    摘要: The present invention provides for controlling the power consumption of an element. A first power control command is issued by software for the element. It is determined if the power control command corresponds to an allowable power control state for that element as defined by the hardware. If the power control command is not an allowable power control state for that element, the hardware sets the power control at a higher level than the power control state issued by the software. The software is real time software, and the software also sets minimally acceptable activity control states. A hierarchy of power consumption is defined for different elements of a chip by software, which provides the minimum level of power consumption by any element or sub-element on a chip.

    摘要: Disclosed is a coherent cache system that operates in conjunction with non-homogeneous processing units. A set of processing units of a first configuration has conventional cache and directly accesses common or shared system physical and virtual address memory through the use of a conventional MMU (Memory Management Unit). Additional processors of a different configuration and/or other devices that need to access system memory are configured to store accessed data in compatible caches. Each of the caches is compatible with a given protocol coherent memory management bus interspersed between the caches and the system memory.
