Abstract:
A timing generator for an imaging system, characterized by:a line control unit configured to generate a first timing waveform for line read out of image data from an image sensor; a frame control unit coupled to the line control unit and configured to generate a second timing waveform for frame read out of image data from an image sensor, the frame control unit including a next frame control word register and a current frame control word register, the next frame control word register to buffer a next frame control word, the current frame control word register to buffer a current frame control word; a clock generator configured to provide a clock signal to the line control unit; a request arbitrator configured to arbitrate timing requests between the line control unit and the frame control unit based on an input; and a control word memory coupled to the request arbitrator and configured to provide a line control word to the line control unit or a frame control word to the frame control unit depending on an output from the request arbitrator, the line control word and the frame control word to control the first timing waveform and the second timing waveform, respectively, wherein the next frame control word register and the current frame control word register provide the input.
