Experimentation with a two-level microprogrammed multiprocessor computer

Abstract

MUNAP (MUlti-NAnoProgram machine) is a two-level microprogrammed multiprocessor computer designed and developed at a university as a research vehicle. This paper describes the experiences with the implementation of MUNAP. We start with a brief overview of the machine. We then describe the system organization both on hardware and support software. The architectural hierarchies defined on the basic hardware and software systems are described in detail. We conclude the paper with a list of the lessons we have learned from the experience.
