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.
