How can I write the compare CMP command in a different form?

Question

assembler

Suppose I have given CMP R0, 1000, which is recorded in the memory cell at address 500, how can it be written differently? I'm just starting to understand assembler.

Answer 1

I don’t know what the assembler version is, but instead of cmp, you can do something like:

XOR R0, 1000    # если оба операнда совпадают - то результат будет равен 0
JZ LOC1         # прыжок если 0
