摘要： In an embodiment, a memory management unit (MMU) is configured to retain a block of data that includes multiple page table entries. The MMU is configured to check the block in response to TLB misses, and to supply a translation from the block if the translation is found in the block without generating a memory read for the translation. In some embodiments, the MMU may also maintain a history of the TLB misses that have used translations from the block, and may generate a prefetch of a second block based on the history. For example, the history may be a list of the most recently used Q page table entries, and the history may show a pattern of access that are nearing an end of the block. In another embodiment, the history may comprise a count of the number of page table entries in the block that have been used.

摘要： In an embodiment, a non-transparent memory unit is provided which includes a non-transparent memory and a control circuit. The control circuit may manage the non-transparent memory as a set of non-transparent memory blocks. Software executing on one or more processors may request a non-transparent memory block in which to process data. The control circuit may allocate a first block, and may return an address (or other indication) of the allocated block so that the software can access the block. The control circuit may also provide automatic data movement between the non-transparent memory and a main memory system to which the non-transparent memory unit is coupled. For example, the automatic data movement may include filling data from the main memory system to the allocated block, or flushing the data in the allocated block to the main memory system after the processing of the allocated block is complete.

摘要翻译：在一个实施例中，提供了一种非透明存储器单元，其包括非透明存储器和控制电路。控制电路可以将非透明存储器作为一组非透明存储器块来管理。在一个或多个处理器上执行的软件可以请求处理数据的非透明存储器块。控制电路可以分配第一块，并且可以返回所分配的块的地址（或其他指示），使得软件可以访问块。控制电路还可以在非透明存储器与非透明存储器单元耦合到的主存储器系统之间提供自动数据移动。例如，自动数据移动可以包括在分配的块的处理完成之后从主存储器系统填充数据到所分配的块，或者将分配的块中的数据刷新到主存储器系统。

摘要： In one embodiment, a receiver on a credit-based flow-controlled interface is configured to free one or more data credits early when a data payload is received that incurs fewer unused data credits within a buffer memory that is allocated at a coarser granularity than the data credits. In another embodiment, header credits and data credits are dynamically adjusted based on actual packet data payload sizes.
