  • Speculative code motion for memory latency hiding
    Patent number: 7752611
    Abstract: Various embodiments that may be used in performing speculative code motion for memory latency hiding are disclosed. One embodiment comprises extracting an asynchronous signal from a memory access instruction in a program to represent a latency of the memory access instruction, and generating a wait instruction to wait the asynchronous signal.

  • Latency hiding of traces using block coloring
    Publication number: 20090265530
    Abstract: An embodiment of the present invention is a technique to hide latency in program traces. Blocks of instructions between start and end of a critical section are associated with color information. The blocks correspond to a program trace and containing a wait instruction. The wait instruction is sunk down the blocks globally to the end of the critical section using the color information and a dependence constraint on the wait instruction.
