Abstract:
In a pixel shuffler for performing a matrix transposition of data representing each of a plurality of video lines for a Reflective Liquid Crystal Display (RLCD) panel, an address generator for video pixel reordering within each of said lines, said address generator comprising:a) an SRAM storing a sequence of pixel addresses for successive video lines for said RLCD panel and having at least one address input, a data input and at least one data output; b) a combinatorial converter for converting an address value of a current video line to a corresponding address value of a successive video line; c) a first buss connecting said converter output to said SRAM data input, whereby data from said SRAM is converted and written back to said SRAM; and d) a second buss connecting said at least one SRAM data output to a memory bank of said pixel shuffler, whereby said second buss delivers an address from said memory bank read-modify-write mode to operate upon a video pixel data stream permitting operation of said pixel shuffler with said memory bank requiring a limited capacity relative to conventional pixel shuffler memories.
