Claim Text:
1. A method for compressed data transmission in an electron beam lithography system comprising: receiving a gray-tone image suitable for printing at least a portion of a pattern onto a substrate by operation of an electron beam lithography system; aggregating sets of lines of each of a set of regions of the gray-tone image into trilines, each region of the gray-tone image corresponding with one of a set of segments of a digital pattern generator of the electron beam lithography system; sequentially encoding each of a set of trilines of each of the set of regions of the gray-tone image by operation of encoding circuitry according to an encoding process based on acquired gray-tone values of each of the set of trilines, the encoding circuitry having one or more encoders, the one or more encoders equipped with a codebook configured to store a plurality of triline fragments and a write location; and transmitting the encoded trilines of the set of regions of the gray-tone image to a set of decoders of the digital pattern generator, each of the set of decoders corresponding with one of the set of segments of the digital pattern generator, wherein the encoded trilines of a region are transmitted to a decoder of a segment corresponding with the region.
