Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the method and device in the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] Method example:

[0049] The specific operation process of a single call of a single module is as follows: figure 1 As shown, it specifically includes the following steps:

[0050] 102. The main controller configures a DMA interface module and a hardware accelerator module, and sets the hardware accelerator module to adopt a DMA startup mode;

[0051] In this step, the main controller is configured with a DMA interface module and a hardware accelerator module. After the hardware accelerator module is started in a DMA startup mode, the DMA interface module performs data transfer. After completion, the hardware accelerator module is started and the hardware accelerator module runs.

[0052] 104. The hardware accelera...

Abstract

The present invention relates to the field of on-chip systems, in particular to a method and device for invoking system-on-chip modules. The method includes: a master controller configures a DMA interface module and a hardware accelerator module, and sets the hardware accelerator module to start in a DMA startup mode; the hardware accelerator module After running, send an interrupt to the interrupt processing module; the interrupt processing module receives the running completion interrupt sent by the hardware processing module, sends a response to the main controller, and the main controller configures the DMA interface module to output data; the interrupt processing module receives the output of the DMA interface module When the data is completed and interrupted, the call ends; the device includes a main controller module, an interrupt processing module, a DMA interface module, and at least one hardware accelerator module; the present invention can reduce the number of DMA interruptions received by the main controller, simplify the operation process, The time for the main controller to process data is reduced.

Description

technical field [0001] The present invention relates to the field of on-chip systems, in particular to a method and device for calling system-on-chip modules Background technique [0002] At present, the high-speed system-on-chip (SoC, system on chip) has two relatively large development directions, one is software-defined radio frequency (SDR, Software Defined Radio), which, through its reprogramming and reconfigurable capabilities, enables The device can be used in multiple standards, multiple frequency bands, and realize multiple functions. SDR increases the flexibility of the software; another direction is to add a dedicated hardware accelerator, combined with a microprocessor (MCU, Microprogrammed Control Unit) or digital signal The processor (DSP, Digital Signal Processor) does simple calculation and control, and can better consider low power consumption design. [0003] In SoCs based on hardware accelerators, generally speaking, direct memory access (DMA, Direct Memo...
