Disclosed is a computer processor () comprising a plurality of processing units (FU_n) and communication means () by which the plurality of processing units are interconnected. The communication means is dynamically configurable based on a computer program to be processed such that the processing units can selectively be arranged in at least first and second distinct configurations. The first distinct configuration (eg.) has a larger number of the processing units arranged in parallel than the second distinct configuration (eg.), and the second distinct configuration has a deeper pipeline depth than the first distinct configuration.

Reconfigurable VLIW processor

A method for performing an Inverse Discrete Wavelet Transform is disclosed. The method comprises inverse transforming, using filters () having specified filter widths, data from associated sub-bands in a first sub-band level, to form processed data in a corresponding sub-band in the second sub-band level. The method further inverse transforms, in a pipeline fashion, using second filters () having the same corresponding associated filter widths, the processed data in conjunction with corresponding data from associated sub-bands in the second sub-band level.

Inverse DWT method and apparatus

A method () and apparatus () is described for performing image rendering of high resolution computer generated images using limited memory and constrained rendering architectures. An image is segmented into a plurality of tiles (). A graphics renderer (), which is usually used for rendering low resolution images onto a display device (), is used to render one tile () at a time. The rendered tile images are combined to form a band of the image () and the image data of the band () is transferred to a printer engine () for printing. Each band () is rendered and transferred to the printer engine () until the whole image is printed.

Method and apparatus for printing computer generated images

A method of selecting transform segments from a data stream ( ), the stream comprising a plurality of blocks each comprising a plurality of transform segments, is disclosed. The selection reorders the transform segments in a block, and comprises, for each said block, steps of selecting a first set of transform segments ( ) suitable for direct inverse transformation to form a first data segment, selecting a second transform segment ( ) which is directly inverse transformable given availability of the first set ( ), identifying a third transform segment ( ) which is not directly inverse transformable given availability of the first set ( ) and the second transform segment ( ), and selecting a fourth transform segment ( ) which is required to support direct inverse transformation of the third transform segment ( ).
