چکیده
Digital image compression is a very popular topic in the field of multimedia processing. The major focus of work is to develop different compression schemes/algorithms to provide good visual quality fewer bit to represent an image in digital format. This paper work describes software and hardware implementation of Embedded Zerotree Wavelet (EZW) image Coder-Decoder (CODEC).The EZW image CODEC is used to compress and decompress gray scale image in image compression system. Here, EZW CODEC is implemented by Texas Instruments Digital Signal Processor (DSP) TMS320C6713 board. The EZW CODEC algorithms has been transferred into C and assembly code in Code Composer Studio (CCS) in order to program the C6713 DSP processor. The statistical analysis is also carried out with profile statistic available in CCS environment. With the development tools provided for the C6713 DSP platform, it created easy-to-use environment that optimizes the devices’ performance and minimizes technical barriers to software and hardware design
