SYNAPSE-1: a high-speed general purpose parallel neurocomputer system

This paper describes the general purpose neurocomputer SYNAPSE–1 which has been developed in cooperation between Siemens Munich and the University of Mannheim. This system contains one of the most powerful processors available for neural algorithms, the neuro signal processor MA16. The prototype system executes a test algorithm 8,000 times as fast as a Sparc–2 workstation. This processing speed...

A High - Speed General - Purpose Externally Compensated

Although most modern monolithic solid state operational amplifiers (op-amps) are internally compensated, externally compensated units provide an invaluable degree of freedom to analog designers. As a result, these op-amps offer true 'general purposeness,' since allowing the user to choose the amplifier's compensation can drastically improve performance in many applications. This thesis proposes...

A High-Speed User-Level Communication Mechanism for the General-Purpose Massively-Parallel OS: SSS{CORE

1 はじめに 並列計算機システムへの汎用性(マルチユーザ・ マルチジョブ)導入による保護機能の実現や実資源 の仮想化は並列処理性能の大幅な低下の原因となる ため、現状の並列計算環境および並列計算機は基本 的にバックエンドプロセッサとしてバッチ処理で使 用されることが多い。つまり、ソフトウェアによる 様々な最適化方式の適用および軽い通信同期手法が システムの独占的使用を要求し、システムの柔軟か つ汎用的な使用形態と相容れないのである。 このような状況を改善するため、我々は 1989年 よりすべての CPUから等距離でアクセス可能な 集中共有メモリを持つ Uniform Memory Access (UMA)型並列計算機を対象にして、ユーザによ る最適化を支援する汎用オペレーティングシステム 核 SS{CORE [1]を研究開発してきた。 SS{CORE の研究においては議論を単純化する...

Implementation of a general-purpose stored-program digital optical computer.

The implementation of what we believe to be the first stored-program digital optical computer is described. The implementation domain consists of lithium niobate directional couplers that are modified to provide optical control and are interconnected with single-mode fiber. The architecture is also the first to employ time-of-flight synchronization. That is, there are no flip-flops used as sync...
