摘要： Systems and methods are disclosed for aligning data in memory access and other applications. In one embodiment a system is provided that includes a memory unit, a shifter, and control logic operable to route data from the memory unit to the shifter and to send an indication to the shifter of an amount by which the data is to be shifted. In one embodiment, the control logic provides support for speculative execution. The control logic may also permit multiplexing of big endian and little endian data alignment operations, and/or multiplexing of data alignment operations with non-data alignment operations. In one embodiment, the memory unit, shifter, and control logic are integrated within a processing unit, such as a microengine in a network processor.

摘要： A method according to one embodiment may include performing one or more fetch operations to retrieve one or more instructions from a program memory; scheduling a write instruction to write data from at least one data register into the program memory; and stealing one or more cycles from one or more of the fetch operations to write the data in the at least one data register into the program memory. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

摘要： A branch aware first-in first-out (FIFO) memory may include a memory array to store data; a push pointer to address memory locations therein to write data; a pop pointer to address memory locations therein to read data; a pointer memory; and control logic coupled to the pointer memory. The pointer memory saves prior pop pointer values of the pop pointer. The control logic may restore prior pop pointer values from the pointer memory into the pop pointer in response to receiving program branching information.

摘要： In an embodiment, a shared memory fabric is configured to receive memory requests from multiple agents, where at least some of the requests have an associated order identifier and a deadline value to indicate a maximum latency prior to completion of the memory request. Responsive to the requests, the fabric is to arbitrate between the requests based at least in part on the deadline values. Other embodiments are described and claimed.

摘要： In one embodiment, a conflict detection logic is configured to receive a plurality of memory requests from an arbiter of a coherent fabric of a system on a chip (SoC). The conflict detection logic includes snoop filter logic to downgrade a first snooped memory request for a first address to an unsnooped memory request when an indicator associated with the first address indicates that the coherent fabric has control of the first address. Other embodiments are described and claimed.
