RASCAL ACIP
Progression
• Beginning:
• Algorithm development and
software verification
• IP System
• Custom Camera
• Hardware Acceleration
• Middle:
• Switched to Purchased Camera
• End:
• Frame Buffer Pipeline
• Single Run Hardware
Acceleration
• Lack of Linux Drivers
RASCAL ACIP
Results
• Completed software
verification and created test
Cubesat to test
angle/distance measurement
algorithms
• Obtained OV7670 test
camera and interfaced in
hardware
• Created basic video pipeline
(AXI IP cores) and verified
before adding in HLS and
Linux app
RASCAL ACIP
• Created Linux boot image
(with our PL)
• Work towards integration of
HLS blocks (hardware preprocessing)
• Work towards creation of
Linux drivers
• Work towards creation of
Linux application to carry
out OpenCV tasks
(classification and
angle/distance
measurments)
RASCAL ACIP
Roadblocks
• Vivado Tool Set
• Xilinx’s New Product
• Use of Xilinx IP
• Xilinx Documentation
• Incomplete
• Inconsistent
• Camera Interface
• Output Signals (needed VGA
timings)
• Configuration
• Co-design on Zynq processor
• Linux drivers
• Memory management
Xilinx XAPP1167
RASCAL ACIP
Future Work
• Flight camera/interface
• Higher resolution
• Attached to satellite
• Linux drivers
• Initialization of hardware
• Finalizing HLS
integration
• Hardware acceleration
portion
• Picked up by Bob when
he returns next semester
RASCAL ACIP
Conclusion
• Software verification and
testing
• Ensure mission can be
done, and the extent of
its usefulness
• Hardware
Implementation
• Significant progress
towards flight system
• Still work to be done
