The power consumption by the data cache is important in DSP designs. This study presents an enhanced branch access LRU-SEQ (EBA-LRU-SEQ) policy for data caches in DSP designs to reduce the power consumption. The design is based on the LRU policy with embedded prefetch table to provide branch access. Tests show that the EBA-LRU-SEQ policy reduces the data cache power consumption to 54% of a system with no power control.
