An LSI for VDD-hopping and MPEG4 system based on the chip
نویسندگان
چکیده
An LSI is fabricated and measured to demonstrate the feasibility of the VDD-hopping scheme in a system level. In the scheme, supply voltage, VDD, is dynamically controlled through software depending on workload. The VDD-hopping scheme is shown to reduce the power to less than 1/4 compared with the conventional fixed-VDD scheme. The power saving is achieved without degrading the real-time feature of an MPEG4 system.

An Optimization Technique for Low-Energy Embedded Memory Systems
On-chip memories generally use higher supply (VDD) and higher threshold (Vth) voltages than those of logic parts to improve the static noise margin and to suppress the static energy consumption. However, the higher VDD increases the dynamic energy consumption. This paper proposes a hybrid memory architecture which consists of the following two regions; (1) a dynamic energy conscious region whic...

The module-wise dynamic voltage and frequency scaling (MDVFS) scheme is applied to a single-chip H.264/MPEG-4 audio/visual codec LSI. The power consumption of the target module with controlled supply voltage and frequency is reduced by 40% in comparison with the operation without voltage or frequency scaling. The consumed power of the chip is 63 mW in decoding QVGA H.264 video at 15 fps and MPE...
