In many parallel applications, network latency causes a dramatic loss in processor utilization. This paper examines software controlled access pipelining (SCAP) as a technique for hiding network latency. An analytic model of SCAP brieey describes basic operation techniques and performance improvements. Results are quantiied with benchmarks on the Cray-T3E. The benchmarks used are Jacobi-iterati...

Fig. 1: Mpeg-4 Coding Scheme

A programmable processor architecture for MPEG-4 video is proposed, that can serve as a coprocessor module in MPEG-4 decoder systems. It consists of a 64-bit dual-issue VLIW macroblock engine, a separate RISC core for bitstream parsing and system processing, and an autonomous I/O processor. A separate DSP is used for MPEG audio support. The architecture is fully programmable and supports parall...

The primary goal of Evolutionary Phonology is to explain recurrent sound patterns in spoken languages across time and space. One domain of explanation is diachronic, and much of my own work has focused on diachronic explanations (e.g. Blevins 2004, 2006a, To appear a, To appear b, To appear c, this volume). Another domain of explanation is synchronic. A range of synchronic factors, from the mec...
