”T800, THOR and SPARC, a performance analysis”

 

This document discusses six computer designs using the T800 Transputer, the SAAB Thor and the Cypress SPARC microprocessors respectively. The purpose is to evaluate hardware aspects of the three processors in two different configurations, a minimum configuration and a maximum configuration. The "paper designs" are indented to give an estimation of:

·          maximum possible instruction execution rate

·           required number of devices

·           area of printed circuit board

·           power consumtion

·           failure rate

The following tables summarises the results:
