2024年2月7日 · Fun fact: the equivalent instruction on a real ISA, like x86's hlt, stops the clock until the next external interrupt. So it's basically a wait-for-interrupt instruction. Or something you can put in a loop to save power if you don't have any work to do at the moment. –

2015年4月17日 · I'm attempting to write a short LC-3 program that initializes R1=5, R2=16 and computes the sum of R1 and R2 and put the result in memory x4000. The program is supposed to start at x3000. Unfortuna...

2021年3月21日 · I haven't ever used LC-3 assembly, but maybe this instruction list could help you. Sometimes when I'm making a potentially long procedure that may need to use things like loops, I like to write it in a higher level language and then slowly make the function more "assembly-like" (expand large operations like a+b*c/whatever, replacing for/while loops with do while loops, even goto if I'm having ...

2016年4月17日 · Thank you so much for your answer. I will definitely be trying this soon. I'm confused as to when you say LC3 is a language specifically designed for educative purposes. It is actually a machine and I'm able to program for it in both assembly and machine language. Am I missing something? Thank you –

2009年12月25日 · Assembly instructions (LD, ST, ADD, etc. in the case of the LC-3 simulator) correspond to binary instructions that are loaded and executed as a program.

2018年12月13日 · (And LC3 doesn't have store-immediate or store with an absolute address embedded in the instruction, because it's a fixed-width ISA. And it doesn't have stuff like memory-destination ADD; I think the only instruction that writes memory is str) –
