Abstract: Machine-enabled methods of, and devices for, encoding color bitmap data as indexed red-green-blue (RGB) data for display.

Abstract: Embodiments of the present invention comprise systems, methods and devices for imaging device job management.

Abstract: Data is partitioned and processed along a bit plane that includes symbols holding a particular place in the ordered symbol sequences of digital information to achieve efficient compression and reduce processing complexity.

Abstract: A system and method are provided for estimating the weight of a document. The method comprises: determining the paper basis; determining the paper size; determining a document page count; and, in response to the determinations, calculating the weight of the printed document. In some aspects the method further comprises: determining the weight of the ink; and, determining the weight of the fuser oil, so that the calculated weight of the printed document includes the determined ink weight and fuser oil weight. In other aspects the method further comprises: selecting a transportation carrier; and, determining the transportation charges associated with the printed document using the calculated document weight. Some aspects further comprise: in response to selecting a carrier, selecting a document package. Then, calculating the weight of the printed document includes adding the weight of the selected package to the document weight.

Abstract: In a system where two types of data are to be compressed using hierarchical vector quantization (HVQ), it would be typical for there to be two compression tables, one optimized for each type of data. A boundary between the two types may occur within a block to be compressed. In this case, a third table, optimized for a block having both types of data, is used.

Abstract: Using hierarchical vector quantization (HVQ) to accomplish rotation in addition to compression and decompression. During the compression step the image is divided into segments and each segment is reduced to a codeword. These codewords are transposed so that the segments will be in rotated order when printed. Then the codewords are decompressed to form segments in which the pixels are in rotated order.

Abstract: A compression process of dividing each word to be compressed into least and most significant bits, and applying a different compression ratio to each. If the compression processes are lossy, both parts of the output can also be losslessly compressed before being output. Hierarchical vector quantization can be issued for either lossy compressor.

Abstract: In a system having a PCI bus, an additional memory attached to the bus to allow a higher speed of data transfer for a number of copies from the computer to a number of devices. The additional memory has a number of DMA channels, each associated with an I/O device. One copy of the data required by an I/O device is transferred to the memory at normal computer FIFO speed. Thereafter, multiple copies of that data can be transferred to the I/O device from the memory at the higher data bus speed.

Abstract: Printing hints can be efficiently compressed in a system using hierarchical compression (HVQ) by first using HVQ to generate compressed codewords, and then adding the printing hint to the codewords to generate an intermediate form of codeword, before sending this intermediate form to a pattern matching lossless compressor for final compression. Even though the same printing hint may be applied to a number of codewords, the overall compression will be affected very little by the addition of the printing hints since the hints are identical over a large number of codewords in series.

Abstract: A system for changing the source and destination devices of data transfers under software control. Default data transfers are made from numbered source devices to the same-numbered destination devices, the data requests being routed through multiplexers which pair, for example, source 1 with destination 1, source 2 with destination 2, etc. The multiplexer control signals originate in a register which is originally loaded with default control bits. However, in real time, the bits within the control register can be re-loaded to provide outputs other than the default values. Then, the data from a source can be directed to any one of the destination devices.

Abstract: A circuit for enabling data transfer between one data bus connected to a number of devices, such as accelerator cards, and a second data bus, such as one found in a computer. The two data busses are connected by a number of FIFO buffers, and an arbitrator selects a source and destination for each packet. The circuit allows the computer to freeze the data in any or all buffers so that it can be inspected and changed if necessary, but only after the entire current packet for the selected buffer or buffers has been transferred.

Abstract: A method is described for determining readiness of devices in a digital data bus system to transfer data signals. The bus system includes a bus having a clock line for communicating a clock signal, address lines for communicating address signals, data lines for communicating data signals, and control lines for communicating control signals. The bus system also includes a plurality of devices. Each device is connected to the bus and has an address on the bus. At least one device is a source device capable of sending data signals and at least one device is a destination device capable of receiving data signals. A bus controller connects to the bus and controls the bus. The control lines include bus request lines that connect each device to the bus controller for communicating a bus request signal from a device to the bus controller. The bus request signal indicates that the device is ready to send or receive data signals.
