    摘要: A method and structure facilitates the debugging and test coverage capabilities of a microprocessor. A microprocessor having memory arrays, a debug block, and one or more built-in-self-test (BIST) engines is disclosed. The debug block is capable of driving control information out onto a state machine output bus in response to an event and the control information can be selectively used to control signature analysis or recording elements of the microprcessor, such as multiple-input-shift-registers and first-in-first-out devices, that facilitate in the monitoring and debugging of the microprocessor. The signature and recording elements may or may not be contained within the one or more BIST engines and may or may not be used in conjunction with the memory arrays or BIST engine(s) of the microprocessor.

    摘要: A computer apparatus and related method to access storage is provided. In one aspect, a controller maps an address range of a data block of storage into an accessible memory address range of at least one of a plurality of processors, in a further aspect, the controller ensures that copies of the data block cached in a plurality of memories by a plurality of processors are consistent.

    摘要: In a computing system having a plurality of transaction source nodes issuing transactions into a switching fabric, an underserviced node notifies source nodes in the system that it needs additional system bandwidth to timely complete an ongoing transaction. The notified nodes continue to process already started transactions to completion, but stop the introduction of new traffic into the fabric until such time as the underserviced node indicates that it has progressed to a preselected point.
