Technical field

The invention belongs to smart card/design of integrated circuit and application, relate in particular to the smart card designs and the application of high calculated performance, super large memory capacity, high-speed transfer interface.

Background technology

Smart card is IC-card again, is that a kind of integrated circuit (IC) chip that will have storage, encryption and data-handling capacity is embedded in the card in the plastic substrate.Smart card is divided according to the chip of setting-in, can be divided into memory card and microprocessor card two big classes.Memory card adopts memory chip as the core of the card, has only " hardware " to form, and comprises data-carrier store and security logic control etc.; Microprocessor card adopts microprocessor chip as the core of the card, is made up of jointly hardware and software.Hardware components generally includes the hardware microprocessor that is used to calculate and control, when being used for storage running or the random access memory of operational data (SRAM/DRAM/SDRAM), be used for program code stored ROM (read-only memory) and (realize with ROM usually, latest developments are to adopt the non-volatile storer of rewriting, realize as EEPROM/FLASH), be used for the non-volatile storer (EEPROM/FLASH) of rewriting of storaging user data.Software section comprises watchdog routine or COS (Card Operating System, card operating system) and types of applications program etc.Smart card among the present invention just is meant microprocessor card.

The fundamental characteristics of smart card and function have defined in ISO/IEC 7816 series standards.The typical structure of chip card IC as shown in Figure 1; except microprocessor, also comprise four additional function modules usually: the random access memory of operational data (SRAM/DRAM/SDRAM) during storage running, be used for program code stored storer (ROM/EEPROM/FLASH), be used for the non-volatile storer (EEPROM/FLASH) and the serial communication unit (I/O interface) of rewriting of storaging user data as chip core.Above-mentioned five part of module are coupled together and be integrated in the integrated circuit by logical circuit, circuit and safety of data ensure effectively by semiconductor technology and software.

IC-card has outstanding 3S characteristics, and promptly Standard (International standardization), Smart (dexterous intelligent) and Security (security) have advantages such as memory space is big, good reliability, security height.At present, smart card has been widely used in fields such as telecommunications, finance, government, traffic, medical treatment, public administration, internet.

In moving communicating field, be applied as example with smart card, SIM (Subscriber IdentityModule, subscriber identification module) clamps and be loaded in the mobile phone terminal, finished user identity identification and authentication, Speech Communication support, short message service and other all kinds of value-added services on the GSM network based on STK.After the SIM card technology is succeedd in the GSM network, widely applied at present in all kinds of mobile communications networks, used usim card etc. as having used in the cdma network to have used in PIM card, the 3G network in UIM card, the PHS network.Described novel intelligent card technique can use in above-mentioned industry-by-industry and application.

For a long time, basic design concept and inside structure since chip card IC and software engineering have been continued to use it always and be born.On the one hand, smart card techniques has obtained huge business success; On the other hand, smart card techniques also is subjected to the challenge of more and more other new technologies, if can not implement upgrading as soon as possible on technology platform, smart card also is faced with the danger that is eliminated.The capacity of tradition SIM card and adopts 8 bit CPUs between 16K to 128K byte.Because memory capacity is limited, the processing power of 8-bit microprocessor is also very low, and the business that traditional SIM card can be carried out is extremely limited; And operator has changed the competition of application and service over to from rate war, and the business of release becomes increasingly complex, and a large amount of novel mobile value-added service as mobile TV, mobile e-business, multimedia application, all needs to carry out a large amount of mathematical computations and data throughput; Current society also has higher requirement to information security, corresponding cryptographic algorithm also becomes increasingly complex, also need to carry out a large amount of calculating and processing at a high speed as digital signature, digital certificate, DRM (DigitalRights Management, digital copyright management).Since conventional smart card only integrated ISO/IEC 7816 interface communication protocols, this agreement can only read the smart card content on specific smart card terminal equipment, because not general the causing of interface can't directly link to each other with the computer equipment that uses standard interface, telecommunication apparatus etc.This limitations restrict application and the development of smart card in association area.The application of high added value or killer's level is thirsted for releasing by operator, effectively promote its professional income, this just need have memory space and high performance microprocessor above megabyte as the SIM card of unique bridge between connection operator and the user, obviously, traditional SIM card can't satisfy these requirements, can do nothing to help operator and obtain big breakthrough on new business is promoted.

Along with developing rapidly and popularization and application of mobile communication technology, more and more higher to the functional requirement of smart card; For example, on SIM card, realize the RFID function, realize dual user identification module/user identification module multi integrated functionality (many telecom operators), integrated application processor or other be the function (MP3 of control externally, MPEG4, LCD control) or the like, even these novel smart cards have possessed high speed data transfer, the characteristics of mass data processing, but owing to still adopt traditional physical interface form (ISO7816 standard, 8 Pad), the performance of its function expansion and ability is subjected to great restriction.

