Abstract
An information transfer apparatus for transferring memory operand data from a source address in a memory region to a destination address, including a first and second data overlap detecting circuits. If either detecting circuit indicates that data overlap is not present, the data transfer takes place word-by-word. In the case overlap is present, the data is transferred in bytes. The first detecting circuit checks for overlap by comparing the values and identities of predetermined bits in the source address and destination address. The second detecting circuit calculates the difference between the source and destination address and compares this difference to the length of the source operand data to be transferred.
