Research on the Design of Step-up Inexact MAC (IMAC) Unit for DSP Applications

September 4, 2020 Engineering 0

Digital Signal Processing is the processing of the analog signal into digital signal. Present epoch of
Digital Signal Processor’s need a rapid and very compacted processor’s. The Digital Signal
Processing enables the analog audio and video signals to process, transmit, store, reproduce and
manipulate the information from one form to another form. But size of the system increases if the all
the processing is to be done and as the size increases the delay also increases. Area of the system is
very important parameter to be considered than the accuracy in the present constraint. Hence we
concentrate on reducing the area and increasing the speed of the processor. Hence in this paper we
state the concept of inexactness and we apply the same to some DSP processor application. This
paper was designed using MIPS Verilog HDL. The design was synthesized and simulated in Xilinx
14.2 ISE. The power Calculations were calculated using Isim, a tool of Xilinx Xpower Analyzer.
