Description
Summary:Godson-2H is a complex SOC of Godson series, which is a 117mm 2 , 152 million transistors chip fabricated in 65nm CMOS LP/GP process technology. It integrates a 1GHz processor core and abundant high and low speed peripheral IO interfaces. Large scale and extremely strict low power requirements make great challenges in the chip design phase. To meet low power constraints in different application scenarios, most of state-of-art low power methods are carefully adopted. This paper describes the most effective low power design methods used in Godson-2H, which are dynamic voltage and frequency scaling, power gating and aggressive multi-voltage design.
