Abstract:
1. A data conversion processing apparatus that resamples data from an input section and outputs that data to an output section, said data conversion processing apparatus comprising: a resampling section that samples and outputs input data at different frequencies; a memory that stores data output by said resampling section; and a direct memory access unit that performs control so that data input from said input section is output to said resampling section via an input channel and output channel, and also data stored in said memory is transferred to said output section via an output channel and input channel, wherein: said resampling section and said memory are provided as a plurality correspondingly; and said direct memory access unit connects part of a plurality of input channels to respective outputs of said plurality of memories, connects part of a plurality of output channels to respective inputs of said plurality of resampling sections and performs control so that data from said plurality of input sections are output to said plurality of resampling sections via corresponding said input channel and output channel, and data stored in said plurality of memories are transferred to said plurality of output sections via corresponding said output channel and input channel.
