Abstract
A device protects data dependency for memory access. The device includes a memory and a processor. The processor executes memory access instructions including load instructions and store instructions. The processor includes load circuitry to execute the load instructions; and store circuitry to execute the store instructions. Each memory access instruction includes a token index field containing a token index that associates the memory access instruction with a memory location. The processor further includes dispatch circuitry to dispatch instructions to the load circuitry and the store circuitry; and a token registry to record used token indices according to token index fields in the memory access instructions dispatched by the dispatch circuitry.
