It is a 16-bit microprocessor , which is executed in as little as 400ns. In 1978, Intel released the 8086 microprocessor . This paper provide the information about the architecture , pin diagram , addressing modes , Interrupts and instruction set of 8086 microprocessor.Jyoti Chandel...
The Intel 8086 microprocessor, introduced in 1979, has 29 000 transistors packed on the 225 mm2 chip. The main feature of the microprocessor is the arithmetic and logic unit (ALU). The ALU allows the arithmetical manipulation of data, addition and subtraction with 8-bit systems and ...
A microprocessor chipset can have a CPU, memory, internal address and data bus circuits, registers, interfaces for peripherals, BIOS (basic input/output system), instruction set and timer clock, etc. Microprocessors are characterized by the technical parameters: bandwidth, which is the number of ...
Because the microprocessor has no way to access the configuration space directly, the computer vendor has to provide a way to do it. To access configuration space, the CPU must write and read registers in the PCI controller, but the exact implementation is vendor dependent and not relevant to...
In embedded systems, the microprocessor’s role and function are usually the same as those of the CPU in a general-purpose computer: control computer operation, execute instructions, and process data. In many cases, the microprocessor in an embedded system is also called the CPU. Memory is use...

Size− The microprocessor is of small size chip, hence is portable. Low Power Consumption− Microprocessors are manufactured by using metaloxide semiconductor technology, which has low power consumption. Versatility− The microprocessors are versatile as we can use the same chip in a number of ...
The first microprocessor 4004 was invented by Intel Corporation. 8085 and 8086 microprocessors were also invented by Intel. In 1981, Intel introduced an 8-bit microcontroller called the 8051. It was referred as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two...
The x86 architecture has a long and convoluted history dating back to 1978, when Intel announced the 16-bit 8086microprocessor. IBM selected the 8086 and its cousin, the 8088, for IBM’s first personal computers. In 1985, Intel introduced the 32-bit 80386 microprocessor, which was backward co...
They had very limited processing capability (equivalent to an Intel 8086), and memory capacity (128 K–1 MB), small displays, and very strict energy requirements. The Apple Newton and AT&T EO were examples of these types of devices [22]. Due to their limited functionality, the first-...
