摘要： A mechanism is provided for thread completion arbitration. The mechanism comprises executing more than two threads of instructions simultaneously in the processor, selecting a first thread from a first subset of threads, in the more than two threads, for completion of execution within the processor, and selecting a second thread from a second subset of threads, in the more than two threads, for completion of execution within the processor. The mechanism further comprises completing execution of the first and second threads by committing results of the execution of the first and second threads to a storage device associated with the processor. At least one of the first subset of threads or the second subset of threads comprise two or more threads from the more than two threads. The first subset of threads and second subset of threads have different threads from one another.

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, and an instruction sequencing unit that fetches instructions for execution by the execution unit. The processor further includes an operand data structure and an address generation accelerator. The operand data structure specifies a first relationship between addresses of sequential accesses within a first address region and a second relationship between addresses of sequential accesses within a second address region. The address generation accelerator computes a first address of a first memory access in the first address region by reference to the first relationship and a second address of a second memory access in the second address region by reference to the second relationship.

摘要： A data processing system has a processor, a memory, and an instruction set architecture (ISA) that includes: (1) an asynchronous memory mover (AMM) store (ST) instruction initiates an asynchronous memory move operation that moves data from a first memory location having a first real address to a second memory location having a second real address by: (a) first performing a move of the data in virtual address space utilizing a source effective address a destination effective address; and (b) when the move is completed, completing a physical move of the data to the second memory location, independent of the processor. The ISA further provides (2) an AMM terminate ST instruction for stopping an ongoing AMM operation before completion of the AMM operation, and (3) a LD CMP instruction for checking a status of an AMM operation.

摘要： A data processing system has an asynchronous memory mover, which includes multiple sets of registers for storing addressing and control parameters utilized to generate one or more asynchronous memory move (AMM) operations. The memory mover detects a receipt of a first set of parameters in a first set of registers from the processor. The processor forwards the parameters after the processor initiates a data move in virtual address space, utilizing a source effective address and a destination effective address. The memory mover responds to receiving the first set of parameters by generating and launching a first asynchronous memory move (AMM) operation. When the memory mover receives a second set of parameters in a second set of registers before the first AMM operation completes, the memory mover generates and launches a second AMM operation concurrently with the first AMM operation if no address conflicts exist.

摘要： While an AMM operation is ongoing, a prefetch request for data from the source effective address or the destination effective address triggers a cache injection by the AMM mover (or memory controller) of relevant data from the stream of data being moved in the physical memory. The memory controller forwards the first prefetched line to the prefetch engine and L1 cache. The memory controller also forwards the next cache lines in the sequence of data to the L2 cache and a subsequent set of cache lines to the L3 cache. The memory controller then forwards the remaining data to the destination memory location. Quick access to prefetch data is enabled by buffering the stream of data in the upper caches rather than placing all the moved data within the memory. Also, the memory controller does not overrun the upper caches, by placing moved data into only a subset of the available cache lines of the upper level cache.
摘要翻译：当AMM操作正在进行时，来自源有效地址或目的地有效地址的数据的预取请求触发AMM移动器（或存储器控制器）从在物理存储器中移动的数据流中的相关数据的高速缓存注入。存储器控制器将第一预取行转发到预取引擎和L1缓存。存储器控制器还将数据序列中的下一个高速缓存行转发到L2高速缓存以及随后的一组高速缓存行到L3高速缓存。存储器控制器然后将剩余的数据转发到目的地存储器位置。通过缓存高速缓存中的数据流，而不是将所有移动的数据放在内存中，可以快速访问预取数据。此外，通过将移动的数据仅放置在高级缓存的可用高速缓存行的一部分中，存储器控制器不会超过上部高速缓存。

摘要： In at least one embodiment, a processor detects during execution of program code whether a load instruction within the program code is associated with a hint. In response to detecting that the load instruction is not associated with a hint, the processor retrieves a full cache line of data from the memory hierarchy into the processor in response to the load instruction. In response to detecting that the load instruction is associated with a hint, a processor retrieves a partial cache line of data into the processor from the memory hierarchy in response to the load instruction.

摘要： Each instruction thread in a SMT processor is associated with a software assigned base input processing priority. Unless some predefined event or circumstance occurs with an instruction being processed or to be processed, the base input processing priorities of the respective threads are used to determine the interleave frequency between the threads according to some instruction interleave rule. However, upon the occurrence of some predefined event or circumstance in the processor related to a particular instruction thread, the base input processing priority of one or more instruction threads is adjusted to produce one more adjusted priority values. The instruction interleave rule is then enforced according to the adjusted priority value or values together with any base input processing priority values that have not been subject to adjustment.
