Selective power-down for high performance CPU/system

摘要: A microelectronic device according to the present invention is made up of two or more functional units, which are all disposed on a single chip, die. The works strategy that units die not, and do not need be operational at given time in execution computer program controlling device. very rapid basis (typically half clock cycle), therefore, turns off accordance with requirements being executed. This power down can achieved by one three techniques; turning inputs interrupting supply deactivating input signals units. operation results significant reduction consumption corresponding heat dissipation as compared conventional approach keeping time.
