Flexible Parallel Picture Processor Having Various Processing Modes

Parallel Processing System Design with "Propeller" Processor

This is a technical and experimental report of parallel processing, using the "Propeller" chip. Its eight 32 bits processors (cogs) can operate simultaneously, either independently or cooperatively, sharing common resources through a central hub. I introduce this unique processor and discuss about the possibility to develop interactive systems and smart interfaces in media arts, because we need...

Optical content-addressable parallel processor for high-speed database processing.

We extend the concept of optical content-addressable parallel processing [Appl. Opt. 31, 3241 (1992)] to a novel architecture designed specifically for the parallel and high-speed implementation of database operations called optical content-addressable parallel processor for relational database processing (OCAPPRP). An OCAPPRP combines a parallel model of computation, associative processing, wi...

A Parallel Processor Chip for Image Processing and Neural Networks

At AT&T Bell Laboratories we have developed two neural-network chips: (i) the NET32K chip [1] with 32,768 1-bit processing elements which is well suited for image-analysis tasks such as feature extraction and (ii) the ANNA chip [2] with 4,096 3/6-bit processing elements designed for high-speed character recognition using our neural-net based optical character recognition (OCR) algorithms [3, 4]...

Application Scheduling and Processor Allocation in Multiprogrammed Parallel Processing Systems

When large-scale multiprocessors for parallel processing are subjected to heavy diverse workloads of applications, it will be necessary to schedule them in a multiprogrammed fashion in order to use the system resources effectively and keep response times low. Information about the characteristics of individual applications can be used to achieve effective scheduling. We identify some useful par...
