uvm32: Minimalist Virtual Machine Sandbox for Resource-Constrained Microcontrollers
By
trj
Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
uvm32 is a minimalist, dependency-free virtual machine sandbox designed for microcontrollers and resource-constrained devices. It's implemented as a single C file with no dynamic memory allocations, using pure C99 with an asynchronous design. The system requires under 3KB flash and 1KB RAM on an STM32L0 (ARM Cortex-M0+). While based on a RISC-V emulator, uvm32 is intended for executing custom script-like logic rather than hardware simulation, and comes with tools to build efficient code for execution within the sandbox.
