SUNRISE项目被设想为一个太阳天文台，用来研究太阳低层大气中的物理过程。为了实现这一目标，SUNRISE III任务结合了两个新仪器，TuMag和SCIP，作为其科学有效载荷的一部分。这些仪器在大约7天的时间里产生了大量的数据，这些数据是由400万像素的传感器产生的，速度高达32帧/秒。传感器捕获的大量数据必须储存起来，以便以后在地面上进行分析。为了以有效的方式完成这种数据存储，CCSDS 121.0-B-2压缩标准的定制版本，称为SLoC，已经为SCIP和TuMag仪器开发，在本工作中提出。实验结果证明了所提出的压缩解决方案对于SUNRISE III任务的适用性，在Xilinx Kintex UltraScale XCKU040 FPGA上运行在150 MHz的目标时钟频率上，分别仅使用0.8%和3.1%的可用bram和lut。
The SUNRISE project has been conceived as a solar observatory to investigate the physics processes in the lower atmosphere of our Sun. With this aim, the SUNRISE III mission incorporates two new instruments, TuMag and SCIP, as part of its scientific payload. These instruments generate a considerable amount of data produced by 4 Mpixel sensors running up to 32 fps during around seven days. The considerable amount of data captured by the sensors must be stored for a later analysis on ground. In order to accomplish this data storage in an efficient way, a tailored version of the CCSDS 121.0-B-2 compression standard, named SLoC, has been developed for the SCIP and TuMag instruments, which is presented in this work. Experimental results prove the suitability of the proposed compression solution for the SUNRISE III mission, running over the targeted clock frequency of 150 MHz and using only the 0.8% and the 3.1% of the available BRAMs and LUTs, respectively, on a Xilinx Kintex UltraScale XCKU040 FPGA.
