摘要： A method and apparatus for supporting cache coherency in a multiprocessor computing environment having multiple processing units, each processing unit having a local cache memory associated therewith. A snoop filter device is associated with each processing unit and includes at least one snoop filter primitive implementing filtering method based on usage of stream registers sets and associated stream register comparison logic. From the plurality of stream registers sets, at least one stream register set is active, and at least one stream register set is labeled historic at any point in time. In addition, the snoop filter block is operatively coupled with cache wrap detection logic whereby the content of the active stream register set is switched into a historic stream register set upon the cache wrap condition detection, and the content of at least one active stream register set is reset. Each filter primitive implements stream register comparison logic that determines whether a received snoop request is to be forwarded to the processor or discarded.

摘要： Cache lines in a computing environment with transactional memory are configurable with a coherency mode and are associated with a high-conflict indicator. Cache lines in full-line coherency mode are operated or managed with full-line granularity. Cache lines in sub-line coherency mode are operated or managed as sub-cache line portions of a full cache line. A cache line is placed in sub-line coherency mode based on examining the high-conflict indicator. A transaction accessing a memory address in a cache line in sub-line coherency mode marks only the sub-cache line portion associated with the memory address as transactionally accessed. The high-conflict indicator may be included in a set of descriptive bits associated with the cache line. A copy of the high-conflict indicator for a cache line in a first cache may be updated with the high-conflict indicator for the cache line in a second cache.

摘要： A compare instruction of an instruction set architecture (ISA), when executed tests one or more operands for an instruction defined condition. The result of the test is stored as an operand, with leading zeros, in a general register of the ISA. The general register is identified (explicitly or implicitly) by the compare instruction. Thus, the result of the test can be manipulated by standard register operations of the computer system. In a superscalar processor, no special "condition code" renaming is required, as the standard register renaming takes care of out-of-order processing of the conditions.
摘要翻译：指令集体系结构（ISA）的比较指令在执行时，会针对指令定义的条件测试一个或多个操作数。测试结果作为操作数存储在ISA的通用寄存器中，带有前导零。通用寄存器被比较指令识别（明确或隐含地）。因此，测试的结果可以通过计算机系统的标准寄存器操作来操纵。在超标量处理器中，不需要特殊的“条件代码”重命名，因为标准寄存器重命名可以处理条件的无序处理。
