Webb31 mars 2024 · In computer engineering and low-level programming (such as assembly language), an offset usually denotes the number of address locations added to a base address in order to get to a specific absolute address. In this context an offset is sometimes called a relative address. What is the offset address? WebbA variable name implies the address of a variable and instructs the computer to reference the contents of memory at that address. Memory references have the following syntax:segment:offset(base, index, scale). Segment is any of the x86 architecture segment registers.

WebbThe base register is a general purpose register that contains a 32-bit address. The offset is a 16-bit signed integer contained in the instruction. The sum of the address in the base register with the (sign-extended) offset forms the memory address.

WebbFor example, if countLabel is stored at offset 0 of its segment, then the value 0 gets loaded into ESI. If we did not use the offset directive, then the actual value inside countLabel is loaded into ESI (i.e. 1000).