In addition, new application requirements smart card can bear the outside 2.7V that supplies with to the 5.5V power supply, and provides multiplex operation voltages such as 1.8V, 3V and 5V simultaneously in card inside; And this management to power supply is not rely on exterior terminal equipment, but realize in smartcard internal.But, want to realize on the logic chip in smart card that power management is very difficult, must seek new solution, realize the power management of smartcard internal.

Operator is in order to strengthen own absolute predominance status on industrial chain, constantly develop the value-added service of oneself, and manage to attempt mobile phone producer and business are controlled by various means, but because mobile phone producer is numerous and the distinctive sales mode of mobile phone makes operator to set up on cell phone platform well and unified its business, so this trial produces little effect.And SIM card is as the unique controlled link fully of operator, if can possess vast capacity and superpower computing power, and business development that can carrier-supporting-carrier, will become operator undoubtedly and promote the own professional and industry of acquisition control, prevent a terminal and a professional important means out of control.

Summary of the invention

Purpose of the present invention is intended to solve above-mentioned traditional intelligence and is stuck in the problem that runs in industry development and the technology evolution, and a kind of novel smart card with the high-performance treatments platform that can support the complex calculation business is provided.This novel smart card can carry out the storage and the management of mass data, the transmission of high data rate, and can integrating multiple data transmission interfaces, use as independent memory device.This smart card can be suitable by conversion socket and multiple digital equipment, and have powerful network download ability, encoding multimedia data processing power and safe computing power.

By above-mentioned purpose as can be seen, novel smart card of the present invention is the breakthrough to the revolution of conventional smart card, and the lifting of a matter is all arranged on function and performance.For this reason, on the circumscribed basis of analysis conventional smart card, the key technology problems that novel intelligent calorie requirement of the present invention solves is proposed below:

At first, the CPU of most smart cards is 8 or 16 bit processors in the market, as Intel8051, Motorola 6502 etc., typical clock work frequency is that (clock ranges is between 1MHz~10MHz) for 3.57MHz, the CPU travelling speed is generally 0.5MIPS (Million Instruction PerSecond, million instructions per second) about, carrying out the application processing of normal words class still can support, for a large amount of network processes, the image calculation of calculating of needs, cryptographic calculations etc. then can't be supported well.As RSA signature algorithm commonly used, can require lowest order digit usually is 1024, and some occasion then requires to reach 2048; Even adopt the less relatively ECC algorithm of calculated amount, it is 160 that its lowest order digit also requires, even 192,256; In the multi-medium data process field, in order to improve precision and speed, also need to adopt the processor of 32 above data bandwidths usually, this shows that the computing power of conventional smart card can not satisfy the application and development demand.So high performance calculating is the matter of utmost importance that novel smart card will solve.

Microprocessor is mainly used in calculating, control and communicates by letter.In order to improve the processing power of smart card, the present invention adopts the embedded microprocessor of 16/32/64 (or more high-order), and the CPU travelling speed can be configured and adjust according to application, can reach tens or hundreds of MIPS usually, has promoted processing power greatly; In addition, in order further to improve the processing power of smart card, according to practical situations, can also adopt various types of coprocessors, as multimedia coprocessor, DSP, password coprocessor, under the control of microprocessor and coordinating, instruct at concrete application and to optimize and calculate and quicken, can adopt bus mode, dma mode or other data communication mode to be connected between microprocessor and the coprocessor.

Because the complexity and the scale of novel smart card sharply increase with respect to conventional smart card, adopt traditional method of designing integrated circuit can't realize.Because SoC has high integrated performance, be the main solution that realizes sophisticated functions, the on-chip bus design is a key technical problem.In the present invention, it is integrated to relate to a large amount of high speed data transfer and numerous functional module, therefore, novel smart card of the present invention adopt on-chip bus to improve between its inner group/parts or and external interface between data throughput.Industry member has the on-chip bus standard of a plurality of maturations, can be used in the novel smart card of the present invention as CoreConnect, CAN bus, AMBA (Advanced Microcontroller Bus Architecture) and Wishbone etc.

