femto is a RISCV ISA-compatible light-weight soft-core MCU that can be implemented on an FPGA for DIY or educational purposes. femto is now released under MIT license.
femto是兼容RISCV指令集的轻量级MCU软核,可以在FPGA上实现,主要用于学习和DIY用途.femto目前在MIT许可证下发布.

This branch is a casual and trivial one (dev-only). If you're interested please vide other branches.
本分支是琐碎开发的分支,仅用于开发测试.如有兴趣请移步其它分支.

For now, basic branch is intended for a minimalist MCU that runs C programs. The advanced branch is intended for interrupt capabilities and faster bus architecture.
目前basic分支实现了最简的能运行C程序的MCU,而advanced分支则实现了中断功能和更快的总线结构.

On each branch SDK, bootloader and a demo app is implemented.
各个分支上均实现了SDK、bootloader以及demo应用程序.
