Low-power shared memory architecture power mode for mobile system-on-chip

Abstract

This paper presents dynamic power saving schemes for low power operation in the modem system shared memory architecture of mobile system-on-a-chip (SOC). Different power modes are considered to obtain the minimum power consumption in a modem operation. An electronic system level (ESL) virtual platform is implemented to verify the proposed scheme with real traffic data extracted from the actual phone. Experimental results show that the proposed method reduces the power consumption by 42% and 15% in 2G and 3G respectively.
