Abstract: An instruction in a first cache line may be identified and an address associated with the instruction may be determined. The address may be determined to cross a cache line boundary associated with the first cache line and a second cache line. In response to determining that the address crosses the cache line boundary, the instruction may be adjusted based on a portion of the address included in the first cache line and a second instruction may be created based on a portion of the address included in the second cache line. The second instruction may be injected into an instruction pipeline after the adjusted instruction.

Abstract: In one embodiment, a processor includes a frontend unit having an instruction decoder to receive and to decode instructions of a plurality of threads, an execution unit coupled to the instruction decoder to receive and execute the decoded instructions, and an instruction retirement unit having a retirement logic to receive the instructions from the execution unit and to retire the instructions associated with one or more of the threads that have an instruction or an event pending to be retired. The instruction retirement unit includes a thread arbitration logic to select one of the threads at a time and to dispatch the selected thread to the retirement logic for retirement processing.

Abstract: Exemplary aspects are directed toward resolving fault suppression in hardware, which at the same time does not incur a performance hit. For example, when multiple instructions are executing simultaneously, a mask can specify which elements need not be executed. If the mask is disabled, those elements do not need to be executed. A determination is then made as to whether a fault happens in one of the elements that have been disabled. If there is a fault in one of the elements that has been disabled, a state machine re-fetches the instructions in a special mode. More specifically, the state machine determines if the fault is on a disabled element, and if the fault is on a disabled element, then the state machine specifies that the fault should be ignored. If during the first execution there was no mask, if there is an error present during execution, then the element is re-run with the mask to see if the error is a “real” fault.
