Microsoft Excel is well-known for its versatility (it may well even run first individual basic shooter Doom) – however who knew the spreadsheet software program is also used to construct a functioning CPU?
It would sound ridiculous, however that is exactly what a YouTuber named Inkbox has achieved, as demonstrated in an in depth 16-minute video. Inkbox achieved this feat with out utilizing any Visible Fundamental scripts or plugins, purely using Excel’s capabilities.
The result’s a 16-bit CPU that operates inside Excel at a clock price of 3Hz, full with 128KB of RAM, a 16-color 128×128 pixel show, and a customized meeting language. What’s extra, the CPU information can be found on Github for anybody to attempt.
Excel-ASM16 meeting language
One of the vital spectacular elements of this mission is Inkbox’s creation of a completely functioning meeting language for the Excel CPU. Named Excel-ASM16, it consists of 23 totally different directions and helps variables, labels, and even binary file help. These functionalities could also be primary for an meeting language, however they’re fairly vital given the constraints of a 16-bit CPU operating inside Excel.
Within the supply video, Inkbox offers a complete clarification of the features of Excel used within the mission and the way they have been manipulated to create a functioning 16-bit CPU. Regardless of the CPU’s velocity being not more than 3Hz, the time-lapse demonstration permits viewers to see the interior workings of the CPU.
Although the 16-bit CPU constructed inside Excel has its limitations, it demonstrates a powerful stage of technical ability and creativity on Inkbox’s half. The freely shared Excel-ASM16 and its CPU, with some pattern applications on Github, present a chance for any like-minded Excel customers to discover this distinctive creation for themselves.
