Abstract:

In this paper, we propose a network controller design that supports stream data transmission. This design is implemented in the FT64 stream processor. By using it, multiple FT64 processors can transfer data through a hlgh-perforrnance network and perform parallel stream computing. This design adopts a  two-dimensional torus structure, uses virtual channels to avoid deadlock, and supports multiple-stream transmission at the same time. The test results    show that the design＇s function is right, the internal clock frequency is 500MHz, and the link clock frequency is 400MHz.
