A camera system and method are disclosed. The camera includes a memory, a camera, and a processor. The memory stores an adaptively subsampled look-up table. The adaptively subsampled look-up includes varying levels of subsampling across the adaptively subsampled look-up table. The camera captures an image, and the captured image is distorted based on varying distortions within an optical system of the camera. The processor receives the captured image from the camera, corrects the distorted captured image based on the adaptively subsampled look-up table to create a correct image, provides the corrected image, and executes a safety feature based on the corrected image.

Embodiments provide line-based feature generation for vision-based driver assistance systems and methods. For one embodiment, a feature generator includes a circular buffer and a processor coupled to an image sensor. The circular buffer receives image data from the image sensor and stores N lines at a time of an image frame captured by the image sensor. The N lines of the image frame are less than all of the lines for the image frame. The processor receives the N lines from the circular buffer and stores one or more features generated from the N lines in a memory. Iterative blocks of N lines of image data are processed to complete processing of the full image frame, and multiple frames can be processed. The generated features are analyzed by a vision processor to identify, classify, and track objects for vision-based driver assistance and related vision-based assistance actions.

An apparatus for performing a method for loading a matrix into an accelerator includes an augmented direct memory access controller reading a matrix, in a data stream, from a first memory associated with a system processor and sending the matrix, in the data stream, to a second memory associated with the accelerator. The method further includes the augmented direct memory access controller extracting individual matrix elements from the data stream as the data stream is being sent to the second memory and analyzing the extracted individual matrix elements to determine if the matrix is any of a plurality of tested matrix class types as the data stream is being sent to the second memory.

An electronic device includes a first memory subsystem, a second memory subsystem and a direct memory access controller. In response to a first type of request from a processor, the direct memory access controller requests data from the first memory subsystem and provides the data to the second memory subsystem. In response to a second type of request from a processor, the direct memory access controller requests an uncompressed matrix from the first memory subsystem, compresses the uncompressed matrix to generate a compressed matrix, and provides the compressed matrix to the second memory subsystem. In response to a third type of request from a processor, the direct memory access controller requests a compressed matrix from the second memory subsystem, un-compresses the compressed matric to generate an uncompressed matrix, and provides the un-compressed matrix to the first memory subsystem.
