Abstract :
Godson-3A is a quad-core version of Godson-3 series which is a 174 mm2, 425 million transistors chip fabricated using 65 nm CMOS LP/GP process technology. It can be running at 1 GHz with less than 15 W power consumption. Large scale, high frequency, low power and tight time schedule make great challenges in the chip design. To overcome these challenges, a design methodology based on ASIC combining with semi-custom (manual placement and routing using standard cells) and full-custom is adopted. This paper describes the implementation of Godson-3A microprocessor and the methodology used in the chip design.
