In my world, there was once an ox-made model of Tsinghua campus. What other amazing sights did you find?

How many transistors are there in a small CPU? Billions. How long does it take to build a CPU or even a complete computer? A Daniel answered this question with practical actions in the game "My World": it may take more than a year. This tutorial on assembling computers became a hit as soon as it was reprinted.

This is not a game strategy, but a course paper written by Fudan University. When he was a sophomore, he had a bold idea After a year of careful construction, he built a prototype computer named Alpha2 10 16. Although it can't be compared with the real computer, it can only realize some simple functions, but this computer is amazing in size, and you can already feel the huge amount of engineering just by looking at its complex structure. Some netizens lamented that it is a pity to send course papers, and it is almost possible to send academic papers. What can this computer do? The computer adopts Harvard structure instead of the more common von Neumann structure. The program memory and the data memory are placed separately. The program storage is 1kb, and the data storage is 0.5kb, which can realize various functional operations: addition, subtraction, multiplication and division, trigonometric function and matrix operation. It includes a 16-bit CPU and a 32-bit floating-point arithmetic unit (FPU).

The teenager made another grand plan: to make a 16 bit CPU. Next to the CPU, there is a single-precision 32-bit floating-point processor (FPU) with override function. Here, as an off-chip system, the calculator has not been abandoned. In the last quarter, the 16-bit calculator was changed into a calculator for full sequential logic circuit control and overflow judgment, which is unprecedented among Redstone circuit players. It borrows the ALU part of CPU for operation and transmits data through the bus.

Sophomore students began to develop computer Alpha2 10 16 as a project of the course "Network Virtual Environment and Computer Application". Judging from his interpretation of technical details, Ji was fully prepared in hardware and software at that time. Ordinary people may know the basics of logic circuits. Ordinary Redstone players can use the basic knowledge of logic circuits to build simple or complex Redstone circuits. Before Ji's project began, high-level Redstone players had also made calculators. But not many people dare to make a computer. Ji Hanwen not only thought of this, but also spent a whole year to realize it, almost finished.

After all, if you have an amazing brain, you must use it.
