LSI Arithmetic Devices For Real Time Digital Signal Processing
Shlomo Waser · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1979
Real time digital signal processing requires large amounts of number crunching to be performed at high speed. The purpose of this report is to provide the state-of-the-art of high speed arithmetic integrated circuits (ICs). In order to understand the difficulties encountered in fabricating high speed arithmetic ICs, we start the article with a discussion on semiconductor technology. Next, we survey the various arithmetic elements that are available in monolithic form: ALUs, Data Slices, Multipliers, Floating Point Processors, and ROMs. Finally, we conclude with a comment on digital signal processing as a driving force for arithmetic ICs. NOTE: The report assumes knowledge of the basic arithmetic algorithms. Those desiring more background information can refer to [WAS 79a].
