The name of the project is “RUN LENGTH ENCOADING”. In this project transmit the data use different compression Techniques. In these Techniques input date is to be encoded. By use the techniques the input data is to be compress .In this project it is possible to reduce the input data. To compress the original input data or to reduce the input data it will never effect the original information and it is possible to consume less power for data transmission. It is possible to transmit the data efficiently by using these methods here two compression methods are there. 1) Lossless compression and 2) Lossy compression method. In this project to compress the input data by using lossless compression technique. To this project by using Xilinx 9.1i simulator and to write the code by using VHDL module.-The name of the project is “RUN LENGTH ENCOADING”.
