Paper Abstract

The Consultative Committee for Space Data Systems (CCSDS) 121.0-B-2 lossless data compression standard defines a lossless adaptive source coding algorithm which is applicable to a wide range of imaging and nonimaging data. We introduce a field-programmable gate array (FPGA) implementation of CCSDS 121.0-B-2 as an intellectual property (IP) core with the following features: (a) it is enhanced with a two-dimensional (2-D) second-order predictor making it more suitable for image compression, (b) it is enhanced with near-lossless compression functionality, (c) its parallel, pipelined architecture provides high data-rate performance with a maximum achievable throughput of 205  Msamples/s (3.2 Gbps at 16 bit) when targeting the Xilinx Virtex-5QV FPGA, and (d) it requires very low FPGA resources. When mission requirements impose lossless image compression, the CCSDS 121.0-B-2 IP core provides a very low implementation cost solution. According to European Space Agency PROBA-3 Bridging Phase, the CCSDS 121.0-B-2 IP core will be implemented in a Microsemi RTAX2000 FPGA, hosted in the data processing unit of the Coronagraph Control Box, of the Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun Coronagraph System Payload. To the best of our knowledge, it is the fastest FPGA implementation of CCSDS 121.0-B-2 to date, also including a 2-D second-order predictor making it more suitable for image compression.
