Abstract: Various examples are directed to a System on a Chip (SOC) and methods of operating the same. The SOC may access firmware code from a boot Read-Only Memory (ROM) of the SOC. The firmware code may comprise a plurality of functional blocks. The SOC may determine that firmware patching is active for the SOC and access patch data from a non-volatile memory of the SOC. The SOC may determine that a first functional block of the firmware code has been patched and access first patch code from the patch data. The first patch code may be associated with the first functional block. The SOC may execute the first patch code.

Abstract: System and techniques for an occupancy sensor are described herein. Images from a camera can be received. Here, the camera has a certain a field of view. A proximity indicator from a proximity detector can be received when an object enters the field of view. The images from the camera are processed to provide an occupancy indication. A first technique is used for the occupancy indication in the absence of the proximity indicator and a second technique is used otherwise.

Abstract: A line-detection system computes, using a local memory, a result of a partial conversion of image-space pixel data from image space to Hough space. The result is analyzed for edges corresponding to a line present in the partial conversion. The line is compared against other lines detected in previously computed partial results to identify a longest line in the image.

Abstract: A system for correcting distortion effects in a distorted image includes a memory controller for reading pixels (corresponding to a subset region in a destination image) of the distorted image from a system memory to local memory. A look-up table stores an offset and interpolation weight for each pixel, and an ALU computes, using stored values only in the local memory, values of each of the pixels in the region in the destination image.
