摘要： A set of helper thread binaries is created to retrieve data used by a set of main thread binaries. The set of helper thread binaries and the set of main thread binaries are partitioned according to common instruction boundaries. As a first partition in the set of main thread binaries executes within a first core, a second partition in the set of helper thread binaries executes within a second core, thus “warming up” the cache in the second core. When the first partition of the main completes execution, a second partition of the main core moves to the second core, and executes using the warmed up cache in the second core.

摘要： A set of helper thread binaries is created to retrieve data used by a set of main thread binaries. If executing a portion of the set of helper thread binaries results in the retrieval of data needed by the set of main thread binaries, then that retrieved data is utilized by the set of main thread binaries.

摘要： A set of helper thread binaries is created from a set of main thread binaries. The helper thread monitors software or hardware ports for incoming data events. When the helper thread detects an incoming event, the helper thread asynchronously executes instructions that calculate incoming data needed by the main thread.

摘要： A clone set of General Purpose Registers (GPRs) is created to be used by a set of helper thread binaries, which is created from a set of main thread binaries. When the set of main thread binaries enters a wait state, the set of helper thread binaries uses the clone set of GPRs to continue using unused execution units within a processor core. The set of helper threads are thus able to warm up local cache memory with data that will be needed when execution of the set of main thread binaries resumes.

摘要： A method and a data processing system by which population count (popcount) operations are efficiently performed without incurring the latency and loss of critical processing cycles and bandwidth of real time processing. The method comprises: identifying data to be stored to memory for which a popcount may need to be determined; speculatively performing a popcount operation on the data as a background process of the processor while the data is being stored to memory; storing the data to a first memory location; and storing a value of the popcount generated by the popcount operation within a second memory location. The method further comprises: determining a size of data; determining a granular level at which the popcount operation on the data will be performed; and reserving a size of said second memory location that is sufficiently large to hold the value of the popcount.

摘要： A processor includes at least one execution unit that executes instructions, at least one register file, coupled to the at least one execution unit, that buffers operands for access by the at least one execution unit, an instruction sequencing unit that fetches instructions for execution by the at least one execution unit, and an address generation accelerator. The address generation accelerator, responsive to an initiation signal received from the instruction sequencing unit, computes and outputs first and second effective addresses of operands of an operation.
