Embodiment

[0073] Such as Figure 4 As shown, in the embodiment of the present invention, the DSP single board adopts the TMS320F2823x DSP single board of TI, and the FPGA adopts the cyclone IV 4CE6FPGA of Altera. Of course, other types of DSP boards and FPGAs can also be used.

[0074] The DSP single board is connected to the internal RAM space of the FPGA through its external expansion interface (interface 1). Specifically, the XTINF module of the DSP can be used to realize the interface 1, and the RAM space is configured as a shared memory area for storing high-speed interaction between the DSP and the FPGA. The data.

[0075] In the embodiment of the present invention, the RAM in the FPGA is used as the external expansion memory of the DSP, and a dedicated memory space is allocated. In addition to the simulation data interaction during the simulation, the interface 1 will also undertake such as communication data and protection information interaction during normal system operation....

Abstract

The invention provides a DSP software verification system and method. The system comprises: an FPGA / CPLD used for simulating a peripheral circuit of a DSP single board via software; a random access memory RAM; the DSP single board connected with the RAM and used for running DSP software and outputting an operation result to verify whether the DSP software is correct; and the DSP single board sends data sent to the peripheral circuit to the RAM in a process of running the DSP software, when the data need to be read from the peripheral circuit, the data are read from the RAM, the FPGA / CPLD reads the data sent by the DSP software from the RAM through the peripheral circuit simulated by the software and sends the data to the RAM, when the data need to be sent to the DSP software. According to the DSP software verification system and method provided by the invention, no additional hardware cost or expensive verification system is required, and the DSP software is verified by simulation closest to the real system.

Description

technical field [0001] The invention relates to the technical field of software detection, in particular to a digital signal processing DSP software verification system and method. Background technique [0002] The DSP (Digital Signal Processing, digital signal processing) single board is connected with peripheral circuits, runs DSP software on the DSP single board, and realizes various functions by interacting with the peripheral circuits. [0003] In order to verify whether there is a problem with the DSP software running on the DSP board, there are two traditional DSP software (HIL, hardware-in-the-loop) verification schemes: [0004] 1) Matlab software + emulator + DSP single board mode [0005] Such as figure 1 As shown, the Matlab software is run on the PC, and there is an interface model corresponding to the DSP in the Matlab software. Since the interface on the PC cannot directly communicate with the DSP board, the interface model is responsible for exchanging data...
