Data conversion processing apparatus

Abstract

A data conversion processing apparatus that makes possible flexible and multifunctional resampling processing using the general-purpose setting method of DMA setting. In the data conversion processing apparatus, when a CPU 10 sets parameters such as input channel information and output channel information including an address for identifying each channel, the transfer amount, and so forth, for a DMA 5, DMA 5 performs data transfer via an input channel and output channel in accordance with the parameters specified by CPU 10. For example, by means of these parameter settings, transfer from a first input section 30 to a resampling section 2 via DMA 5 can be specified, and also transfer of those transfer contents from memory 1 to a first output section 40 can be specified, and transfer from first input section 30 to first output section 40 is performed by means of these two DMA transfers.
