An architecture for a DSP field-programmable gate array

摘要

This paper describes an application specific architecture fornfield-programmable gate arrays (FPGAs). Emphasis is placed on the logicnmodule architecture and channel segmentation for the FPGAs targeted fornapplication areas related to digital signal processing (DSP). Thenproposed logic module architecture is well-suited for efficientnimplementation of frequently used logic functions in the DSP applicationnarea. This is mainly because it is possible to implement most of thesenfunctions using one logic module, which results in a reduction in bothnthe net lengths and the number of antifuses used. The performancenimprovements are achieved by customizing the logic module architecturenand the programmable interconnect to suit the requirements of DSPnapplications
