Abstract: A code decompression engine reads compressed code from a memory containing a compressed code part and a dictionary part. The compressed code part contains a series of instructions being either an uncompressed instruction preceded by an uncompressed code bit, or a compressed instruction having a compressed code bit followed by a number of segments field followed by segments, followed by a directory index indication a directory location to read. Each segment consists of a mask type, a mask offset, and a mask.

Abstract: A code decompression engine reads compressed code from a memory containing a series of code parts and a dictionary part. The code parts each have a bit indicating compressed or uncompressed. When the code part is compressed, it has a value indicating the number of segments, followed by the segments, followed by an index into the dictionary part. The decompressed instruction is the dictionary value specified by the index, which is modified by the segments. Each segment describes the modification to the dictionary part specified by the index by a mask type, a mask offset, and a mask.
