Abstract: Systems and methods are provided for simplifying load acquire and store release semantics that are used in reduced instruction set computing (RISC). Translating the semantics into micro-operations, or low- level instructions used to implement complex machine instructions, can avoid having to implement complicated new memory operations. Using one or more data memory barrier operations in conjunction with load and store operations can provide sufficient ordering as a data memory barrier ensures that prior instructions are performed and completed before subsequent instructions are executed.

Abstract: A fetch component and an execution component system and method wherein the fetch component is configured for storing a hazard prediction associated with a group of memory access instructions in a buffer associated with branch prediction. The execution component is configured for executing a memory access instruction associated with the group of memory access instructions as a function of the hazard prediction entry.
