or more like combining steps without explicitly having to combine layers?

OK but is there any way to layer docker files? I'm not talking about compose, I mean like combining layers from different dockers in a nice way?

I'm working on revitalizing a FPGA DSP from my first failed startup. It's a RISC-V processor with a vector machine glued onto the side. It's capable of 30 second rapid testing of new algorithms which normally takes hours in FPGA land. Looking for a clear way to describe this novel approach to DSP.

Speaking only of CMake, it makes my life much much easier. If a project has < 5 files, a pure makefile is just fine. However once it gets any larger CMake makes linking, recompile times, and other stuff much much eaiser

This seems like a really stupid idea to me. Who is to say that gcc isn't a framework? How about the Linux kernel? How about x86 or an Intel CPU? Even a 555 timer chip is a framework

Assuming you mean a digital lowpass filter; this won't work. The ultrasonic input is saturating the microphone. In this situation, no amount of digital filters can recover the desired signal (the speech). If there was a physical low pass filter (not sure if these exist) that was placed over the microphone, that would work
