ABSTRACT:
A signal processing device including a central processing block and plural signal processing function blocks, which are mutually connected by a common address bus and a common data bus, wherein analog signal lines are provided for analog signal transmission between the central processing block and the plural signal processing function blocks and the central processing block is provided with a D/A converter and an A/D converter connected to the analog signal lines. Thus there are only required a D/A converter and an A/D converter in the central processing block, for analog signal transmission between the central processing block and each of the processing function blocks. Also the wiring can be simplified as the number of analog signal lines is limited.
