Abstract: An indirection texture magnification system and method for producing high-resolution indirection texture results. The system and method uses an indirection texture, designed for use with a low-resolution texture image, and a high-resolution texture image, which is a higher-resolution version of the low-resolution texture image. The indirection texture magnification system and method re-interprets an indirection texture computed for a low-resolution image so that a higher-resolution image can be used with the same indirection texture. This generates additional samples and allows the generation of a magnified, high-resolution indirection texture result. The indirection texture magnification system and method takes three or more neighboring pixel coordinates stored in an indirection texture and offsets those pixel coordinates in order to access the higher-resolution image with an increased precision.

Abstract: Waveform data contains waveform signals having transition events and is subdivided into data blocks. Indexing elements are provided for each waveform signal that correspond to a time range of the waveform data, and have a pointer to a data block within which transition events for the waveform signal are stored.

Abstract: A display uses column address circuitry having a plurality of multiplexing switching arrangements (50), each of which is associated with two buffers (46a;46b) for providing selected pixel drive signals. The two buffers provide respective pixel drive signals simultaneously to two adjacent columns, such that the pixel drive signal for one column starts before the end of the pixel drive signal for the column driven previously, and ends after the end of the pixel drive signal for the column driven previously. This enables a reduction in the number of buffers required and reduces the cross talk between column signals for adjacent columns within the group of columns shared by each multiplexing arrangement. This is achieved by ensuring that any capacitive coupling between first and second columns is charged to a static level before the signal on one of the columns is switched off.
