Abstract
Systems and method are directed to reducing power consumption of data transfer between a processor and a memory. A data to be transferred on a data bus between the processor and the memory is checked for a first data pattern, and if the first data pattern is present, transfer of the first data pattern is suppressed on the data bus. Instead, a first address corresponding to the first data pattern is transferred on a second bus between the processor and the memory. The first address is smaller than the first data pattern. The processor comprises a processor-side first-in-first-out (FIFO) and the memory comprises a memory-side FIFO, wherein the first data pattern is present at the first address in the processor-side FIFO and at the first address in the memory-side FIFO.
