The project I'm working on (a Libre CPU) could benefit from a symbolic coprocessor. I thought MIT/Scheme would be a candidate for a prototype, running directly on one of the CPU cores.
What would it take MIT/Scheme run on a bare metal CPU (RISC-V or PowerPC) from ROM? I'm guessing it would at least need some (hopefully) minimal Posix support. Has this been done before? CL has Mezzano, as a demonstration of this concept. The CPU will be running at 300 MHz, and there should be adequate memory--640K should be enough for a PC right? -- Stewart Milberger
