May 7, 2021 · The document summarizes the programming model of the X-86 32-bit family. It describes the three register groups: general purpose registers for storing data, segment registers for the code, stack, and four data segments, and a flag register group.

(1) The 8088 and 8086 defines basic programming model for X-86 family. (2) The 16-bit version for programming model is used in 16-bit microprocessor of X-86 family i.e., in 8088, 8086 and 80286.

Figure below illustrates the programming model of 8086 microprocessor. Some registers are general-purpose or multipurpose registers, while some have special purposes. The multipurpose registers include EAX, EBX, ECX, EDX, EBP, EDI, and ESI.

The 8088 and 8086 processors define the base programming model for the X86 family. Newer X86 processors, like the 386 and 486, offer greater computing power with faster speeds, 32-bit registers, and advanced addressing.

• All segments are mapped to the entire 32-bit physical address space at least two one for data and one for address space, at least two, one for data and one for code

Dec 7, 2023 · When using x86 assembly, it is important to consider the differences between architectures that are 16, 32, and 64 bits. This page will talk about some of the basic differences between architectures with different bit widths.

• For lab: PC and x86 • Illustrate several big ideas: – Stored program computer – Stack – Memory-mapped I/O – Software = hardware
