DESIGN AND OPERATION OF DATA SWITCHING-CIRCUITS FOR A SUPERCONDUCTIVE3-NODE PARALLEL PROCESSOR INTERCONNECTION SYSTEM

We have proposed a superconductive packet switching interconnection ci rcuit for a three-node parallel processor system, At each node, the pr ocessor unit communicates with the others through a ring interface cir cuit (called RIF circuit). In this paper, we report the design of the switching protocols of the RIF circuit and the result of an operation experiment on each protocol, The protocols operate successfully at 20 kHz, Additionally, the functions of checking validity and setting vali dity of the packet operate successfully at over 1 GHz.