Because the existing high-speed interface of novel smart card of the present invention, as DMA passage, USB interface, also low-speed interface arranged, as ISO/IEC 7816 interfaces, interruptable controller, therefore, a kind of possible implementation of novel smart card of the present invention is: adopt improved bus structure, as dual-bus structure, article one, bus is used to handle high speed data transfer, article one, bus is used to handle the low speed data transmission, adopts bridge or data mailbox device to connect the exchanges data of carrying out different rates between two buses.According to dual-bus structure, the IS0/IEC7816 interface is received on the bus, high speed interface is then received on another bus, and low-speed interface controller and high speed interface controller are received respectively on the different buses, selects use with control bus by the SoC controller.The SoC controller both can have been enabled a bus separately and select a kind of interface to carry out data transmission, also can enable two buses simultaneously and on IS0/IEC 7816 interfaces and high speed interface, transmit the control data transmission of data independence simultaneously, both can improve data throughout and transfer efficiency, can also improve the extendability and the adaptability of intelligent card interface, enlarge its range of application.Dual bus both can be the bus of same type, as all being high-speed buses, also can be dissimilar buses, as one be high-speed bus, another is a low speed bus.For adaptive with high speed interface, the bus that works together with high speed interface must be a high-speed bus, to guarantee to realize the high-speed transfer of data.Like this, novel smart card can be according to the different bus operation mode of the incompatible selection of different applied field, thereby improves the compatibility of novel smart card, enlarges its usable range.

Internal storage location is some storeies that are centered around the microprocessor periphery, utilizes these storeies, and microprocessor can be finished a basic computing system.Generally comprise the program storage, the data-carrier store that is used to store the basic application data of smart card that are used to store user software, be used to store the random cache of interim store data, can increase memory controller and memory protect unit etc. in case of necessity.Program storage and data-carrier store generally can use all kinds of non-volatile class storeies to realize.Random cache generally can use SRAM or DRAM to realize.Storer can directly be connected on the microprocessor by address/data bus, also can be connected with microprocessor indirectly by on-chip bus.In some cases, for make can be integrated the storer kind more flexible, also can be on sheet the design stores controller, be used for realizing control interface with various types of storage mediums (as FLASH, RAM, SRAM, SDRAM, ROM, EEPROM etc.).

Because the security requirement of smart card product; for various types of memory in the sheet certain access condition restriction to be arranged; usually design MPU (Memory Protection Unit, memory protect unit) is used for ensureing safety of data and integrality in the card, realizes the protection to data and code.Novel intelligent is stuck on the hardware and storage area is divided into several parts, it is provided with different access control conditions to different storeies or storage area, all must just can carry out as reading and writing, deletion through after the corresponding safety certification, prevent unwarranted loading and visit, in case produce hard interrupt notification microprocessor when producing unauthorized access.Then be divided into different mode of operations on software, different mode of operations has different access rights.If the system works pattern then can conduct interviews to all storage areas or control; If user model, then authority is subjected to the part restriction, can only visit and use its open zone; If attempt the access-controlled zone, then produce unauthorized access interrupt notification microprocessor.

Novel smart card is still supported traditional ISO/IEC 7816 interfaces, adopts five traditional line connected modes.Because the transfer rate of this interface is lower, therefore be connected on the on-chip bus of low speed, realize the transfer function of ISO/IEC 7816 agreements.

In order to improve the interface rate of novel smart card, on the basis of realizing ISO/IEC 7816 interfaces, adopt pin multiplexing and agreement autoscan recognition technology, the high-speed transfer interface of integrated multiple main flow of while is as USB, SD, MMC.Like this, can increase substantially on the one hand the transmission speed of novel smart card, on the other hand since integrated be interface bus main flow, standard, not only can support to use widely, and protocol processes also possesses stronger extended capability.Simultaneously, these agreements can be supported the Streaming Media transmission, and also relative with the use annexation of miscellaneous equipment simple.

In order in smart card, to realize the multiple interfaces host-host protocol, keep novel smart card and traditional maximum compatibility of card-reading terminal equipment realization simultaneously, must guarantee the ordering of 8 contacts of conventional smart card and type of attachment constant (to realize compatibility) on the one hand, must carry out signal multiplexing (to realize several data transmission interface agreement) to the part pin on the other hand.In the total interface of novel smart card, what smart card was traditional has determined ISO/IEC 7816 interface signals to have right of priority with basic requirements, and every other interface signal can not produce with it and conflict with multiplexing.According to the analysis that the smart card pin is arranged, as can be seen, ISO/IEC 7816 interface signals have in fact only used 5 pin contacts wherein, there are 3 pins (C4, C6, C8) not use, therefore, the present invention just utilizes these three pins to realize that other high speed signal is multiplexing, on this basis, according to the difference of the concrete signal that transmits, discern different transmission interfaces again.The method of concrete pin signal multiplexing can be respectively as differential data line D+, the D-of USB interface with pin C4, C8, and on this basis, with pin C4 as the DATO line of SD interface and the DAT line of MMC interface, with the CMD line of pin C8, with the clock cable of pin C6 as three kinds of interfaces as SD interface and MMC interface.On the basis of pin multiplexing, the special-purpose high-speed interface controller of the inner employing of novel smart card is realized the high speed data transfer with external unit.The high-speed interface controller is mainly finished the function of three aspects: at first realize the autoscan and the identification of various high-speed interface agreements, secondly, realize various high-speed communication interface agreements, as USB, SD, MMC, finish communication function; At last, control and coordinate each external data interface connection, close or switch, make that the same time can only have a kind of interface in running order in USB, SD, three kinds of interfaces of MMC, all the other two kinds of interfaces are in closed condition; And according to the internal control order these three kinds of interfaces are carried out state and switch.The high-speed interface controller links to each other with microprocessor or dma controller by the high speed on-chip bus.

