Meet the ALU: The mathematical brain powering every modern computer
In short: Discover how the Arithmetic and Logic Unit (ALU) performs every calculation your computer executes. This video demonstrates how to build an ALU from scratch using binary and logic gates.
The ALU serves as the fundamental component for all computations. By utilizing logic gates, we can construct this mathematical engine, which later forms the heart of the CPU.
The history of the ALU involves significant industry collaboration. While Fairchild prototyped the first ALU, the Fairchild 4711, in 1968, Texas Instruments introduced the 74181 in 1970. This 74181 design became a standard, with various companies like Fairchild producing compatible chips, such as the Fairchild 9341.
