Abstract: In an example, a method includes receiving image data of an input image having lines therein. The method also includes storing a first portion of the image data in a circular buffer in a first memory, wherein the first portion begins at a circular buffer start line in the input image and ends at a circular buffer end line in the input image. The method includes storing a second portion of the image data in a linear buffer in a second memory, where the second portion is non-overlapping with the first portion. The method includes processing the second portion of the image data to produce a first block of an output image. The method includes processing the first portion of the image data to produce a second block of the output image.

Abstract: An image signal processor includes a first matrix processing circuit, a post processing circuit, a second matrix processing circuit, and a split visual and analytics circuit. The first matrix processing circuit is configured to receive a plurality of component images generated based on an image captured by an image sensor and generate a plurality of first matrix outputs based on the plurality of component images. The post processing circuit is configured to perform color conversion on the plurality of first matrix outputs to generate a first luminance component of the image and a chrominance component of the image. The second matrix processing circuit is configured to perform color conversion on the plurality of first matrix outputs to generate a second luminance component of the image and a saturation component of the image. The split visual and analytics circuit is configured to generate visual and analytic data of the image.
