The application of an Actel field programmable gate array in the design of an ECG RR interval recorder

Abstract

Field Progammable Gate Arrays (FPGAs) allow dgtal circuitry to be integrated on to a single device without the long time penalty incurred with mask programmable Application Specific Integrated Circuits (ASICs). This makes FPAGA technology an attractive option to engineers involved in designing digital circuitry where space is at a premium. Furthermore, the relatively low cost qf FPGAs at low volume, compared to mask programmable ASICs make them an excellent prototyping option for designers who are considering low cost volume production with mask programmable ASICs. There are several different types of FPGA available which thus creates confusion for prospective users uncertain of their relative benefits. This paper serves as an introduction to FPGA technology and the stages involved in implementing a design, via the application of and Acterl FPGa to the development of an ambyulatory long term electrocardiogram (ECG) based RR interval recorder.
