Vector-graphics laser projector HD

http://people.ece.cornell.edu/land/courses/ece5760/FinalProjects/s2019/eam348_rbr76/eam348_rbr76/eam348_rbr76/index.html In this lab we used an FPGA to project vector image files using a laser and a set of motor-controlled mirrors known as galvanometers ("galvos"). Accomplishing this required us to move the galvos fast enough that the path traced out by the laser appeared to generate an image to a human observer. The FPGA with its immense signal processing and I/O capabilities was well suited for this high speed control task. Although controlling the galvos is a good task for an FPGA, reading a vector image file from memory and parsing it into a form that can be easily drawn is a complicated sequential problem which is better accomplished on a microcontroller. In addition to the FPGA, the system on chip board we used also included an ARM based microcontroller known as the HPS or Hard Processor System. We ran an embedded linux distro on this system, providing us with a clean operating system environment to run code from. Using this HPS we were able to include a C component which does all of the preprocessing work and then forwards the path on to the FPGA to draw.
