 ### Ever wanted to know what the absolute minimum requirements are to run linux?
 riscv_em is the answer. Yes, the emulator is capable of running Linux.
 
-One goal of this project is to be easily able to understand its source code and thus also the risc-v isa. You can also see this project as an attempt to directly translate the RISC-V ISA specs (Currently Unprivileged Spec v.20191213 and Privileged Spec v.20190608) into plain C.  
-Implementation focus is simplicity NOT efficiency! Altough I always try to improve it's performance whenever possible, as long as the code does not suffer losses in readability!

-Currently the emulator supports RV32IMA and RV64IMA instructions.  
-Furthermore it implements a CLINT (Core-Local Interrupt Controller) and also a PLIC (Platform Level Interrupt Controller), as well as a simple UART.

 ## UPDATE 2021: Now the emulator also fully implements PMP and MMU.
 Please see https://github.com/franzflasch/linux_for_riscv_em for a how-to-build appropriate linux images.
 
 * MMU support is currently only available for RV32 (Sv32). Support for RV64 MMU (Sv39, Sv48) will follow.
 * NOMMU is currently only supported for RV64 due to the kernel at the time of this writing only supports this for RV64.
