VLSI Synthesis of Multiply and Accumulate Structures Using Distributed Arithmetic

New consumer devices heavily rely on accessible digital signal processors. Every DSP Core now includes a Multiply and Accumulate unit (MAC), which serves as a key building element and that offers a guide to evaluate for use in product or application. Various MAC cores that depend on signal control in the data path are presented in this study. Despite using Harvard architecture, the majority of DSP processors can extract samples and coefficients quickly enough for real-time applications. By utilizing shifters and adders, distributed arithmetic(DA) is a technique that may be used to accomplish the inner dot product between two signals: fixed and variable signals. This paper shows how the parameter of inputs in the datapath affects different MAC cores. By using DA approach for 1BAAT single LUT, 2BAAT single LUT, 1BAAT two LUT, and 2BAAT two LUT, the proposed design will be executed for a 16-bit MAC structure. The outcomes of the suggested MAC structures will then be composed with a traditional DA structure of equal length. By comparing the 2BAAT two LUTs are better compared to a single 1BAAT LUT, the performance evaluation enables a reduction in dynamic power of 39.93%. Xlinix Vivado 2019.1 can be used to assess the Simulations and Synthesis of these designs.
