A WebAssembly processor in Chisel.

WASM PROCESSOR

This is a processor design for WebAssembly ISA (work in progress).

It is my hobby project and can serve as an exploration of secure ISA design for microprocessors.

Project progress:

• Overall datapath for instruction & data fetching and execution
• i32 arithmetic & logic instructions
• block and loop structures and conditional branching
• Function calls
• Handle I/O and other side effects in a WebAssembly style (imported function as system call)
• An extra pipeline behind standard WebAssembly toolchain to convert .wasm binaries into runtime ROMs (function tables, instruction ROM, etc.)
