An architecture for a DSP field-programmable gate array

摘要

This paper describes an application specific architecture for field-programmable gate arrays (FPGAs). Emphasis is placed on the logic module architecture and channel segmentation for the FPGAs targeted for application areas related to digital signal processing (DSP). The proposed logic module architecture is well-suited for efficient implementation of frequently used logic functions in the DSP application area. This is mainly because it is possible to implement most of these functions using one logic module, which results in a reduction in both the net lengths and the number of antifuses used. The performance improvements are achieved by customizing the logic module architecture and the programmable interconnect to suit the requirements of DSP applications.
