摘要： An example system on a chip (SoC) includes a processor, a cache, and a main memory. The SoC can include a first memory to store data in a memory line, wherein the memory line is set to an invalid state. The processor can include a processor coupled to the first memory. The processor can determine that a data size of a first data set received from an application is within a data size range. The processor can determine that an aggregate data size of the first data set and a second data set received from the application is at least a same data size as data size of the memory line. The processor can perform an invalid-to-modify (I2M) operation to change the memory line from the invalid state to a modified state. The processor can write the first data set and the second data set to the memory line.

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.
