Stack Machine

Master zero-address computer architecture with the Stack-Machine CPU Simulator—an interactive visual environment built to demonstrate evaluation stack mechanics, Reverse Polish Notation (RPN), and low-level memory operations. Engineered for computer science students, compiler developers, and embedded system designers, this lightweight tool turns implicit CPU execution into a clear, visual learning experience.

Watch data flow through Push, Pop, ALU operations, and function call frames without the overhead of explicit register files. Step through bytecode step-by-step, inspect Top-of-Stack (TOS) and Next-on-Stack (NOS) states in real time, and gain immediate insight into how virtual machines like Java JVM, Forth, and WebAssembly process instructions. Whether you are building custom compilers, studying computer organization, or teaching microarchitecture, this software bridges abstract expression evaluation and physical execution.
