We extend our analysis of the data-dependent quantized voltage level selection (DDLS) technique for dynamic supply voltage scaling (DSVS) systems. The energy analysis was performed using a very conservative energy model considering all combinations of two, three and four quantized voltage levels, and the minimum-energy-yielding quantized voltage levels were selected. For test data, we used nine 300-frame MPEG-2 video sequences in QCIF (Quarter Common Intermediate Format). Our results indicate that energy savings of up to 12% are achievable by selecting quantized voltage levels based on the workload distribution.
