Intra-cluster storage concurrent access local-preference switching circuit in array processors

Abstract

The invention discloses an intra-cluster storage concurrent access local-preference switching circuit in array processors, is mainly applicable to data concurrent access functions of intra-cluster distributed storage structures in the array processors, belongs to the technical field of integrated circuit design, and aims at reducing storage access delay, improving access bandwidth and improving a resource utilization rate through a multilevel switching structure and a local-preference access strategy. According to the design, a three-level switching structure of local switching+global switching+local switching is employed; the concurrent access of 4*4 array processors to 16 distributed storage blocks is realized, the concurrency of local data access is improved, the global access delay is reduced, and the storage structures are simplified.

Description

technical field

[0001] The invention belongs to the technical field of integrated circuit design, and in particular relates to data parallel access of a distributed storage structure in a 4*4 processor array cluster in an array processor. Background technique

[0002] With the development of integrated circuit technology, the traditional processor performance improvement method is still used: continuously increasing the main frequency and developing instruction set parallelism, there are problems of rapid increase in design complexity and excessive power consumption, and the continuous increase of main frequency makes The problem of "storage wall" is becoming more and more prominent. In order to adapt to the development of integrated circuit technology and maintain Moore's Law, integrating dozens or even hundreds of simple processor cores on a single chip has become a trend in the development of computer architecture. However, with the advancement of technology, more and mor...
