    摘要: In various embodiments, the present invention includes a method for receiving a transaction having first header information from a first peer device at a first agent of a coherent system, inserting second header information onto the transaction, and routing the transaction to a second peer device using the second header information. In one such embodiment, the first header may be a header of a first protocol and the second header may be of a different protocol that is used to tunnel the transaction through the coherent system.

    摘要: A method and apparatus for reducing flow control and minimizing interface acquisition latency in a hub interface is a method of transferring data between a control hub coupled to a hub interface which is coupled to an input-output hub including the following: Transferring the data in packets. Prioritizing isochronous transfers over asynchronous transfers. Limiting asynchronous transfers to 32 bytes per packet when an agent requests the hub interface, and limiting asynchronous transfers to 64 bytes per packet when no requests for the hub interface are recognized.

    摘要: A method and apparatus for throttling high priority memory accesses. An apparatus of the present invention includes an arbiter circuit and a throttling circuit. The arbiter circuit is coupled to receive first and second types of memory access commands and has a preference for the first type of memory access commands. The throttling circuit is coupled to the arbiter and can at least temporarily reduce the preference for the memory access commands of the first type.

    摘要: Error correction circuitry attempts to detect and correct on the fly erroneous words within random access memory (RAM) within a computer system. RAM errors are scrubbed or corrected back in the memory without delaying the memory access cycle. Rather, the address of the section or row of RAM that contains the correctable error is latched for later used by an interrupt-driven firmware memory-error scrub routine. This routine reads and rewrites each word within the indicated memory section--the erroneous word is read, corrected on-the-fly as it is read, and then rewritten back into memory correctly. If the size of the memory section exceeds a predetermined threshold, then the process of reading and re-writing that section is divided into smaller sub-processes that are distributed in time using a delayed interrupt mechanism. Duration of each memory scrubbing subprocess is kept short enough that the response time of the computer system is not impaired with the housekeeping task of scrubbing RAM memory errors. System management interrupts and firmware may be used to implement the memory-error scrub routine, which makes it independent of and transparent to the various operating systems that may be run on the computer system.
