My web version of Mars MIPS, now have builtin C compiler

webMARS: A Browser-Based MIPS Simulator with a Built-in C Compiler

I have launched webMARS, a fully functional MIPS simulator that runs directly in your browser. This tool allows you to write, compile, and execute assembly code without any local installation. The latest update includes a built-in Mini-C compiler, enabling you to compile C programs directly into MIPS assembly within the same interface. The simulator provides a comprehensive view of registers, memory segments, and execution steps, making it an accessible platform for learning computer architecture.

Now have builtin C compiler

More from this day
