A Parallel FPGA Implementation of the CCSDS-123 Compression Algorithm
Orlandic, Milica; Fjeldtvedt, Johan Austlid; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)Satellite onboard processing for hyperspectral imaging applications is characterized by large data sets, limited processing resources and limited bandwidth of communication links. The CCSDS-123 algorithm is a specialized ... -
An Efficient Real-Time FPGA Implementation of the CCSDS-123 Compression Standard for Hyperspectral Images
Fjeldtvedt, Johan Austlid; Orlandic, Milica; Johansen, Tor Arne (Journal article; Peer reviewed, 2018)Hyperspectral imaging (HSI) can extract information from scenes on the earth surface acquired by airborne or spaceborne sensors. On-board processing of HSI is characterized by large datasets on one side and limited processing ... -
CubeDMA-Optimizing Three-Dimensional DMA transfers for Hyperspectral Imaging Applications
Fjeldtvedt, Johan Austlid; Orlandic, Milica (Journal article; Peer reviewed, 2018)Onboard computing is one of the principal needs in space-related technology in the recent years. In particular, onboard hyperspectral imaging (HSI) processing has advanced significantly. Due to advances in sensor technology, ... -
Efficient Streaming and Compression of Hyperspectral Images
Fjeldtvedt, Johan Austlid (Master thesis, 2018)As a part of the SmallSat project at NTNU, a satellite payload capable of capturing and processing of hyperspectral images is being developed. Several processing steps are performed on-board in the satellite, as well as ...
