Offset in memory management

WebbGoals and Tools of memory management • Allocate memory resources among competing processes, – maximizing memory utilization and system throughput • Provide isolation between processes – Addressability and protection: orthogonal • Convenient abstraction for programming – and compilers, etc. • Tools – Base and limit registers ... Webb25 jan. 2014 · The variable a will be an offset in memory, let's say, pointing to address 0, b will point at address 33 and c at 34 (supposing no alignment optimization). So, allocating 1Kb of static data will not increase the size of your code, since it will just change an offset inside it. The actual space will be allocated at load time.
