approach for utilizing an ASID (Address Space Identifier) in cache partitioning is disclosed. However, this is an embodiment, and the scope of the present invention is not limited thereto.

A terminal according to an embodiment of the present invention includes a cache memory for storing mapping information by checking an ASID area accessed by a core identifier, and a processor for receiving the mapping information through a predetermined channel, And converting the ASID into a new ASID.

Here, the cache memory can confirm the ASID area for each TLB work step.

The mapping information may include mapping data between at least two of a core identifier, a physical address, and an ASID.

The cache memory may update the mapping information only when there is a change in the mapping data between the core identifier and the ASID in the mapping information on the mapping data between the core identifier, the physical address, and the ASID.

The cache memory may transmit the mapping information through a predetermined channel only when the mapping information is updated.

Also, the cache memory may compare the physical address and the core identifier stored in the mapping table with the physical address and the core identifier of the request accessed to the target cache memory, and update the ASID mapping information of the corresponding core if they match.

The controller may control conversion of the ASID in the mapping information by comparing the requested physical address and the core identifier with the previously stored physical address and core identifier.

In addition, if the cache memory hierarchy is equal to or greater than a predetermined level, only the mapping information confirmed in the TLB without the request reaching the LLC remains in the mapping table in the control unit, and then the same core identifier, If it is recognized as a wrong core identifier and physical address mapping data due to the physical address mapping data, the mapping information can be erased through the time-out event in the lower cache memory layer.

The controller may re-map using the difference in frequency of the ASIDs approaching the memory area based on the allocation of the memory area for each process (ASID) by the operating system.

Meanwhile, if the ASID allocable number is exceeded and the reallocation proceeds after the ASID flushing in the TLB, the control unit stores the ASID-specific access count for each partition to check the ASID remapping information in the TLB in the cache memory When the ASID is allocated in the TLB and the mapping information is transferred to the cache memory, the count proceeds to change the partition information to the corresponding ASID if the specific ASID count of the partition exceeds a predetermined threshold.

On the other hand, the detailed description of the above-mentioned contents will be described below.

Before explaining the hardware approach, the TLB will be described as follows.

6 is a diagram illustrating a TLB associated with the present invention.

The TLB 620 is an abbreviation of Translation Lookaside Buffer and is a structure for performing an address converting cache function for converting a virtual memory address into a physical memory address. Thus, the virtual memory address requested by the processor (not shown) is converted into the physical memory address in the TLB 620, and the processor becomes accessible to the memory 630. The TLB 620 may be managed and utilized by hardware and an operating system (OS). Here, the operating system (OS) can allocate independent virtual memory space for each process (Process # 1, Process # 2) 612, 614. However, in a multi-threaded process in a process, since a plurality of cores are executed through a single process, a memory space can be shared.

The processor architecture utilizes the ASID in the physical memory (map) 630 shown in FIG. 6 to distinguish the same virtual memory address space allocated to an individual process from a memory management unit (MMU) . In the context of the present invention, the processor is described herein as a mobile processor, as described above, but is not necessarily limited thereto.

In this regard, the ASID can be allocated a predetermined bit (for example, 8 bits) for each process by the above-mentioned OS.

In the present description, the term " process " refers to a process including, for example, a child process derived from a function call in a parent process or a process occurring in a new task It can be meaningful. All threads derived from the same process can share the same ASID.

If a context switching situation occurs, an operating system (OS) can attempt to solve the situation using the ASID. In other words, the operating system (OS) can reduce unnecessary TLB flushing by utilizing the ASID since the system efficiency may deteriorate when context switching occurs.

This can improve the performance of the entire system.

On the other hand, if the cache is managed for each process, it is possible to maintain the consistency of data and management techniques regardless of whether or not the context switching occurs.

On the other hand, since the cache, which is hardware, is transparent to the system, the process ID assigned by the operating system (OS) can not be known. Therefore, it is difficult to manage the process information of the processor unit by linking with the characteristics of the traffic actually occurring in the cache memory.

Therefore, in order to use the cache memory management method of the conventional process unit, it is necessary to modify the operating system (OS) and the compiler.

On the other hand, in order to access it in hardware, ASID information is required in the TLB. And a method of transferring the ASID information from the TLB to the cache memory stage is required.

Hereinafter, an embodiment of a hardware access method for cache management in a process unit will be described herein.

Further, in explaining the hardware approach, it is further required to solve the ASID reallocation problem.

For example, due to the hardware overhead of the TLB, the ASID is limited to 8 bits, as described above, indicating that a lack of space is available to represent the new ASID. Therefore, the ASID index of the TLB may be flushing. When the ASID index is flushed, it is reassigned.

In other words, when the ASID flushing occurs in the above, the ASID can be sequentially reassigned sequentially from the first occurring process. This reassigned ASID can be allocated a different address space than the existing ASID. Therefore, in order to maintain the consistency of management in managing the cache memory with the ASID, the information about the reassignment of the ASID must be identifiable at the cache end.

However, there is a problem in that it is difficult to identify the ASID reassignment information.

In order to solve this problem, the present invention provides a method for enabling identification of ASID information.

For example, in the present invention, ASID information may be transmitted to an LLC (Logical Link Control) unit.

To do this, we first identify the ASID area accessed by the core ID in each TLB walk step. Then, the mapping information is stored in the lower stage of the MMU. Here, the mapping information may be, for example, 'Core ID - Physical Address - ASID', but is not limited thereto.

