1 4 Evolution Du Microprocesseur
Summary
TLDRThis video, part of a series on computer architecture, delves into the microprocessor's architecture and function. It begins with the history of computing devices, highlighting the ENIAC and the shift from vacuum tubes to transistors in 1955. The introduction of the microprocessor in the 1970s revolutionized computer production by reducing cost and increasing speed. The integrated circuit, invented by Jack Kilby in 1958, laid the foundation for the microprocessor. The Intel 4004, released in 1971, contained 2300 transistors and could perform 92,600 operations per second. Today's microprocessors, like Intel's i9 11900k with 17 billion transistors, demonstrate the exponential growth in transistor count, as predicted by Moore's Law. The video explains the binary language of microprocessors and how it's translated for human interaction, and it briefly touches on the transistor's role in forming logical gates that enable calculations. Stay tuned for the next part, which will explore how microprocessors execute instructions.
