This paper describes a new LSI chip set developed to provide a simple and cost-effective means for DSP hardware implementation. This chip set, consisting of two NMOS LSIs, contains enough logic and memOry to perform such high level DSP functions as biquad lilters and FFT buttef lies at a high throughput rate, without any other external logic devices. It employs serial arithmetic and operates at a clock rate up to mote than 5 MHz, Throughput rate can be traded-off with processing accuracy. Architecture is designed to pursue self-sufficient applicability to high level DSP functions, while retaining generalit' in application.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
