Digital signal processing apparatus |
摘要 |
A digital signal processing apparatus includes an A/D converter for converting an analog input signal to digital data, a memory having a plurality of memory blocks for storing the digital data, and a processor for processing digital data when read out from the memory. A first controller cyclically stores output digital data from the A/D converter in the blocks in the memory in a predetermined order and outputs the stored data to the processor every time a first command is generated by a first command generator. A second controller inhibits updating of a specific block designated by a second command generator, and outputs the data from the specific block to the processor every time a second command is generated by the second command generator.
