AN ARCHITECTURE FOR A DSP FIELD-PROGRAMMABLE GATE ARRAY

This paper describes an application specific architecture for field-pr ogrammable gate arrays (FPGA's). Emphasis is placed on the logic modul e architecture and channel segmentation for the FPGA's targeted for ap plication areas related to digital signal processing (DSP). The propos ed logic module architecture is well-suited for efficient implementati on of frequently used logic functions in the DSP application area. Thi s is mainly because it is possible to implement most of these function s using one logic module, which results in a reduction in both the net lengths and the number of antifuses used. The performance improvement s are achieved by customizing the logic module architecture and the pr ogrammable interconnect to suit the requirements of DSP applications.
