Analysis and Design of High Performance, Low Power Multiple Ports Register Files

This paper talks about how to analyze and design high performance low power multiple-ports register file circuitry, which is mostly used on mu-P and DSP chip. Firstly, in this paper, we discuss basic concept of register files. Secondly we introduce the different types of register file architecture. Then we analyze and compare design trade-offs among those approaches. With that, we decide the suitable register file circuitry for our application. Then, we start to analyze the low power design style for each block. Finally, we achieve design goal of low power and high performance register file circuit compare to some other designs. It is fabricated by TSMC 0.13mum 1p8m 1.2v process. Simulation result shows the design has the fine 0.013 mW/MHz-port
