Tyrone Iras Marhguy, a Ghanaian student and young academic achiever, has accomplished the extraordinary: he built a working 8-bit ALU entirely from discrete MOSFETs, right from his dorm room.
With no prior chip design experience, Tyrone spent over 250 hours designing, simulating, and verifying an arithmetic logic unit composed of 3,488 MOSFETs, capable of performing 19 distinct operations and rigorously tested with more than 1.2 million vectors.
By diving deep into every logic gate and electron, he gained a firsthand understanding of the mechanics behind the “black box” we call a CPU. Phase 1 is complete, with optimisation, PCB assembly, soldering, and debugging next.
Tyrone’s work demonstrates that with MOSFETs, meticulous effort, and determination, computers could have existed long before cars. Beyond technical mastery, he is also recognised for his advocacy on religious freedom in education, proving that brilliance and principled leadership can go hand in hand.
