高速数字电路中的数据交换实现方法研究

Study of the Implementation of Data Communication in the Real-time Digital Circuit

在高速数字电路中,多个处理器之间的数据交换往往成为系统设计的瓶颈之一,文中介绍了Altera公司的FPGA和AD公司TigerSHARC系列DSP-TS101之间通信的几种方法。分别论述了在总线方式和链路口方式下二者通信的基本原理和具体实现电路。实际测试结果表明:设计的电路稳定可靠,性能指标满足系统要求。

In the real-time digital circuit, the data communication of the muhi-processor is always a bottleneck in the system design. Communication between FPGA of Altera company and DSP-TS101 of AD company is implemented both in the bus mode and link mode. The test result indicates that the circuit is stable and the performance meets the need of the system.
