Hathi-2 is a reconfigurable general-purpose looselycoupled MlMD multiprocessor system consisting of 100 32-bit lMS T800 transputers and 25 76-bit lMS T212 transputers. Hathi-2 has a distributed switching network and a distributed control system which contains an

Low-Power L2 Cache Architecture for Multiprocessor System on Chip Design
free download

Abstract:Significant portion of cache energy in a highly associative cache is consumed during tag comparison. In this paper tag comparison is carried out by predicting both cache hit and cache miss using multistep tag comparison method. A partially tagged bloom filter

Self-Tuned Distributed Multiprocessor System
free download

Abstract. Self-tuning, a technique devised by Ted Kehl, is a new clocking paradigm which incorporates the best features of conventional synchronous logic along with advantages offered by the asynchronous, self-timed paradigm. The principles of self-tuning are

A Modular Expandable Multiprocessor System with Fault Tolerance
