Intel registers manual

As mentioned before, these registers are extended to 64 bits and eight new registers are added. bit mode also has few surprising features, described in General-Purpose Registers in Bit Mode in manual Basic Architecture (synopsis): In bit mode, there are 16 general purpose registers and the default operand size is 32 bits.

renamed AMD Intel named their implementation IAe and then EMT There are some slight incompatibilities between the two versions, but most code works fine on both versions; details can be found in the Intel® 64 and IA Architectures Software Developer's Manuals and the AMD64 Architecture Tech Docs. We call this intersection flavor x Document. Description. Intel® 64 and IA architectures software developer’s manual combined volumes: 1, 2A, 2B, 2C, 2D, 3A, 3B, 3C, 3D, and 4. This document contains the following: Volume 1: Describes the architecture and programming environment of processors supporting IA and Intel® 64 architectures. Real mode registers are 16 bits, and they include: Four generic purpose registers: AX, BX, CX, DX. The upper 8 bit part of them can be accessed as AH, BH, CH, DH and the lower part as AL, BL, CL, DL. A register to hold the offset of the currently executing code: IP. Four registers to be used as pointers: SI, DI, BP, SP.
