The original idea to do this came as a result of extrapolating this trend to add custom processing features to general purpose processing microprocessors in the form of SOCs. If you extrapolate out from the SOC, over time, the role of the microprocessor becomes less and less significant and that of the special function circuits more so. Khitchdee's approach was to start at the other end of the continuum.
