ABSTRACT:
The programmable function controller herein may be used in conjunction with a data processor and a waveform storage memory together with digital-to-analog conversion means for providing an analog waveform based on stored digital representations of the waveform in the memory. The function controller includes a plurality of registers which are initially preloaded prior to waveform generation with programmed parameter control words respecting the manner in which the waveform is to be generated. These control words are used to control logic circuitry for selecting a clock to be used by the controller for interrogating the memory to obtain the data words therefrom in a sequence representing data points on the waveform to be generated. The controller then outputs these data words to a digital-to-analog converter for providing the analog version of the waveform.
