摘要:
Dynamic re-allocation of cache buffer slots includes moving data out of a reserved buffer slot upon detecting an error in the reserved buffer slot, creating a new buffer slot, and storing the data moved out of the reserved buffer slot in the new buffer slot.

A pipelined processing device includes: a processor configured to receive a request to perform an operation; a plurality of processing controllers configured to receive at least one instruction associated with the operation, each of the plurality of processing controllers including a memory to store at least one instruction therein; a pipeline processor configured to receive and process the at least one instruction, the pipeline processor including shared error detection logic configured to detect a parity error in the at least one instruction as the at least one instruction is processed in a pipeline and generate an error signal; and a pipeline bus connected to each of the plurality of processing controllers and configured to communicate the error signal from the error detection logic.

A method of managing a temporary memory includes: receiving a request to transfer data from a source location to a destination location, the data transfer request associated with an operation to be performed, the operation selected from an input into an intermediate temporary memory and an output; checking a two-state indicator associated with the temporary memory, the two-state indicator having a first state indicating that an immediately preceding operation on the temporary memory was an input to the temporary memory and a second state indicating that the immediately preceding operation was an output from the temporary memory; and performing the operation responsive to one of: the operation being an input operation and the two-state indicator being in the second state, indicating that the immediately preceding operation was an output; and the operation being an output operation and the two-state indicator being in the first state, indicating that the immediately preceding operation was an input.

摘要:
A computer-implemented method for managing data transfer in a multi-level memory hierarchy that includes receiving a fetch request for allocation of data in a higher level memory, determining whether a data bus between the higher level memory and a lower level memory is available, bypassing an intervening memory between the higher level memory and the lower level memory when it is determined that the data bus is available, and transferring the requested data directly from the higher level memory to the lower level memory.

摘要:
An apparatus for controlling access to a resource includes a shared pipeline configured to communicate with the resource, a plurality of command queues configured to form instructions for the shared pipeline and an arbiter coupled between the shared pipeline and the plurality of command queues configured to grant access to the shared pipeline to a one of the plurality of command queues based on a first priority scheme in a first operating mode. The apparatus also includes interface logic coupled to the arbiter and configured to determine that contention for access to the resource exists among the plurality of command queues and to cause the arbiter to grant access to the shared pipeline based on a second priority scheme in second operating mode.
