Low-memory and high-performance architectures for the CCSDS 122.0-B-1 compression standard

Two low-memory and high-performance architectures for the CCSDS 122.0-B-1 standard are proposed. They use novel memory organizations to reduce the total memory requirements in order to be implemented in a single FPGA device. The architectures were implemented in radiation-hardened and commercial FPGA devices. Based on the experimental results for the case of Virtex5QV radiation-hardened device, the throughput is 135 MSamples/sec for image with 12 bits/pixel and horizontal resolution up 8192 pixels. Also, the proposed architectures outperform the existing one in terms of the memory requirements and area.
