WebApr 24, 2024 · It is usual for CPUs to start executing from a fixed memory address, often near the "top" of the address space. Maybe our 12-address-bit CPU starts from 0xF00, for example. In that case it's useful to arrange the hardware around the CPU so that 0xF00 is mapped to a ROM. This is the concept of a "memory map". WebMemory-mapping is a mechanism that maps a portion of a file, or an entire file, on disk to a range of addresses within an application's address space. The application can then access files on disk in the same way it accesses dynamic memory. This makes file reads and writes faster in comparison with using functions such as fread and fwrite.
