Vlsi Design of Bit-Stream Compression Based On Run Length Encoding

Abstract

Reconfigurable system uses bit-stream compressionto reduce the bit-stream size and the memory requirement. Thecommunication bandwidth is improved reducing theirconfiguration time. Existing research has explored efficientcompression with slow decompression or fast decompression atthe cost of compression efficiency. This paper proposes a decodeaware compression technique to improve both compression anddecompression efficiencies. The three major contributions of thispaper are: i) Efficient bitmask selection technique that can createa large set of matching patterns; ii) Proposes a bitmask basedcompression using the bitmask and dictionary selection techniquethat can significantly reduce the memory requirement iii)Efficient combination of bitmask-based compression and runlength encoding of repetitive patterns.
