Physical Implementation of the 1GHz Godson-3 Quad-Core Microprocessor

The Godson-3A microprocessor is a quad-core version of the scalable Godson-3 multi-core series.It is physically implemented based on the 65 nm CMOS process.This 174 mm~2 chip consists of 425 million transistors.The maximum frequency is 1GHz with a maximum power consumption of 15 W.The main challenges of Godson-3A physical implementation include very large scale,high frequency requirement,sub-micron technology effects and aggressive time schedule.This paper describes the design methodology of the physical im...
