The CCSDS 122.0-B-1 specification is part of a standards suite developed by the Consultative Committee for Space Data Systems. The CCSDS is formed by the major space agencies of the world for the development of communications and data systems standards for space applications. The CCSDS 122.0-B-1 fits the compression requirement for a wide range of spaceborne two-dimensional spatial image data. In these applications the requirement is for a scalable data reduction, with the option to use lossless or lossy compression, using a memory-efficient and reduced complexity algorithm that results in a fast, low-power and compact hardware implementation.
The new Alma Technologies CCSDS-122-E encoder IP core is an advanced implementation of the CCSDS 122.0-B-1 image data compression standard and supports image or video data with a pixel dynamic range of up to 16 bits. The CCSDS-122-E is a complete and autonomous CPU/GPU-less encoder. It accepts the uncompressed image data in standard raster scan pixel order and outputs standalone and fully compliant CCSDS 122.0-B-1 byte-stream format. The CCSDS-122-E is designed for enabling high-rate data compression, with low resource usage, in both FPGA and ASIC implementations.
Similar to JPEG 2000, the CCSDS 122.0-B-1 utilizes a two-dimensional Discrete Wavelet Transform (DWT) for image data decorrelation. CCSDS 122.0-B-1 uses a 9/7 integer DWT for the lossless compression, while a 9/7 float DWT is also specified for improved lossy compression efficiency, especially at low bit-rates. Both DWT options are available by the Alma Technologies CCSDS-122-E encoder. For complete control by the application of the lossy compression ratio, the CCSDS-122-E includes also the optional rate control functionality that is provisioned by the standard.
The CCSDS 122.0-B-1 standard was developed to balance between compression performance and complexity with particular emphasis on spacecraft applications. Compared to JPEG 2000, it achieves slightly lower, but essentially similar, lossless and lossy compression efficiency. Due to its reduced complexity, it requires significantly less silicon logic area, along with reduced amount of internal memories, and achieves higher throughput. The Alma Technologies CCSDS-122-E encoder realizes all these expected benefits, while also not needing an external memory device for its implementation.
