    • 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.
    • 一种信号处理装置,包括通过公共地址总线和公共数据总线相互连接的中央处理块和多个信号处理功能块,其中模拟信号线被提供用于中央处理块和多个信号之间的模拟信号传输 处理功能块和中央处理块设置有连接到模拟信号线的D / A转换器和A / D转换器。 因此,在中央处理块中仅需要D / A转换器和A / D转换器,用于中央处理块和每个处理功能块之间的模拟信号传输。 此外,随着模拟信号线的数量的限制,布线也可以简化。
