    Abstract: A pipelined processing device includes: a pipeline controller configured to receive at least one instruction associated with an operation from each of a plurality of subcontrollers, and input the at least one instruction into a pipeline; and a pipeline counter configured to receive an active time value from each of the plurality of subcontrollers, the active time value indicating at least a portion of a time taken to process the at least one instruction, the pipeline controller configured to route the active time value to a shared pipeline storage for performance analysis.

    Abstract: To facilitate an efficient processing of contended cache lines, a cache controller that is associated with a requestor receives a fetch request for data from the requestor. The fetch request is associated with a cache scope designation. If the data is in a high-level cache (e.g., L1 cache) associated with the requestor, the cache controller returns the requested data to the requestor. If the data is not in the high-level cache or if the data is not within the cache pool identified by the cache scope of search designation, and/or if obtaining the data is contentious, the controller returns a cache miss, undeliverable data, and request done instruction to the requestor. Such scheme allows or permits address contention events when the requestor deems such events are necessary and/or when important. As such, address contention events, performance, latencies, increased executions times, inefficient use of resources, may be diminished.
