abstract:Real mode, also called real address mode, is an operating mode of all x86-compatible CPUs. Real mode is characterized by a 20-bit segmented memory address space (giving exactly 1 MiB of addressable memory) and unlimited direct software access to all memory, I/O addresses and peripheral hardware.
Furthermore, the errorsof the forceduncouplingmethodand the measures of improvingitsprecisionby usingpseudo-forceiterationmethodbased onrealmodesare discussed.
