ABSTRACT:
The present invention is directed to an apparatus and method for sending and receiving instructions, or operations, in an information handling system. The operations are received in a particular, desired order, regardless of the order in which the operations are sent. The invention provides an apparatus and method which assigns a vector to each operation or sub-operation to indicate the desired receiving order of the operations. In addition, the apparatus and method implementing the invention assign a vector to the receiving unit to indicate the order into which the operations should be placed in the receiving unit. The two vectors are manipulated in such a way as to signal which operations should be accepted into which places in the receiving unit. One operation may be mapped to multiple sub-operations in the receiving unit. In addition, the mapping of the sending order of the opcode portion of the operations and the mapping of the sending order of the data portion of the operation are done in parallel, and thus the mapping does not add cycle time delay to the bus transfer time.
