No-time Spending Data Moving Strategy Based on Parallel Mechanism in JPEG2000 Remote Sensing Image Real-time Compression System

To satisfy the real-time need of JPEG2000 satellite remote image compression system,a no-time spending data moving strategy based on parallel mechanism is proposed in this paper.It is implemented by splitting the EBC algorithm and adapting EDMA transport method,which parallels the operations of the algorithm and data moving.With the new data moving strategy,the coding efficiency can achieve one hundred percent and the total time for EBC algorithm implementation has been decreased by 46%.The new data moving strategy has been applied to satellite on-board JPEG2000 image real-time compression system successfully.
