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： In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing a balanced P-LRU tree for a “multiple of 3” number of ways cache. For example, in one embodiment, such means may include an integrated circuit having a cache and a plurality of ways. In such an embodiment the plurality of ways include a quantity that is a multiple of three and not a power of two, and further in which the plurality of ways are organized into a plurality of pairs. In such an embodiment, means further include a single bit for each of the plurality of pairs, in which each single bit is to operate as an intermediate level decision node representing the associated pair of ways and a root level decision node having exactly two individual bits to point to one of the single bits to operate as the intermediate level decision nodes representing an associated pair of ways. In this exemplary embodiment, the total number of bits is N−1, wherein N is the total number of ways in the plurality of ways. Alternative structures are also presented for full LRU implementation, a “multiple of 5” number of cache ways, and variations of the “multiple of 3” number of cache ways.

摘要： A method and apparatus for avoiding live-lock during transaction execution is herein described. Counting logic is utilized to track successfully committed transactions for each processing element. When a data conflict is detected between transactions on multiple processing elements, priority is provided to the processing element with the lower counting logic value. Furthermore, if the values are the same, then the processing element with the lower identification value is given priority, i.e. allowed to continue while the other transaction is aborted. To avoid live-lock between processing elements that both have predetermined counting logic values, such as maximum counting values, when one processing element reaches the predetermined counting value all counters are reset. In addition, a failure at maximum value (FMV) counter may be provided to count a number of aborts of a transaction when counting logic is at a maximum value. When the FMV counter is at a predetermined number of aborts the counting logic is reset to avoid live lock.
摘要翻译：这里描述了用于在事务执行期间避免实时锁定的方法和装置。计数逻辑用于跟踪每个处理元素的成功提交事务。当在多个处理元件之间的事务之间检测到数据冲突时，以较低的计数逻辑值提供给处理元件的优先级。此外，如果值相同，则具有较低识别值的处理元件被赋予优先级，即允许在其他事务被中止时继续。为了避免在具有预定的计数逻辑值（例如最大计数值）的处理元件之间的实时锁定，当一个处理元件达到预定计数值时，所有计数器都被重置。此外，当计数逻辑处于最大值时，可以提供在最大值（FMV）计数器上的故障来计数事务的中止次数。当FMV计数器处于预定数量的中止时，计数逻辑被复位以避免实时锁定。
