QtRvSim articles, presentations and their recordings as well as more about Computer Architectures
courses at the Czech Technical University in Prague are presented at https://comparch.edu.cvut.cz/

The educational VHDL RISC-V core modeled according to the QtRvSim (single cycle and 5-stage
pipeline) has been designed by Damir Gruncl for the CTU FEE Advanced Computer Architectures course
(RVapo VHDL sources and tested in GHDL simulation, on Xilinx Zynq and iCE-40 FPGA targets. On Zynq
target it runs as PMSM motor control coprocessor to solve inverse and forward Clarke and Park
transformations and other low level control (top level project). See the complete list of the OTREES
CTU theses for more related topics.

The online training site for QtRvSim processed assembly and C tasks evaluation has been prepared by
