This chapter discusses the 8086 family history and architecture. The history of the 80脳86 chip family explains a lot about the current and future Intel products. The basis of the 80脳86 family of microprocessors began in 1972 when the Intel Corporation began selling an 8-bit microprocessor, ...
On the 8086, the shift amount is given by the 8-bitclregister. The running time of the instruction is proportional to the number of bits shifted, and the processor does not optimize shifts that are larger than the register size, so if you ask to shift by 255 places, it will run a l...
The evolution path of the Intel 8086 Architecture to support multi-user or multi-application real time operating systems which require memory protection and memory management facilities is described. The approach is truly evolutionary based on a logical extension of the current system model incorporating...
Introduced in 1978, the 8086 was the Intel CPU chip that defined the base architecture of the x86 family. Although the 8086 was used in some PCs, its 8088 brother was the one chosen for the first IBM PC (see8088). Seex86. Technical Specs ...
When the engineers at Intel designed the original 8086 processor, they had a special purpose in mind for each register. As they designed the instruction set, they created many optimizations and special instructions based on the function they expected each register to perform. Using registers accordin...
As discussed in Chapter 1. virtually ail contemporary computer designs arc based on concepts developed by John von Neumann at the Institute for Advanced Studies. Princeton. Such a design is referred to as the von Neumann architecture and is based on three key concepts: ...

As the original implementation of 32-bit extensions of 8086 architecture, the 8086 Instruction set, Programming model, Binary encodings are still the common denominator for all 32-bit x86 processors. The set of processors compatible with 80386 is collectively termed as x86 or i386 architecture. But...
