Digital Signal Processing Hardware

This research develops a domain-specific hardware synthesis framework for digital signal processing (DSP) computations. By incorporating domain-specific knowledge of mathematics and algebra into a synthesis tool, the proposed framework can manipulate a math-level transform description to optimize a DSP transform implementation at the algorithmic and architectural design level. This research is affiliated with the SPIRAL project. This research is supported by the DARPA PERFECT program. This research has been supported in the past in part by an NSF ITR Award, the DARPA DESA program and C2S2 FCRP.
