  • Platform supported: qemu-system-riscv64 simulator or dev boards based on Kendryte K210 SoC such as Maix Dock
  • OS
    • concurrency of multiple processes
    • preemptive scheduling(Round-Robin algorithm)
    • dynamic memory management in kernel
    • virtual memory
    • a simple file system with a block cache
    • an interactive shell in the userspace
