Data transfer apparatus and data transfer method

摘要

In a data transfer apparatus, an operation cycle number required to transfer data is reduced. Since data transfer control means 110 is provided which controls access timing with respect to a transfer source and a transfer destination based upon transfer latency information 591 and 592, data outputted from a transfer source device 121 is directly acquired to a transfer destination device 122. As a result, data transfer time can be omitted which is required to temporarily store data into a data buffer, and since the data buffer is omitted, a circuit scale can be reduced and also data transfer time can be shortened.
