Sistema de memórias multicache para uma máquina paralela mind Projeto Multiplus

Abstract

Today, cache memories are essential devices in many modern computer architectures. Specially in multiprocessor systems, where the communication media between the processors and the memory modules are more susceptible to transfer overloads, a careful specification of a multicache system is of upmost importance to attain the desiredlevels of performance. This work presents a study of various design alternatives for a multicache system to be used in the development of the NCE/UFRJ's high performance MIMD parallel computer named Project MULTIPLUS. In the first part, a brief presentation of the classical aspects involved in cache design is given, with special emphasison the data coherence problem. The architecture of the MULTIPLUS system is shown afterwards. The remaining of the work is then devoted to the discussion and analysis of the design alternatives under the MULTIPLUS perspective.
