prior to the load operation requested by the ordered load
instruction being completed by the CPU.
4. A method of ordering store operations performed by a
CPU executing a stream instruction, 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:
detecting an ordered store instruction in the stream of
instructions;
preventing the CPU from executing the ordered store
instruction before the store operations requested by all store
instructions preceding in the program order the ordered store
operation are completed by the CPU and;
allowing the CPU to execute a store instruction
subsequent in the program order to the ordered store
instruction prior to the store operation requested by the
ordered store instruction being completed by the CPU.
7. 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:
detection means for detecting an ordered store or an
ordered load instruction in the stream of instructions; and
control means, connected with the detection means, to
control the instruction execution means as follows:
if an ordered load instruction is detected, the
control means controls the instruction execution means
such that a load instruction subsequent in the
program order to the ordered load instruction is not
executed prior
