Verilog Design, Synthesis, and Netlisting of IoT-Based Arithmetic Logic and Compression Unit for 32 nm HVT Cells

Abstract

Micro-processor designs have become a revolutionary technology almost in every industry. They brought the reality of automation and also electronic gadgets. While trying to improvise these hardware modules to handle heavy computational loads, they have substantially reached a limit in size, power efficiency, and similar avenues. Due to these constraints, many manufacturers and corporate entities are trying many ways to optimize these mini beasts. One such approach is to design microprocessors based on the specified operating system. This approach came to the limelight when many companies launched their microprocessors. In this paper, we will look into one method of using an arithmetic logic unit (ALU) module for internet of things (IoT)-enabled devices. A specific set of operations is added to the classical ALU to help fast computational processes in IoT-specific programs. We integrated a compression module and a fast multiplier based on the Vedic algorithm in the 16-bit ALU module. The designed ALU module is also synthesized under a 32-nm HVT cell library from the Synopsys database to generate an overview of the areal efficiency, logic levels, and layout of the designed module; it also gives us a netlist from this database. The synthesis provides a complete overview of how the module will be manufactured if sent to a foundry.
