The digital signal processing (DSP) applications are in numerous infotainments, medical diagnostics and advanced communication and radar systems. Always the advancement in VLSI technologies will have an impact on the performance of these systems. With the non-terminating nature of the DSP systems, even a small performance improvement in the implementation of an arithmetic functional unit will have a greater impact on the whole system. VLSI DSP deals with such architectural and algorithmic optimization techniques to design high-performance DSP systems.
