基于EP2C35的DSP阵列板通信接口设计与实现

Design and Realization of Communication interface in DSP Array Board Based on EP2C35

基于EP2C35的FPGA能力,实现DSP的Cluster Bus和PCI9054本地端总线的接口转换,如地址映射、中断DSP阵列板,使DSP阵列板具备PCI总线通信能力,同时把DSP的Link口与100M网口之间的转换,如Link口接口模块、FIFO等,使DSP阵列板具备网络通信接口能力,提高DSP阵列板的通信扩展接口能力,增加其应用能力和范围。同时指出,基于FPGA,根据需要,可以进一步扩展更多和更高性能的接口。

Based on field programmable gate array in EP2C35,the Cluster Bus of DSP and pci9054 local bus interface can be converted to each other,such as the address mapping,interrupt of the DSP array board.It makes DSP array board have PCI bus communication capabilities.And the DSP Link port and 100M Ethernet ports can be converted to each other also,such as Link port interface module,FIFO etc,it makes the DSP array board have the ability of network communication interface.
