Abstract: The continuous growth of mobile, desktop and wired and wireless digital communication technologies has made the extensive use of the text data unavoidable. The basic characteristics of text data like transmission rate, bandwidth, redundancy, bulk capacity and co-relation among text data makes basic compression algorithms mandatory. The research exploration in the field of text data compression is huge. In this research paper we investigate the performance evolution of basic compression algorithms on text data. We are adopting RLE (Lossless) compression and its modified version of algorithm, named K-RLE (Lossy). The basic and proposed system architecture, design, complexity, and performance could be analyzed and compare using MATLAB Language, which is the quick tool to estimate performance of the system. The KRLE compression algorithm is basically used to compress the repeated unwanted data. This has implemented using ARM7 low cost embedded processor. To implement this project on the processor the external devices like 16X2 LCD, RESET circuit, RS-232 cable have interfaced to this controller.
