Intel 8086 architecture



Today we’ll take a look at Intel’s 8086, which is one of the oldest and yet
most prevalent processor architectures around.
We’ll make many comparisons between the MIPS and 8086 architectures,
focusing on registers, instruction operands, memory and addressing
modes, branches, function calls and instruction formats.
This will be a good chance to review the MIPS architecture as well.

The world of mobile computing has seldom been so exciting. Not, at least, for last 3 years when all that the chip giants could think of was scaling down the frequency and voltage of the desktop CPUs, and labeling them as mobile processors. Intel Centrino mobile technology is based on the understanding that mobile customers value the four vectors of mobility: performance, battery life, small form factor, and wireless connectivity. The technologies represented by the Intel Centrino brand will include an Intel Pentium-M processor, In ....etc

Intel 8086



Features of 8086 Microprocessor

1) 8086 has 16-bit ALU; this means 16-bit numbers are directly processed by 8086.
2) It has 16-bit data bus, so it can read data or write data to memory or I/O ports either 16 bits or 8 bits at a time.
3) It has 20 address lines, so it can address up to 220 i.e. 1048576 = 1Mbytes of memory (words i.e. 16 bit numbers are stored in consecutive memorylocations). Due to the 1Mbytes memory size multiprogramming is m ....etc

Intel?s Hyper-Threading Technology brings the concept of simultaneous multi-threading to the Intel Architecture. Hyper-Threading Technology makes a single physical processor appear as two logical processors; the physical execution resources are shared and the architecture state is duplicated for the two logical processors. From a software or architecture perspective, this means operating systems and user programs can schedule processes or threads to logical processors as they would on multiple physical processors. From a micro architecture pers ....etc

It?s quite natural that new technologies are emerging from time to time. The technology leader should not be backward in this process. Intel has been showing its leadership by developing new and new technologies like processors. This time Intel shows its power by the development of a new chipset series. Chipsets are not always cared by everyone. All focus on the Processors. But a processor without a good chipset to support its capabilities is not of full use. Here Intel makes a breakthrough by the development of new 9XX series chipsets. This se ....etc

REGISTER ORGANIZATION OF 8086
8086 has a powerful set of registers containing general purpose registers and special purpose registers. All registers of 8086 are 16 bit registers. The general purpose registers can be used as either 8 bit register or 16 bit registers. The general purpose registers are either used for holding data, variables and intermediate results temporarily or for the purposes like a counter or for storing offset address for some particular addressing modes etc. The special purpose registers, po ....etc
