Efforts to build high-speed hardware for many different entropy coders are limited by fundamental feedback loops. Here is a method that allows for parallel compression in hardware. This parallelism results in extremely high rates, lo0 million symbolskecond or higher. The system is generalizable to any lossless or lossy system with deterministic decompression. Prototype hardware that divides the...

Very high-speed computers may be clnssified as follows: 1) Single Jktmction Strdingle Data Stream (SISD) 2) S i l e Imbnctioa Stream-Multiple Data Stream (SIMD) 3) Multiple hstmcth StrePntSingle Data Stream (MSD) 4) Mnltiple Instroctioo Stream-Multiple Data Stream (”D). “Stream,” as nsed here, refers to the sequence of data or irstructiom as seen by the machine daring tbe execution of a program...

High energy photons are a powerful probe for astrophysics and for fundamental physics under extreme conditions. During the recent years, our knowledge of the most violent phenomena in the Universe has impressively progressed thanks to the advent of new detectors for high energy gamma rays. Observation of γ-rays gives an exciting view of the high energy universe thanks to the current (AGILE) and...

Preliminary process design in 1997 for a new grass roots polymer unit in the Gulf Coast raised the possibility of using a single centrifugal pump instead of two reciprocating compressors to feed ethylene into the reactors. The objectives of this change were lower capital cost, energy consumption, and maintenance expense. Discussion of the possible application led finally to the design, manufact...
