基于FPGA和多DSP的并行信号处理系统的实现

Implementation of Parallel Signal Processing System Based on FPGA and Multi-DSP

为了克服在高速实时信号处理领域中传统单DSP系统处理能力的瓶颈,多DSP并行处理技术应运而生,成为当前该领域研究的热点。该文提出了一种基于FPGA内部的软FIFO互连结构和4片TI公司的高性能浮点型DSP——TMS320C6701构成的多个DSP之间通信的并行信号处理系统。

In the field of high-speed real-time signal processing, the conventional single-chip system can hardly achieve goals due to poor processing ability. Therefore, multiple-processor parallel signal processing system turns to be the focus. The paper presents a parallel processing system based on 4 chips of TMS320C6701——high performance floating-point DSP of TI. The system accomplishes the communication between DSPs through the software-FIFO architecture in FPGA.
