Abstract
A data transfer circuit includes a write circuit to control writing of write data to a memory, a read circuit to control reading of data from the memory, a first circuit to register a store position in the memory at which data written to the memory is stored, and a second circuit to store a data pattern when the write data is comprised of repeated patterns each identical to the data pattern, wherein the write circuit does not register the store position in the first circuit with respect to the written data that is comprised of the repeated patterns each identical to the data pattern stored in the second circuit, and the read circuit reads the data pattern from the second circuit for provision to a source issuing a read request when data requested by the read request corresponds to the data pattern stored in the second circuit.
