ABSTRACT:
A memory processor which prevents errors when the compiler advances long latency load instructions in the instruction sequence to reduce the loss of efficiency resulting from the latency time. The memory processor intercepts all load and store instructions prior to the instructions entering the memory pipeline. The memory processor stores load instructions for a period of time sufficient to determine if any subsequent store instruction that would have been executed prior to the load instruction, had the load instruction not been moved, references the same address as that specified in the load instruction. If a store instruction references the load instruction address, the invention returns the same data as the load instruction would have if it was not moved by the compiler.
