Thanks everyone for the discussion, and thanks @thierry for bringing up the topic of language/framework choice for the VTA core. I wish to share some of my thoughts on this topic.
As a FPGA engineer, I mostly wrote VHDL/verilog codes for my past projects. I must admit that I am not very familiar with chisel. But as far as I know, Chisel is still a Hardware Description Language (like VHDL/verilog) designed to describe digital circuits. On the other hand, Xilinx HLS/Accel/Intel HLS/OpenCL are high level synthesis frameworks which converting algorithms written in software codes into hardware design. The differences between HDL and SW languages are quite substantial. In my opinion, HDL languages are not programming languages, they are tools helping to describe low-level hardware circuits. We should always design the circuits first before we describing them in HDLs. Code re-usability is always an interesting topic in the HDL world. As HDLs are usually dealing with low-level hardware libraries, it is very much dependent on the low-level hardware components/IPs available on the hardware devices. In practice, it is always much more difficult to re-use HDL codes than SW codes, especially when performance/efficiency is a concern. Regarding to FPGA devices, that is mainly because different devices have different kind of resources / IPs / interconnect interfaces, even different CLB structures. On the other hand, high-level SW codes are focused to describe algorithms. It is mainly the compiler's job to map/translate it efficiently into the hardware circuits. In theory, as I see it, they are better candidates to minimize the number of design sources as low level hardware details are hidden into the toolkits themselves. However, the current state of HLS is not very mature, and a lot of design ideas could not be realized via HLS, and many #pragmas have to be introduced to aid the compiler optimizations. --- [Visit Topic](https://discuss.tvm.ai/t/rfc-vta-support-for-cloud-devices-opencl-compatible/6676/15) to respond.
