DSP与PCI总线接口设计及实现

The Design and Realization of Interface between DSP and PCIbus

以AD公司的SHARC处理器芯片为例,介绍一种采用FPGA进行ADSP-2106x与PIC总线的接口电路设计方法,并详细介绍了一种利用FIFO去耦合的设计思想,有效地消除了DSP外部总线与PCI总线数据传输中的瓶颈问题。

In this paper,the author took ADSP SHARC processor as example,described the design method of in-terface between ADSP2106x and PCI bus based on FPGA.One important design idea of using FIFO to decouple data transfers between buses is also presented,which effec-tively eliminate the data transfer bottle neck.
