LC3 Assembly Bitwise Right Shift - Stack Overflow
2015年2月10日 · What I need to do it implement both a bitwise left shift, and a bitwise right shift using LC-3 Assembly. Basically, every bit has to be moved over one space in the direction of the shift, and a zero fills the empty space created. Examples: Right Shift: 01001001. 00100100→. Left Shift: 01001001. I've successfully implemented a left shift, by ...
LC3 Assembly Language: skipping over function call
2020年1月30日 · 1. I am writing a program in LC3 that reads in a file of integers, squares each element and adds their squares up. I need the 'squaring' part to be in a function but in my while loop the call to my function is completely skipped over. So what I am getting is just the numbers in the file summed up without squaring them first.

2016年4月17日 · You could do something like this: LEA R1, DIGITS ;R1 is our string pointer/counter. START. LD R2, R1 ;get the current character. ADD R1, R1, 1. NOT R2, R2 ;these lines. ADD R2, R2, 1 ;get the two's complement of R2, equivalent to -R2. ADD R3, R0, R2 ;this is like cmp r0, r2. BRnz ;loop back unless the characters are equal.
