Low-power video decoding with dynamic voltage scaling

Graduation date: 2004This thesis investigates Dynamic Voltage Scaling (DVS) techniques to lower\ud power consumption in video decoding. A DVS scheme called the Frame-data\ud Computation Aware (FDCA) method has been presented. This method is\ud adaptable not only to stored video applications but also to real-time video\ud scenarios. Unlike DVS schemes for video decoding proposed earlier, the FDCA\ud scheme does not require any preprocessing mechanisms. Results from simulations\ud performed using the scheme are presented and compared with prior existing DVS\ud schemes. The results indicate that the FDCA method provides power saving of up\ud to an average of about 68%
