Tyrone Marhguy builds a CPU from scratch

Tyrone Iras Marhguy, a Computer Engineering Student, University of Pennsylvania and a former Student, Achimota School, has built a working 8-bit Arithmetic Logic Unit (ALU) using only discrete MOSFETs.

The impressive 8-bit ALU is specifically an arithmetic and logic core which could eventually become part of a CPU.

In the viral video shared on X, Tyrone Iras Marhguy built the 8-bit ALU from scratch without a fully equipped laboratory in his dorm room.

In his post, Tyrone Marhguy on social media wrote, “I built a functional 8-bit ALU from 3,488 transistors in my dorm. 🎉

19 ops • 7 status flags • 5-bit control • 8-bit word size

– 3D site: https://alu.tmarhguy.com

– Repo: http://github.com/tmarhguy/alu

Verified with 1.245M test vectors (Verilog twin). This is the arithmetic engine on the path to a CPU — built from first principles.

Next up: optimization, error checks, PCB order, assembly, and hardware testing”. 

His post has since generated a buzz on social media with other netizen aswell posting saying, “Tyrone Marhguy, former Achimota Sch alumnus and a student of the University of Pennsylvania🇺🇸, has built a computer brain from scratch in his dormitory, crafting a working 8-bit ALU with 3,488 transistors🧠⭐

He is known for the case he won against Ghana in 2023”.

Another netizen added, “Tyrone Marhguy built a computer from scratch in 250 hours by using 3,488 transistors! This is the guy Achimota School nearly ended his dreams because of his hair. Top guy!”.

In related news, Tyrone Iras Marhguy was in the news last year when he commented on the brouhaha associated with SHS students keeping their hair.

According to Tyrone Iras Marhguy, he is not denying the challenges associated with SHS students keeping their hair, but obstacles shouldn’t excuse inaction.

Tyrone Iras Marhguy highlighted that some changes must come gradually.

His comments come following the growing debate on the strict directive on approved hairstyles for Senior High School students across the country.

In a long write-up on X, he wrote, “I understand the diverse views on whether we should keep our hair. I also get the fears: beauty competition among students and maintenance challenges, as my good friend Frederick Arkoh also pointed out. He told anecdotal scenes when @AchimotaSchool briefly allowed sneakers; it was a mess! Soon, classrooms filled with flashing red-green-blue shoes and rivalry until Motown rightfully demanded the familiar “Achimota” sandals.

However, these real challenges were summarized as “We are moulding character so that we won’t tolerate long hair.” Then came a straw man about beauty pageants and the slippery claim that keeping hair would somehow lead to no shoes, then no clothes, no school, no education, and finally, no Ghana”.

He added, “I’m not denying its challenges, but obstacles shouldn’t excuse inaction. None of us will have air in our lungs in 2325, but will future lads and lasses still shave their heads in the name of “moulding character”? Moulded into what, exactly? If shorter hair means better character, then no hair must mean perfection; it’s a conversation for another day.

Some changes must come gradually, but they begin with acknowledgement. After the first sem at the @Penn, I remember my silent frustration with my WASSCE Science (Elective ICT) curriculum. I thought I had a modern background, but it was QBasic 64, a useful yet relic beneath modern demands. Yet it remains, while Python is barely taught. Maybe it is a lack of infrastructure (I thought), but you don’t need GPUs and supercomputers to learn Python or C programming at school? That conversation may soon be visited, and if faulty, revised.

If we forbid discussion about our problems, we only preserve them”.
