Abstract
Methods for preprocessing pixel data using a Direct Memory Access (DMA) engine during a data transfer of the pixel data from a first memory (e.g., a DRAM) to a second memory (e.g., a local cache) are described. The pixel data may derive from an image capturing device (e.g., a color camera or a depth camera) in which individual pixel values are not a multiple of eight bits. In some embodiments, the DMA engine may perform a variety of image processing operations on the pixel data prior to the pixel data being written into the second memory. In one example, the DMA engine may be configured to identify and label one or more pixels as being within a particular range of pixel values and/or the DMA engine may be configured to label pixels as belonging to one or more pixel groups based on their pixel values.
