Publication number: 20070258305Abstract: A system, method and program product for determining a relative amount of usage of a data retaining device are disclosed. A charge storing device is coupled to a data retaining device in a manner that a use of the data retaining device triggers a charging of the charge storing device. In a period that the data retaining device idles, charges in the charge storing device decay due to natural means. As such, a potential of the charge storing device may be used to indicate an amount of usage of the data retaining device. A comparison of the potentials of two charge storing devices coupled one-to-one to two data retaining devices may be used as a basis to determine a relative amount of usage of each of the two data retaining devices comparing to the other.Type: ApplicationFiled: April 13, 2006Publication date: November 8, 2007Inventors: Kerry Bernstein, Kenneth Goodnow, Clarence Ogilvie, Sebastian Ventrone, Keith Williams

Publication number: 20070255970Abstract: An integrated circuit (IC) chip containing a plurality of voltage islands containing corresponding functional blocks that can be selectively fenced, i.e., powered down, while saving the states of the corresponding inputs, and unfenced in order to manage power consumption of the chip. Each fencable functional block includes a power switch and state-saving circuitry for saving the state of the inputs to that functional block. A power modulation unit (PMU) generates fencing signals that control the power switches and state-saving circuitries so as to selectively fence the corresponding functional blocks.
