摘要： In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing efficient communication between caches in hierarchical caching design. For example, in one embodiment, such means may include an integrated circuit having a data bus; a lower level cache communicably interfaced with the data bus; a higher level cache communicably interfaced with the data bus; one or more data buffers and one or more dataless buffers. The data buffers in such an embodiment being communicably interfaced with the data bus, and each of the one or more data buffers having a buffer memory to buffer a full cache line, one or more control bits to indicate state of the respective data buffer, and an address associated with the full cache line. The dataless buffers in such an embodiment being incapable of storing a full cache line and having one or more control bits to indicate state of the respective dataless buffer and an address for an inter-cache transfer line associated with the respective dataless buffer. In such an embodiment, inter-cache transfer logic is to request the inter-cache transfer line from the higher level cache via the data bus and is to further write the inter-cache transfer line into the lower level cache from the data bus.

摘要： A method and apparatus for optimizing an Unbounded Transactional Memory (UTM) system is herein described. Hardware support for monitors, buffering, and metadata is provided, where orthogonal metaphysical address spaces for metadata may be separate associated with threads and/or software subsystems within threads. In addition, the metadata may be held with hardware in a compressed manner with regard to data transparently to software. Furthermore, in response to metadata access instruction/operations the hardware is capable of supporting a forced metadata value to enable multiple modes of transactional execution. However, if monitors, buffered data, metadata, or other information is lost or conflicts are detected hardware provides for variations of a loss instruction that is able to poll a transaction status register for such loss or conflict and jump execution to a label in response to detecting the loss or conflict. Similarly, multiple variations of a commit instruction are provided for to allow software to define commit conditions and information to clear upon commit. Furthermore, hardware provides support to enable suspension and resume of transactions upon ring level transitions.

摘要： A method and apparatus for providing a memory model for hardware attributes to support transactional execution is herein described. Upon encountering a load of a hardware attribute, such as a test monitor operation to load a read monitor, write monitor, or buffering attribute, a fault is issued in response to a loss field indicating the hardware attribute has been lost. Furthermore, dependency actions, such as blocking and forwarding, are provided for the attribute access operations based on address dependency and access type dependency. As a result, different scenarios for attribute loss and testing thereof are allowed and restricted in a memory model.
摘要翻译：这里描述了一种用于提供硬件属性的存储器模型以支持事务执行的方法和设备。在遇到加载硬件属性（例如加载读取监视器，写入监视器或缓冲属性的测试监视器操作）时，响应指示硬件属性已丢失的丢失字段而发出故障。此外，基于地址依赖性和访问类型依赖性，为属性访问操作提供诸如阻塞和转发之类的依赖性动作。因此，属性丢失和测试的不同场景被允许并限制在内存模型中。
