What is a computer?

CPU's anatomy.

Liyu Chen



In this project, I plan to make the working theories of how computers work more accessible to audiences without prior background. I designed and implemented a 4-bit Arithmetic and Logic Unit from scratch using 74-series Integrated Circuits. The circuit is controlled by a microprocessor hosting a website on the Local Area Network. After logging into the website, the user would follow the “machine code-like” instruction prompted, input the designated values, select the mode of computation, then submit the form. The circuit would show the inputs in binary form, then calculate, show the output in binary form as well. By following the instruction and seeing the binary results being returned, the user can understand better how a computer functions from a more “down-to-earth” perspective.