Also, the MMU sub-stage may include integrated mapping table hardware accessible to all cores.

Meanwhile, the integrated mapping table may be updated when at least one mapping information is changed in the 'Core ID - Physical Address - ASID' mapping information.

For the sake of convenience, however, the present invention is not limited thereto, for example, when the 'Core ID - ASID' mapping information is updated in the 'Core ID - Physical Address - ASID' mapping information.

When the mapping information is updated, it is transferred to an ASID-cache partitioning controller through a separate channel at a cache memory end for managing the corresponding Core ID-physical address-ASID mapping. This is for lowering the transmission cost, for example, because a transmission cost occurs when mapping information is transmitted for every TLB work. Accordingly, when the transmission cost is not taken into account, mapping information may be transmitted for each TLB work differently from the above.

When managing the cache memory, the physical address and the core identifier stored in the controller are compared with each other by referring to the requested physical address and core ID, and converted into the related ASID.

7 is a diagram for explaining a method of updating ASID mapping information according to an embodiment of the present invention.

On the other hand, if the cache memory 730 layer is above a predetermined level, the request does not reach the LLC and only the mapping information identified in the TLB remains in the mapping table 740 in the cache controller.

Here, the predetermined step is, for example, an example of the third stage (L3) of the cache memory 730 layer, which is an embodiment only, but the present invention is not limited thereto.

Therefore, if the same 'core ID - physical address' information is transferred in another process, it may be recognized as a wrong 'core ID - ASID mapping', and malfunction may occur.

For example, in the TLB, the core ID-physical address-ASID mapping information is transferred, but a cache hit may occur before the target cache memory.

If a cache hit occurs before the target start memory, if the cache memory 730 accesses the same physical address later, it can be mapped to a wrong ASID, which may cause an operation to be disabled or a malfunction may occur.

In order to solve the above-described problem, a method of erasing the corresponding mapping information using a time out event in the lower cache memory layer may be used.

The physical addresses 742 and 744 and the core identifiers 712 and 714 stored in the mapping table 720 are compared with the physical addresses 742 and 744 and the core identifiers 712 and 714 of the request accessing the target cache memory. , The ASID mapping information of the corresponding core is updated.

Next, an ASID remapping algorithm according to the present invention will be described.

FIG. 8 is a view for explaining an ASID remapping method according to the present invention, and FIG. 9 is a flowchart illustrating an ASID remapping method according to the present invention.

8 and 9 together, the ASID remapping method according to the present invention will be described in more detail as follows.

First, in the present invention, a method of remapping using a frequency difference of an ASID approaching a memory region based on allocation of a memory region for each process (ASID) by an operating system (OS) will be described as an example.

8A and 8B are diagrams for explaining conversion and counting of the ASID value of the corresponding process, respectively.

In this regard, the ASID assignable number is 255, since it is 8 bits. However, the ASID assignable number is arbitrary and may vary depending on the system.

When a new process (process # 1 [ASID 52]) starts (S902), it is determined whether the number of ASID allocations is 255 (S904).

If more than 255 ASID allocation requests are received, the TLB performs ASID flushing. And the TLB performs the ASID reassignment.

Remapping is performed as ASID is reallocated after ASID flushing in the TLB.

However, in order to check the ASID remapping information in the TLB in the cache memory, hardware to store the ASID-specific access count for each partition must be added.

In the TLB, when ASID 255 (8 bits) is allocated and the mapping information is transferred to the cache memory, the count proceeds (S906). In other words, as a result of the determination in step S904, the allocated ASID has reached 255 and counts for the remapping table.

At this time, if the specific ASID count of the partition exceeds a predetermined threshold (S908), the partition information is changed to the corresponding ASID 810 and re-mapped (S910). And the count is reset.

10 is a diagram illustrating a hardware architecture according to an embodiment of the present invention.

The ASID # 1 1012 and the ASID # 2 1014 communicate with the LLC 1050 and the main memory 1060 via the L2 cache 1020 via a generic bus 1030. [

The ASID # 1 1012 has core 0 and core 1, and the ASID # 2 1014 has core 2 and core 3.

Here, each core includes an L1 cache, a TLB, and an MMU.

In the above, the data of the TLB and the MMU are mapped to the corresponding ASID in the LLC via the ASID basic partition controller 1040.

In this regard, the storage of the ASID mapping information of the core identifier and the physical address unit through the TLB may have the ASID mapping table as shown in FIG.

Meanwhile, in the above, the TLB transmits the update mapping information to the LLC controller when the mapping update occurs.

To summarize, add hardware to store core identifier - physical address - ASID mapping information at the bottom of the MMU. When the TLID is accessed, the mapping table is checked. When the core identifier and the ASID information are updated, the core identifier-physical address-ASID information is transmitted to the ASID basic partition controller 1040. The controller proceeds with cache partitioning based on the ASID based on the transferred mapping information. At this time, the cache partitioning technique may be any known or later developed technique.

In accordance with at least one of the various embodiments of the present invention described above, it is possible to provide a method for efficiently processing a plurality of processes requested by a terminal, and more particularly, to an efficient process processing between elements of a terminal such as a processor, a memory, And a hardware approach for it. Accordingly, the efficiency of the system through the process management of the terminal is maximized to improve the access speed of the terminal, thereby indirectly improving the heat generation of the terminal and the battery consumption efficiency.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet).
