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： A system for using a plurality of heterogeneous processors in a common computer system is presented. Each processor type in the heterogeneous group handles a particular instruction set. The processors share a common memory using a common bus. In one embodiment, one of the processor types accesses the memory using DMA instructions. In another embodiment, a cache for each type of processor is stored in the common memory pool. In one embodiment, one or more PowerPC processors shares a memory with one or more Synergistic Processing Complex (SPC). A common table is used to track and maintain memory for the various processors.

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.

摘要： A system and method for executing instructions utilizing a preferred slot alignment mechanism is presented. A processor architecture uses a vector register file, a shared data path, and instruction execution logic to process both single instruction multiple data (SIMD) instruction and scalar instructions. The processor architecture divides a vector into four “slots,” each including four bytes, and locates scalar data in “preferred slots” to ensure proper positioning. Instructions using the preferred slot mechanism include 1) shift and rotate instructions operating across an entire quad-word that specify a shift amount, 2) memory load and store instructions that require an address, and 3) branch instructions that use the preferred slot for branch conditions (conditional branches) and branch addresses (register-indirect branches). As a result, the processor architecture eliminates the requirement for separate issue slots, separate pipelines, and the control complexity for separate scalar units.

摘要： Disclosed is a procedure or design approach for functional modules that may be used in connection with a multiprocessor integrated circuit chip. The approach includes keeping the dimensions of each module substantially the same and having the bus, power, clock and I/O connection configured the same on all modules. Further requirements for ease of use are to generalize the capability of each module as much as possible and to decentralize functions such as testing to be primarily performed within each module. The use of such considerations or rules substantially eases the design of a given type of custom chips, and based upon an initial chip design greatly facilitates the design of further custom chips, similar in application, but subsequent to the successful completion of the initial chip. The standardization modules and replication of the modules on a given chip also reduces physical verification time in initial chip design as well as redesign time of the initial chip when requirements for chip capability are redefined or otherwise changed. Any subsequent or further custom chips can include more or less of specific modules based upon already established parameters.
