Question

Briefly explain the architecture of the 80386 microprocessor.

Answer 1

The Intel 80386, also known as i386 or just 386, is a 32-bit microprocessor introduced in 1985.[1] The first versions had 275,000 transistors[2] and were the CPU of many workstations and high-end personal computers of the time. As the original implementation of the 32-bit extension of the 80286 architecture,[3] the 80386 instruction set, programming model, and binary encodings are still the common denominator for all 32-bit x86 processors, which is termed the i386-architecture, x86, or IA-32, depending on context.
