    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: The present invention provides a method for a processor to write data to a cache or other fast memory, without also writing it to main memory. Further, the data is “locked” into the cache or other fast memory until it is loaded for use. Data remains in the locking cache until it is specifically overwritten under software control. The locking cache or other fast memory can be used as additional system memory. In an embodiment of the invention, the locking cache is one or more sets of ways, but not all of the sets or ways, of a multiple set associative cache.

In an embodiment of the invention, a processor can write data to the cache or other fast memory without also writing it to main memory.

    摘要: A system and method for communicating instructions and data between a processor and external devices are provided. The system and method make use of a channel interface as the primary mechanism for communicating between the processor and a memory flow controller. The channel interface provides channels for communicating with processor facilities, memory flow control facilities, machine state registers, and external processor interrupt facilities, for example. These channels may be designated as blocking or non-blocking. With blocking channels, when no data is available to be read from the corresponding registers, or there is no space available to write to the corresponding registers, the processor is placed in a low power “stall” state. The processor is automatically awakened, via communication across the blocking channel, when data becomes available or space is freed. Thus, the channels of the present invention permit the processor to stay in a low power state.

    摘要: A component of a microprocessor-based data processing system, which includes features for regulating power consumption in snoopable components and has gating off memory coherency properties, is determined to be in a relatively inactive state and is transitioned to a non-snoopable low power mode. Then, when a snoop request occurs, a retry protocol is sent in response to the snoop request. In conjunction with the retry protocol, a signal is sent to bring the component into snoopable mode. When the retry snoop is requested, the component is in full power mode and can properly respond to the snoop request. After the snoop request has been satisfied, the component again enters into a low power mode. Therefore, the component is able to enter into a low power mode in between snoops

    摘要: A system and method for communicating command parameters between a processor and a memory flow controller are provided. The system and method make use of a channel interface as the primary mechanism for communicating between the processor and a memory flow controller. The channel interface provides channels for communicating with processor facilities, memory flow control facilities, machine state registers, and external processor interrupt facilities, for example.

With blocking channels, when no data is available to be read from the corresponding registers, or there is no space available to write to the corresponding registers, the processor is placed in a low power “stall” state. The processor is automatically awakened, via communication across the blocking channel, when data becomes available or space is freed. Thus, the channels of the present invention permit the processor to stay in a low power state.

    摘要: The present invention provides for managing an atomic facility cache write back state machine. A first write back selection is made. A reservation pointer pointing to the reserved line in the atomic facility data array is established. A next write back selection is made. An entry for the reservation point for the next write back selection is removed, whereby the valid reservation line is precluded form being selected for the write back. This prevents a modified command from being invalidated.
