Detailed Description
As described above, some of the prior art schemes configure a dedicated DDR for the modem, which can meet the data buffering requirement of the modem, but the implementation cost is high. Some schemes configure the shared DDR for the modem to meet data caching requirements while reducing product cost. However, the external memory access usually involves a problem of excessive access delay, and cannot be applied to some application scenarios requiring high real-time performance.
In the embodiment of the invention, the first storage module shared by the modem and the processing device can reduce the storage capacity of the second storage module so as to reduce the cost of the modem; the second storage module is arranged for the modem, so that the real-time performance of the modem can be improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a communication apparatus in an embodiment of the present invention is shown. In an embodiment of the present invention, the communication apparatus may include a processing device 11, a first storage module 12, a second storage module 13, and a modem 14.
In a specific implementation, the processing device 11 may be an Application Processor (AP), or may be another electronic component independent of the modem 14 and capable of implementing data processing.
In an implementation, the first storage module 12 may be coupled to the modem 14 and the processing device 11, respectively. The first memory module 12 may store therein data required for the operation of the processing device 11 and data required for the operation of the modem 14, that is, the processing device 11 and the modem 14 may share the first memory module 12. When the communication device is in operation, the processing device 11 and the modem 14 can perform data reading, writing, erasing and the like on the first storage module 12.
In a specific implementation, the first storage module 12 may be divided into at least two storage areas in advance, wherein one storage area may be used for storing data required by the processing device 11 during operation, and the other storage area may be used for storing data required by the modem 14 during operation. When the first storage module 12 is divided into at least two storage areas, the address space division may be implemented in an address interval division manner, and there is no intersection in the address spaces corresponding to different storage areas.
For example, the first memory module 12 is divided into a region a, a region B, and a region C, and the address intervals of the region a, the region B, and the region C are independent of each other and do not intersect with each other.
In other words, in the embodiment of the present invention, the first storage module 12 may be divided into a plurality of independent storage areas to avoid data cross-connection between different processing devices 11 and between the processing devices 11 and the modem 14.
It will be appreciated that one or more regions of the first memory module 12 may also be shared by different processing devices 11, or shared by the processing devices 11 and the modem 14.
In a specific implementation, the second memory module 13 may be coupled only to the modem 14. In the embodiment of the present invention, the second storage module 13 may be a dedicated storage module of the modem 14, wherein the stored data is data required during the operation of the modem 14.
Referring to fig. 2, a schematic structural diagram of a modem 14 in an embodiment of the present invention is shown.
In an implementation, with reference to fig. 1 and 2, the modem 14 may include a storage control module 141, and the storage control module 141 may be coupled to the second storage module 13. When receiving the data processing request, the memory control module 141 may determine whether to access the first memory module 12 or the second memory module 13 according to the address corresponding to the data processing request.
In practical applications, the modem 14, the processing device 11, etc. belong to a physical layer, and an application layer can be regarded as an upper layer of the physical layer. When the upper layer needs to perform data processing operation, a data processing request is generated and issued to the physical layer, the physical layer executes corresponding data processing operation and feeds back the obtained processing result to the upper layer. The data processing request issued by the upper layer may generally include a type and an address corresponding to the data processing. For example, the data processing request is to read data a, and the corresponding address is the address where data a is stored.
The memory control module 141 of the modem 14, after receiving the data processing request, may obtain an address corresponding to the data processing request, and further determine whether an address space corresponding to the address is in the first memory module 12 or the second memory module 13. If the address space corresponding to the address is in the first storage module 12, the storage control module 141 accesses the first storage module 12; if the address space corresponding to the address is in the second storage module 13, the storage control module 141 accesses the second storage module 13.
In a specific implementation, since the processing device 11 and the modem 14 share the first storage module 12, the first storage module 12 with a larger capacity can be provided. The second memory module 13 is a memory module dedicated to the modem 14, so that a smaller capacity of the second memory module 13 can be provided. In the embodiment of the present invention, the storage capacity of the first storage module 12 may be set to be larger than that of the second storage module 13.
For example, the storage capacity of the first storage module 12 may be set to 512M, and the storage capacity of the second storage module 13 may be set to 128M.
In a specific implementation, the storage control module 141 may communicate with the first storage module 12 through a data BUS (BUS) to perform corresponding operations on the first storage module 12 according to the data processing request.
In practical applications, there are some application scenarios that require high real-time performance, such as a voice call scenario. In the embodiment of the present invention, the data for executing the application scenario with high real-time requirement may be stored in the second storage module 13, and the data for executing the application scenario with low real-time requirement may be stored in the first storage module 12.
In a specific implementation, the first memory module 12 may be a memory module corresponding to the processing device 11. In general, the storage capacity of the first storage module 12 is large, and the first storage module 12 may have a certain storage space that is not used by the processing device 11. Therefore, in the embodiment of the present invention, the unused storage space in the first storage module 12 can be fully utilized and used for storing the data with low real-time requirement corresponding to the modem 14.
Therefore, the modem and the processing device share the first storage module, the storage capacity of the second storage module can be reduced, and the cost of the modem can be reduced. The second storage module is specially arranged for the modem, and the second storage module stores data with higher real-time requirement, so that the real-time performance of the modem can be improved.
In a specific implementation, a buffer module 143 may be further disposed in the modem 14, and the buffer module 143 may be coupled to the storage control module 141 and adapted to buffer the history data recently accessed by the storage control module 141. The cache module 143 may be a primary cache, a secondary cache, or the like.
The storage control module 141 may read the cache module 143 when receiving the data processing request. If the hit can be found from the cache module 143, the read result is directly returned; if the data processing request fails to hit the cache module 143, the storage control module 141 determines the corresponding storage module according to the address corresponding to the data processing request.
Since the cache module 143 stores the history data accessed by the storage control module 141, if the history data includes data corresponding to the current data processing request, the data can be directly read from the cache module 143 and returned. Since there is no need to search for data from the memory module, the data is read from the memory module 143 faster than it is read from the memory module.
In practical applications, the storage capacity of the cache module 143 is usually small to save cost, so that the data that can be stored therein is limited. Therefore, the history data cached by the caching module 143 may be data with the highest access frequency in history by the storage control module 141.
The data cached by the cache module 143 may also be updated, and when the data stored therein reaches the upper limit of the cache module 143, some data may be deleted therefrom and new data may be added.
In a specific implementation, the modem 14 may further include an interface unit 144, and the modem 14 may communicate with the processing device 11 via the interface unit 144 based on a serial bus. In the embodiment of the present invention, the modem 14 may communicate with the processing device 11 through a Peripheral Component Interconnect Express (PCI Express) standard.
In a specific implementation, the modem 14 may further include a function module 142, and the function module 142 may be a Microprocessor (MCU) of the modem 14, a hardware accelerator of the modem 14, or the like.
In the embodiment of the present invention, the first memory module 12 may be a DDR, and the second memory module 13 may also be a DDR.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
