CMake macros and utilities to include Vitis platform into the ROS 2 build system (ament) and its development flows.
NOTE: ament_vitis has a direct runtime Non-ROS dependency with Vitis unified software platform. Download and install Vitis here.
Synthesize C++ with Vitis HLS into an acceleration kernel
# example 1: resize_accel kernel
vitis_acceleration_kernel(
NAME resize_accel
FILE src/image_proc/xf_resize_accel.cpp
CONFIG cfg/kv260.cfg
INCLUDE
include/image_proc
${CMAKE_INSTALL_PREFIX}/include
TYPE hw
)
# example 2: rectify_accel kernel
vitis_acceleration_kernel(
NAME rectify_accel
FILE src/image_proc/xf_rectify_accel.cpp
CONFIG cfg/kv260.cfg
INCLUDE
include/image_proc
${CMAKE_INSTALL_PREFIX}/include

)Link and implement (place & route) a previously synthesized acceleration kernel with Vitis
# example 3: image_proc kernel
vitis_link_kernel(
