The ADC, SBC, and RSC instructions utilise the value of the carry bit (C) whose value is stored in the Current Program Status Register (covered in the next lecture). Thus the ADC instruction example, ADC r0, r1, r2, adds the values stored in r1 and r2 and the value of the carry bit, placing the result in ... Web26 feb. 2024 · The basic unit of assembly language is the instruction. Each machine instruction is a small operation, like adding two numbers, loading some data from memory, jumping to another memory location (like the dreaded goto statement), or calling or returning from a function. (The x86 architecture has lots of not-so-small instructions as well. racunanje pdv unazad
