Abstract: A device such as a color printer includes a main memory, a cache memory, and a convolutional neural network configured to convert pixels from a first color space to a second color space. The convolutional neural network is organized into execution-separable layers, and loaded one or more layer at a time (depending on cache size) from the main memory to the cache memory, whereby the pixels are processed through each of the layers in the cache memory, and layers that have completed processing are evicted to make room for caching next layer(s) of the network.

Abstract: Devices, such as printers, for rendering compressed digital images, include a deserializer and multiple planar SRLE decoders each configured to transform an applied code from a serial input stream into one or more planar pixel values. The deserializer maintains a cursor position for each of the planar SRLE decoders and increments the cursor position of a corresponding one of the planar SRLE decoders in response to dequeuing a code of the corresponding planar SRLE decoder. The increment is an amount equal to a count of planar pixel values represented by the code. The planar pixel values output from the SRLE decoders are combined into a digital image rendering.

Abstract: An example printing method can involve a memory buffer of a printing system containing image data, and the method can include (i) issuing, by an initiator of the printing system, a single read-then-clear memory command; (ii) receiving, by a memory controller of the printing system, the single read-then-clear memory command; and (iii) in response to receiving the single read-then-clear memory command, the memory controller both (a) reading the image data from the memory buffer of the printing system and (b) after reading the image data, clearing the image data from the memory buffer of the printing system.

Abstract: Systems and methods for pseudo spot color printing on a printing device include receiving a print job specifying a spot color at a printing device not accommodating ink corresponding to the specified spot color, determining and storing a plurality of process color planes associated with corresponding process color inks accommodated by the printing device, and storing the plurality of process color planes in a memory of the printing device. A single spot color plane is determined and stored for the specified spot color. A plurality of other common planes is determined and stored. Upon reaching an end of the surface of the print job, the single spot color plane is converted to a plurality of spot color planes, which is merged with the plurality of spot color planes prior to printing a corresponding portion of the print job.

Abstract: A method and apparatus for generating pixelmap images for output to a raster device. The method and apparatus support scheduling and rendering bands, pages or planes from a job using multiple graphics processors and an array of buffers from an intermediate graphic order storage medium. The graphics orders are generated by a graphics order generator subsystem.
