Project:  Real-time Verification Software for Hyperspectral Data Compression on System-on-Chip
Disciplines:  Electrical Engineering and Computer Science, Computer Science
Mentor:  Didier Keymeulen, (JPL),, Phone: (818) 354-4280
Background:  Efficient on-board lossless hyperspectral data compression reduces data volume in order to meet NASA limited downlink capabilities. The technique also improves signature extraction, object recognition and feature classification capabilities by providing exact reconstructed data on constrained downlink resources. At JPL a novel, adaptive and predictive technique for lossless compression of hyperspectral data was recently developed. This technique uses an adaptive filtering method and achieves a combination of low complexity and compression effectiveness that far exceeds state-of-the-art techniques currently in use. A hardware implementation of the compression algorithm was on a Field Programmable Gate Array (FPGA)
Description:  The project consists to develop a real-time data processing to verify the real-time data products of the FPGA data acquisition and compression for spectrometer using the new CHROMA detector with 1280 by 480 pixels at 120 frames per seconds image. The verification software will be written in in C and integrated in the ARM Cortex9 processors in the Zynq System-on-Chip device as a standalone verification tool running in parallel with the data acquisition
