Abstract
A controller for a persistent display device has an overall table of waveform data corresponding to different transitions of pixels from all pixel states to all others for differing operating parameters. A hardware LUT module receives input values containing new and current pixel state data and indexes to identify update requests, stores in LUT table memory space mapping values that are segments of waveform data generated in run time according to the operating parameters of each update request, and places segments of waveform data corresponding to the update requests into LUT output memory space. A SIMD module transposes waveform data of the update requests from the LUT output memory space, and places the transposed waveform data in respective frame scan buffers. An interface receives the transposed waveform data for the display device to update an image displayed on the panel.
