The “Consultative Committee for Space Data Systems” (CCSDS) has recommended an image data compression standard: CCSDS 122.0-B-1, to be used onboard space data systems. This research presents the algorithm implementation of the CCSDS image data compression standard (CCSDS-IDC) on “Digital Signal Processor” platform (DSP). The algorithm is applied to two-dimensional digital grey scale image data from imaging payload devices and uses two-dimensional “Discrete Wavelet Transform” (DWT) followed by progressive “Bit Plane Encoder” (BPE) to generate the compressed encoded bit stream. This research aims to give an efficient implementation of the standard in terms of cost, memory utilization, customization flexibility, power and throughput, on the DSK6713 floating point DSP platform. DSP and “Synchronous Dynamic RAM” (SDRAM) based implementation scheme is adopted. SDRAM dynamic memory allocation scheme is used for program, data and working memory. DSP multiple ALUs and pipelining has been utilized for efficient throughput. The results evaluated for the lossy compression scheme validate the performance of the algorithm onboard DSP platform. The implementation also serves as reference practical system to be used in space-borne applications.
