Abstract
The wormhole routing is a key technique in the design of Dawning 1000 which is the first MPP system made in China. In this paper, the wormhole routing is introduced, and an algorithm based on wormhole routing, a chip architecture and its logic design are also described. Finally, an interconnection constructed by the wormhole routing chips is put forward for Dawning 1000 which indicates this kind of chip has a correct function and fast rate with reliability.
