This repository contains the Ray Marching accelerator to be used in 2D Particle Filters. Tested on Kria KR260.
In the hls/ folder you can find the file sources for the accelerator and the rmds.tcl script to generate and export the RTL accelerator.
In the hw/kria folder you can find
rmds.tcl- the hardware block design for the RMDS system design on Kria.pl.dtsi- pre-cooked devicetree bindings for the PF and its reserved shared memory spacesshell.json- a pre-cooked shell file to be used in xmutilsdesign_1_wrapper.xsa- a ready-to-use bitstream archive
Run hls/build_rm.tcl to build the hardware accelerator, source the rmds.tcl design into Vivado and generate the corresponding bitstream. We also package our pre-generated xsa in the hw/kria folder.
Compile the hw/kria/pl.dtsi file into a device-tree blob overlay with dtc -I dts -O dtbo -i hw/kria/pl.dtsi.
Finally package the design_1_wrapper.bit.bin, shell.json and pl.dtbo files into a single folder named rmds and copy it into the KR260 in the /lib/firmware/xilinx/ folder.
Finally, use xmutil loadapp rmds to flash the hardware design in the programmable logic.