The I/O control of high speed interface can have two kinds of implementations, and a kind of is centralized and unified controlling schemes, by the SoC controller centralized and unified control is carried out in the I/O of high speed interface; Another kind of for disperseing independent controlling schemes, whether the I/O control of high speed interface is controlled the same time by the work of controlling each communication module and is had only a kind of output circuit in running order by each high-speed communication module oneself control.

As shown in figure 11, in first kind of scheme, each communication module is responsible for a kind of interface signal is discerned and handled, UART (ISO/IEC 7816) communication module 2 is responsible for handling the ISO/IEC7816 interface signal, usb communication module 7 is responsible for handling the USB interface signal, SD communication module 9 is responsible for treatment S D interface signal, and MMC communication module 10 is responsible for handling the MMC interface signal.If certain communication module is judged as useful signal to the signal of input, then it sends interrupt request to SoC controller 5; SoC controller 5 begins to control the corresponding communication module and communicates according to the type of this interrupt request.

UART (ISO/IEC 7816) communication module 2 links to each other with SoC controller 5 by low speed bus 3.Usb communication module 7, SD communication module 9, MMC communication module 10 link to each other with SoC controller 5 by high-speed bus 8.When smart card powered on, if interface 1 has signal, UART (ISO/IEC 7816) communication module 2 produced ISO/IEC 7816 interrupt request, sends to SoC controller 5; SoC controller 5 communicates by low speed bus 3 and UART (ISO/IEC 7816) communication module 2 according to this interrupt type, starts ISO/IEC 7816 interface signal treatment schemees, realizes the function of conventional smart card.

Input control circuit 15 and output control circuit 11,12,13 are controlled its whether gating by SoC controller 5, the same time has only a circuit in running order, promptly or input control circuit 15 work, a perhaps circuit working in 11,12,13 3 of the output control circuits.

As shown in figure 12, in second kind of scheme, the input/output circuitry the 16,17, the 18th of high speed interface is independently controlled by each high-speed communication module.Select circuit 6 to select the work of a high-speed communication module by the high-speed communication module, guarantee to have only an output circuit to work simultaneously; Controlling its input/output circuitry by this module then is in input state or is in output state.

It is one two input three output circuits that the high-speed communication module is selected circuit 6.Because the input of two lines has only four kinds of output states at most, therefore, select for use wherein three kinds of states as the control signal that enables of three kinds of high-speed communication modules, the signal that remaining a kind of state is all disconnected as three kinds of high-speed communication modules, thereby guarantee that the same time has only a kind of high-speed communication module at most by gating, just realized that also the same time has only a kind of function of high speed interface work at most.

After enabling ISO/IEC 7816 interfaces, if need enable certain high-speed communication interface simultaneously, then can send corresponding APDU and instruct to the SoC controller by ISO/IEC 7816 interfaces, start the operating circuit of the corresponding interface by the SoC controller.

Dma controller is used for transmitting mass data by dma mode.DMA is a kind of working method of being carried out exchanges data fully by hardware, generally is used for transmitting at a high speed data in groups.Dma controller directly is connected with on-chip bus.Peripheral hardware triggers the DMA transmission by transmission/received signal.Dma controller can replace microprocessor to take over control to on-chip bus fully according to order, produces address, data-signal and control signal, and exchanges data is directly being carried out between the storer or between storer and the peripheral hardware without microprocessor.Dma controller can increase the address automatically in transmission course, to individual counting number of the word that transmits, and transmits end with interrupt mode to microprocessor report, afterwards the control to on-chip bus is given back microprocessor.

Interruptable controller is used to manage the external interrupt request, as output interrupt request singal when external signal I/O EO or internal system produce fault, so that microprocessor is controlled and handled.Interruptable controller links to each other with microprocessor by on-chip bus, can connect on the low rate bus usually.Interruptable controller should be supported multistage interrupt request, can pass through programmed settings priority.
