Abstract: A method of explicit lockstep for functional safety includes spawning, by a main thread, a first safe thread core and a second safe thread core. The method also includes initializing and mapping a first data register associated with the first safe thread core to each safe variable of a set of predetermined safe variables. The method further includes initializing and mapping a second data register associated with the second safe thread core to each safe variable of the set of predetermined safe variables. The method also includes comparing, by a hardware comparator, a first safe variable value in the first data register to a second safe variable value in the second register. The method further includes issuing an error completion to the first safe thread core and the second safe thread core when the hardware comparator detects a mismatch between the first data register and the second data register.

Abstract: A method for electronic imaging includes controlling an image sensor to capture a first sequence of first input images at a first frame rate having a first spatial resolution, and to capture a second sequence of second input images, interleaved with the first sequence and having a second spatial resolution lower than the first spatial resolution. The first and second sequences of the input images are processed to generate an third sequence of output images at a second frame rate higher than the first frame rate and having a third spatial resolution higher than the second spatial resolution.
