Linear Memory Accessor and Updater Functions
First, a quick note about virtual, linear, and physical
addresses:
- Linear (or Virtual) Address: In the flat memory model (see
Intel Vol. 1, Section 3.3.1), memory appears to a program as a single,
continuous address space, called a linear (or virtual) address
space. An address for any byte in linear address space is called a
linear address. When paging is disabled, then a linear address is the
same as a physical address.
- Physical Address: The memory that the processor addresses
on its bus is called physical memory. Physical memory is organized as
a sequence of 8-bit bytes. Each byte is assigned a unique address,
called a physical address. When employing the processor's memory
management facilities, programs do not directly address physical
memory.
