Vortex tutorials at MICRO-55 (1st October 2022)
Description:
Vortex is an open-source hardware and software project to support GPGPU based on RISC-V ISA extensions. Currently, Vortex supports OpenCL/CUDA and it runs on FPGA. The Vortex platform is highly customizable and scalable with a complete open-source compiler, driver and runtime software stack to enable research in GPU architectures. As an application session, we will also have how to run drone applications on FPGA.
