We present the design for the two VLSI components used in a processor-to-memory interconnection network for a shared memory system. These components allow the combining of requests that are destined to the same memory location. The design contains both semi-systolic queues and an associative “wait buffer.” Transition equations and schematics of the critical pieces of the design are included.
