Estimating the term…
A computer apparatus incorporating special instructions to force load and store operations to execute in program order. The present invention provides a new and novel store instruction that is suspended until all prior store instructions have been completed by an associated CPU. Also, a new load instruction is provided which blocks any subsequent load instructions from executing until this load instruction has been completed by an associated CPU. These instructions allow for high efficiency computer systems to be implemented which optimize instruction throughput by executing subsequent instructions while waiting for a prior instruction to complete.
A method of ordering load operations performed by a CPU executing a stream of instructions, wherein the stream of instructions are in a program order and include load instructions and store instructions, and the load instructions each perform a load operation, the method comprising:
A method of ordering store operations performed by a CPU executing a stream of instructions, wherein the stream of instructions are in a program order and include load instructions and store instructions and the store instructions each perform a store operation, the method comprising:
A digital computer having an instruction execution means for executing instructions from a stream of instructions, including load and store instructions, wherein the stream of instructions are in a program order, the digital computer comprising:
