Low-power is of great importance to modern ASIC design. There are some methods for data path power saving in high-level design, but there are not so many for controller. In this article, we give two efficient low-power control code generation criteria to optimize 'X' value and to minimize the total Hamming distance between the consecutive control vectors in high-level controller design. Both of the two criteria can be used in the high level synthesis tools or applied to ASIC designers while generating controller.
