RISC-V.NET
RISC-V Emualtor running in the Browser, Native or .NET CLR
Introduction
RISC-V is an open standard Instruction Set Architecture (ISA) enabling a new era of processor innovation through open collaboration 
F# is an open-source language that makes it easy to write succinct, robust, and performant code. Through F#, you can run a RISC-V Emulator on .NET CLR, or make it run in the native environment through .NET Native AOT.
To run in the browser, there are two solutions:
Performance Warning
As you can see, this is not a mature solution, and it is almost impossible to become a mature solution. The performance of the simulator built through the above solution will inevitably have serious problems. The value of this project lies in my personal research and study, or to bring inspiration to others :)
Structure

├── RiscV.NET.Core
├── RiscV.NET.Core.Native.Test
├── RiscV.NET.Native
- RiscV.NET.Core: The core of RiscV.NET, using .NET Core standard class library and Fable compatible class library to ensure platform independence.
- RiscV.NET.Core.Native.Test: Native RiscV.NET.Core tests, not related to RiscV.NET.Native.
- RiscV.NET.Native: The native RiscV.NET.Core interface can be compiled into a local executable file through .NET Native AOT to run, or simply run on .NET CLR.
