Analysis of IP Based Implementation of Adders and Multipliers in Submicron and Deep Submicron Technologies

Datapath is at the heart of the microprocessor whose performance is a key factor which determines the performance of the processor. Adders and multipliers are the key elements in the datapath which usually are a measure of the performance of the datapath. So, with scaling of MOS transistors down into the deep submicron regime, it is necessary to investigate the performance of these key elements at such small device sizes. This thesis focuses on investigating the performance of existing architectures of adders and multipliers in the submicron and deep submicron technologies at the physical implementation level. Also, an effort has been made to investigate the performance of pipelined implementations of these architectures. Verilog HDL instantiations of adders and multipliers that are available with the DesignWare Building Block IP of Synopsys have been utilized in this thesis. The entire process of the design right from synthesis of the design down to power analysis of the design has been carried out using various EDA tools and has been automated using scripts written in TCL.School of Electrical & Computer Engineerin
