Physical Design Methodology for Godson-2G Microprocessor

The Godson-2G microprocessor is a high performance SOC which integrates a four-issue 64-bit high performance CPU core(called GS464),a DDR2/3 controller,a HyperTransport controller,a PCI/PCI-X controller,etc.It is physically implemented in 65 nm CMOS process and reaches the frequency of 1GHz with power consumption less than 4 W.The main challenges of Godson-2G physical implementation include nanometer process technology effects,high performance design targets,and tight schedule.This paper describes the key i...
