Can anybody help me in understanding this assembly code of 8051?

Looks like it does 5 * 4 * 3 * 2 * 1 and then puts the result into R3

@irene @inaba can you explain meaning of each line...?

Sorry about that

@Ganofins

Put the number 5 into R0

Put the number 1 into B

Make the label JUMP and put R0 into A

Multiply A and B and put the result into A

Put the number from A into B

Then if R0 isn't 0, go to the JUMP lapel, and if it is then go on

Put A into R3

Close program

@irene shhhhhhh

@inaba @irene thank you so much guys

@Ganofins Any time my dude c:

By the way, how come you're doing 8051 asm?

Yeah, it computes the faculty of 5. Here a 1:1 port in C:

I’m gonna save this incase someone crying js is hard

@Fast-Nop Factorial 😀

@irene the syntax looks weird and hard for commoners like me

@asgs ah thanks, false friend translation. ^^

@devTea why, assembly is pretty straight forward with simple CPUs.

@irene Autocorrect 😂

@irene German. "Fakultät" means both (math) factorial and (edu) faculty at once.

@inaba tomorrow is my exam of microprocessor and Microcontroller subject

@devTea 😁

@irene actually, using the same word for both sounds a bit stupid in comparison to English or French.

Then again, I studded at a very renovated unity so that I'm not easily impregnated anyway. \o/

@Fast-Nop you might want to look up that word...

What I don't like about this is the use of jump as a label, as I'm used to jmp being used in x86 ASM

@irene also studded and renovated; I do believe that's sarcasm about more words that mean two things and are hard to translate.

@Ganofins good luck on the exam!

More riddles like this on dR would be cool

@svgPhoenix thanks

I’ve always admired people who can read machine code
