An Operating System in Go
summary
TinyGo compiles Go for microcontrollers and can run without an OS by targeting bare metal hardware; a paper reports TinyGo binaries on a Raspberry Pi Pico are 3.5× smaller than Rust/C but about 1.5–2× slower, while another study on ESP32 finds TinyGo matches C’s speed and shows no jitter versus FreeRTOS. Working components include multicore goroutine support, a userspace networking stack (Alneto) on MCUs, and practical tooling like print allocs revealing three startup allocations for a blinky program.
