简单介绍了多DSP硬件模块的应用背景。主要介绍了基于美国德州仪器(TI)公司生产的TMS320 VC5416 DSP芯片实现的8 DSP硬件模块实现方法。该模块的结构主要包括多片DSP、FLASH程序加载、JTAG硬件仿真和FPGA等子模块。详细论述了多DSP与FPGA的连接、FLASH存储器与DSP、FPGA的连接,以及硬件仿真所用的JTAG菊花链。并且通过验证该硬件模块运行正确。
Briefly introduced the application background of multi-DSP hardware module. This paper mainly introduces the implementation of 8 DSP hardware module based on the TMS320 VC5416 DSP chip produced by Texas Instruments. The structure of the module includes multi-chip DSP, FLASH program loading, JTAG hardware simulation and FPGA sub-modules. It discusses in detail the connection of multi-DSP and FPGA, the connection of FLASH memory with DSP and FPGA, and the JTAG daisy chain used in hardware simulation. And by verifying that the hardware module is running correctly.
