摘　　要：本文介绍了BWDSP100芯片的高速互联接口——链路口的实现方法,功能验证结果表明,模块功能覆盖率和代码覆盖率均达到100%,符合设计要求。同时给出了流片后BWDSP100芯片和FPGA链路口互联测试结果,结果表明300MHz下模块功能正确且传输稳定可靠。In this article we propose a method to design a high-speed Link port for BWDSP100. First the architecture of DSP is introduced, then the implementation of Link port is discussed in detail, including the configure registers and the transport protocols, and a hardware architecture is presented next. Finally, results of function simulation and FPGA verification is given, which indicate that the design can be worked correctly and steadily at 300MHz.
