Fast and compact

* Note, first "fast" then "compact", the focus is on speed and execution * efficiency and then on code size. This does not mean that the OS is large, - * the kernel size with all the subsystems activated is around 5.3KiB + * the kernel size with all the subsystems activated is around 5.2KiB * and can shrink down around to 1.2Kib in a minimal configuration * (STM32, Cortex-M3). It would be possible to make something even smaller but: * -# It would be pointless, it is already @a really small. * -# I would not trade efficiency or features in order to save few bytes. * . * About the "fast" part, the kernel is able to start/exit more than - * 200,000 threads per second on a 72MHz STM32. - * The Context Switch takes 2.3 microseconds on the same STM32. + * 220,000 threads per second on a 72MHz STM32. + * The Context Switch takes 1.41 microseconds on the same STM32. * *

Tests and metrics

* I think it is nice to know how an OS is tested and how it performs before -- cgit v1.2.3
