LC3 Instructions - LD, LDR, LDI, LEA

[@dailyhypothesies3477]

I didn´t understand the LDR because i needed an example. What do you mean by base and offset. How is it used in practice? You´re explaining it well, but in a language i don´t yet understand. Simplify please

why using LDI instead of LD? it takes more cycles. Am i missing something? Thanks

[@juanpablomercksifontes7026]

thanks for the videos!! the videos are helping me a lot

[@juanpablomercksifontes7026]

i have a question, i don't understand very good the opcode LDI, the part of the diagram where are the steps. My question is: why happen this? MDR

[@jebdiankerman5029]

That's what LDI is supposed to do, which is fetching the content of another location in the memory, read that content as another address, and store the content of that newly found address. Think of it as a treasure map, you were told to go to a location, you get there, you find a new hint that tells you where the treasure actually is, and you go to where the hint tells you to, and finally found the treasure.

The video sound is pretty good, beyond my imagination

[@LIANGE1011]

wait is there not a OR operation in lc-3?

[@hass1697]

LC-3 use Not instead of shifting !!

[@charitoncharitonidis906]

hahaha it's pretty late but you can use DeMorgan's theorem which says: A OR B = A' AND B'

[@kregg34]

its A OR B = NOT( NOT(A) AND NOT(B) ) actually
