Next picture shows SRAM memory layout for OMAP4460 SoC: In such situations, the loader will not copy the object codes or the content of it to the memory. @media(min-width:0px){#div-gpt-ad-ecomputertips_com-box-4-0-asloaded{max-width:300px!important;max-height:250px!important}}if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'ecomputertips_com-box-4','ezslot_4',643,'0','0'])};__ez_fad_position('div-gpt-ad-ecomputertips_com-box-4-0'); Typically, every operating system that supports loading programs will use loaders. The loader would add 1000 to each memory address in the program's instructions, so they refer to the correct memory locations. Loading a program involves either memory-mapping or copying the contents of the executable file containing the program instructions into memory, and then carrying out other required preparatory tasks to prepare the executable for running. The term "relocating" refers to the ability of the loader to adjust, or "relocate", the absolute addresses in a program so that it can be loaded at an address different from the one originally specified for it.
