Process Variations Tolerant - Low Power Design of DSP blocks

 Develop techniques for the design of low power and process tolerant

         systems.  Application to Color Interpolation Filtering

               (ICCAD ‘07, TCAD‘09), Discrete Cosine Transform-

                                  DCT (DATE ‘07, TVLSI ‘09),

                               Motion Estimation (ISLPED ‘09)

Algorithm/Architecture Co-Optimization for Low Power Design

Develop optimization techniques for  Low Power Design. Application to FIR filtering (ICASSP ‘07) 

        Low Power - Error Resilient

               Execution Units

 Avoid possible delay failures in

the critical paths by dynamically stretching the clock period. This allows circuits to operate at scaled supply with minimal performance degradation.
