Abstract

The IBM POWER4 is a new microprocessor organized in a system structure that includes new technology to form systems. The name POWER4 as used in this context refers not only to a chip, but also to the structure used to interconnect chips to form systems. In this paper we describe the processor microarchitecture as well as the interconnection architecture employed to form systems up to a 32-way symmetric multiprocessor.
