为了既能达到较高的数据速率又能减少硬件资源

本文提出了组内串行

组间并行的扫描方式

并仿真实现了改进后的软件系统.实验结果表明

该扫描方式可以有效的降低硬件资源.

Abstract

Recommended Standard CCSDS 122.0-B-1 provides a compression algorithm which has an advantage over providing a trade-off between the compression performance and the implement complexity. However

there exist restricting relations between the data rate and the storage resources while implemented on hardware. In order to reduce the hardware resources of the algorithms implementation under low rate loss cost

in this paper we propose a novel scanning mode

which combines the serial and parallel bit plane scanning

and implement a software system based on the scanning mode. This scanning mode can reduce the hardware resources efficiently.
