    摘要: An apparatus and method for prefetching cache data in response to data requests. The prefetching uses the memory addresses of requested data to search for other data, from a related address, in a cache. This, or other data, may then be prefetched based on the result of the search.

    摘要: An embodiment of the invention is directed at a bridge having an outbound pipe for buffering transaction information and data being transported from various devices to a bus. The bridge has an arbiter for granting requests associated with these devices to access the outbound pipe for transferring the transaction information and data into the pipe. The bridge generates a reject signal in response to an initial request associated with an initial transaction from a first one of the devices if the outbound pipe is unavailable to accept further transaction information or data. The bridge has response control logic for generating a retry response for the initial transaction in response to the reject signal. The bridge is able to assert a stamp signal in response to the reject signal. The arbiter in response to the stamp being asserted waits, without granting any other lower priority requests to access the outbound pipe, until a subsequent transaction from the first device makes progress.

    摘要: A circuit for controlling interrupt request signal transmission in a computer system. An input receives an interrupt request from an external component. First circuitry coupled to the input generates a signal in response to the interrupt request from the external component. The signal causes a processor to switch to fully operational mode. Second circuitry coupled to the input generates an interrupt request signal to the processor in response to the interrupt request from the external component. A signal processing circuit coupled to the second circuitry suppresses transmission of the interrupt request signal to the processor until the signal is transmitted to the processor.
