Reconfigurable Architecture For WTLS

The rapidly growth of the transmitted data amount, over wireless networks, has triggered special needs for compression, in an attempt for real-time communications. wireless transport layer security (WTLS) is the security layer for both wireless application protocol and open mobile alliance. In spite of the fact that a great, a compression unit is optional. Compression in wireless portable devices is a sensitive issue due to the restricted resources environment. The composite compression encoders allocate area that system can not support. In this paper, an area optimized multi coder-processor is proposed for the WTLS. The proposed system consists of three units and serves three different types of compression: speech (ADPCM), test (Huffman) and image (RLE). The proposed processor minimizes the area resources compared with other published works and has competitive performance. The paper deals with reconfiguration of any of the compression technique at any point of time
