Since process technology has been in deep sub-micron era, leakage power dissipation is one of major concerns, and its reduction is an essential issue in VSLI design. Body Biasing and Power Gating are well known techniques to save leakage power in standby-time. However, in run-time, its large overhead energy consumption and large latency for sleep control prevent a circuit from saving leakage power in short idle times. Recently, to achieve leakage saving in short idle times, advanced PG and BB using shallow depth sleep which provides smaller overheads than the conventional deep sleep are studied. A shallower sleep provides smaller overheads. Meanwhile, a shallow sleep has less leakage saving efficiency than a deeper sleep. Thus, the decision of sleep depth is highly-influential issue for total leakage power saving. We propose the circuit having multiple sleep modes which are capable of reconfiguring those depths. Proposed circuit achieves good leakage saving by adopting those depths with run-time factors, i.e. running application and temperature. In addition, we propose the sleep mode controlling method for our circuit. This method assigns optimal sleep mode for idle times in run-time by assessing those lengths. |
