Synchronizing memory copy operations with memory accesses

A system comprising:

• an unordered interconnect;
• and
• at least two components coupled to the interconnect, at least two of the at least two components including:
• a comparator to compare an incoming memory address with a memory address currently being copied by a memory copy operation;
• and
• a holding buffer to hold the incoming address prior to forwarding it to a memory read/write queue if the incoming memory address is the same as the memory address currently being copied by the memory copy operation, and to forward the buffered incoming memory address to the read/write queue once the memory copy operation for the memory address currently being copied has finished.

A method comprising:

• comparing an incoming memory address with a memory address currently being copied by a memory copy operation;
• holding the incoming address prior to forwarding it to a memory read/write queue if the incoming memory address is the same as the memory address currently being copied by the memory copy operation;
• and
• forwarding the incoming memory address to the read/write queue once the memory copy operation for the memory address currently being copied has finished.

An article comprising a computer readable medium having instructions thereon which when executed cause a computer to:

• compare an incoming memory address with a memory address currently being copied by a memory copy operation;
• hold the incoming address prior to forwarding it to a memory read/write queue if the incoming memory address is the same as the memory address currently being copied by the memory copy operation;
• and
• forward the incoming memory address to the read/write queue once the memory copy operation for the memory address currently being copied has finished.
