Project goals
- Demonstrate a parallel operation of CCSDS-121 and CCSDS-123 compatible multispectral image compression IP cores on a high-performance FPGA evaluation board
- Combine the CCSDS-123 and CCSDS-121 IP cores, demonstrate parallel operation of image compression algorithms, thus serving as a baseline for future developments in this technological area
- Show the SpaceFibre interface as a high-throughput data transfer interface used to transmit hyperspectral images to the CCSDS-121 and CCSDS-123 compression cores to perform on-the-fly image compression
- Receive hyperspectral images to be compressed through SpaceFibre interface (2.5 Gbps)
- Images in Band Interleaved by Pixel format (BIP)
- Send back compressed image through SpaceFibre interface
- Use different SpaceFibre virtual channels for both compression cores (VC1 and VC2)
- Allow configuration of compression IP cores through SpaceWire RMAP (100 Mbps) or SpaceFibre VC0 interface
Compression Modes
Online mode (on-the-fly):
- Image data received through the SpFi interface is transmitted directly to one of the compression cores
- Data compression in the selected compression core
- Compressed data is returned on the same SpFi virtual channel
- Simultaneous online compression using both compression cores is allowed
Offline mode:
- Image data received through the SpFi or SpWi interface is stored in the external DDR memory
- A DMA controller reads from the memory and writes to one of the compression cores
- Compressed data is stored back in the external memory
- The compressed data is read from the external memory with SpW or SpFi VC0 (RMAP)
