Systems and methods for asymmetric image splitter clock generation
Described herein are systems and methods that provide for asymmetric image splitter image stream applications. In one embodiment, a system supporting image multi-streaming comprises an asymmetric image splitter engine that splits super-frame image streams into two or more image streams and a fractional clock divider circuit. The fractional clock divider may comprise a digital feedback control loop and a one-bit sigma delta modulator. The fractional clock divider circuit may provide compatible display clock frequencies for each of the two or more image streams. When a multi-image stream comprises the two image streams, the asymmetric image splitter engine adjusts a vertical asymmetry of a first image stream with a shortest height to same height as a second image stream by adding vertical padding to the first image stream. The super-frame image streams may comprise image streams from video, LIDAR, radar, or other sensors.
Programmable fractional ripple divider
Embodiments included herein are directed towards a fractional feedback divider circuit and associated method. The circuit may include a programmable feedback divider including a plurality of flip-flops arranged in series. The programmable feedback divider may be configured to receive an input clock signal and a reset signal comprising at least one pulse and to generate a divided clock. The circuit may include reset logic configured to receive an input from the programmable feedback divider and to generate a reset signal. The circuit may include a first D flip-flop configured to receive the reset signal and to generate an output and a second D flip-flop configured to receive the output from the first D flip-flop and to generate a second output. The circuit may further include a multiplexer configured to receive the second output and to generate an output clock signal.
