An overview of the MIPS-X-MP project

MIPS-X-MP is a research project whose end goal is to build a small (workstation-sized) multiprocessor with a total throughput of 100-200 mips. The architectural approach uses a small number (tens) of high performance RISC-based microprocessors (10-20 mips each) The multiprocessor architecture uses software-controlled cache coherency to allow cooperation among processors without sacrificing performance of the processors. Software technology for automatically decomposing problems to allow the entire machine to be concentrated on a single problem is a key component of the research. This report surveys the four key components of the project: high performance VLSI processor architecture and design, multiprocessor architectural studies, multiprocessor programming systems, and optimizing compiler technology.
