Show HN: Program a robot to solve a maze on a CPU emulator
Lukas developed a CPU emulator using Python and Web Assembly, featuring arithmetic operations and an assembler for easier coding, inspired by the game "Turing Complete" and emphasizing logic gates' importance.
Read original article
Lukas discusses his exploration of Web Assembly (WASM) and the development of a CPU emulator using Python. The CPU features six general-purpose registers and a special register for input/output, supporting operations such as immediate values, arithmetic, copying, and comparisons. The design is based on simulated logic gates, with all operations derived from their fundamental properties. The CPU can perform basic arithmetic and logical operations, and it includes a mechanism for control flow through conditional evaluations. Lukas also highlights the challenges of programming in binary and the creation of an assembler to convert assembly code into binary, facilitating easier coding with features like labels for loops. He reflects on the learning experience gained from building the CPU and recommends the game "Turing Complete," which inspired his project. The project emphasizes the importance of understanding logic gates and their role in CPU design.
