摘要： An apparatus to implement Huffman decoding in an INFLATE process in a compression engine. An embodiment of the apparatus includes a bit buffer, a set of comparators, and a lookup table. The bit buffer stores a portion of a compressed data stream. The set of comparators compares the portion of the compressed data stream with a plurality of predetermined values. The lookup table stores a plurality of LZ77 code segments and out puts one of the LZ77 code segments corresponding to an index at least partially derived from a comparison result from the set of comparators.

摘要： A graphic display apparatus in which the data to be displayed is stored as two types of data word, one type representing groups of increments of beam displacement of a beam displacement tube and the other representing differences between the data constituting a raster line and that of next succeeding line. The data for each line formed from the first type of words is temporarily stored in a line store while being displayed on the tube. The contents of the line store are modified according to any second type words received during the display period so as to convert the stored data into that for the next line to be displayed.

摘要： An apparatus to implement a deflate process in a compression engine. An embodiment of the apparatus includes a hash table, a dictionary, comparison logic, and encoding logic. The hash table is configured to hash a plurality of characters of an input data stream to provide a hash address. The dictionary is configured to provide a plurality of distance values in parallel based on the hash address. The distance values are stored in the dictionary. The comparison logic is configured to identify a corresponding length for each matching distance value from the plurality of distance values. The encoding logic is configured to encode the longest length and the matching distance value as a portion of a LZ77 code stream.
