8086 works only with four 64kb segments within the whole 1mb memory. the internal architecture of intel 8086 is divided into 2 units: the bus interface unit (biu), and the execution unit (eu). these are explained as following below. 1. The 8086 (also called iapx 86) is a 16 bit microprocessor chip designed by intel between early 1976 and june 8, 1978, when it was released. the intel 8088, released july 1, 1979, is a slightly modified chip with an external 8 bit data bus (allowing the use of cheaper and fewer supporting ics), and is notable as the processor used in the original ibm pc design. 8086 cpu architecture the microprocessors functions as the cpu in the stored program model of the digital computer. its job is to generate all system timing signals and synchronize the transfer of data between memory, i o, and itself. it accomplishes this task via the three bus system architecture previously discussed. 8086 microprocessor is an enhanced version of 8085microprocessor that was designed by intel in 1976. it is a 16 bit microprocessor having 20 address lines and16 data lines that provides up to 1mb storage. it consists of powerful instruction set, which provides operations like multiplication and division easily. 8086 is a 16 bit processor which means that its alu and internal registers work with 16 bit binary word. data bus of 8086 microprocessor has 16 lines. so, it can read or write 16 or 8 bit data at a time to a memory port. address bus of 8086 is 20 bit which means it can address to 2 20 = 1 mb unique memory locations.

All general registers of the 8086 microprocessor can be used for arithmetic and logic operations. the general registers are: accumulator register consists of 2 8 bit registers al and ah, which can be combined together and used as a 16 bit register ax. al in this case contains the low order byte of the word, and ah contains the high order byte. 9. 8086 supports 2 modes of operation a. minimum mode b. maximum mode architecture of 8086 microprocessor: as shown in the below figure, the 8086 cpu is divided into two independent functional parts o bus interface unit(biu) o execution unit(eu) dividing the work between these two units speeds up processing. The intel 8086 is a 16 bit microprocessor intended to be used as the cpu in a microcomputer. the term “16 bit” means that its arithmetic logic unit, internal registers, and most of its instructions are designed to work 16 bit binary words. it has 16 bit data bus and 20 bit address bus. words will be stored in two consecutive memory locations. Birth of a standard: the intel 8086 microprocessor turns 40 today forty years ago, intel released the 8086 processor, introducing the x86 architecture that underlies every pc—windows, mac, or. X86 is a family of instruction set architectures initially developed by intel based on the intel 8086 microprocessor and its 8088 variant. the 8086 was introduced in 1978 as a fully 16 bit extension of intel's 8 bit 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16 bit address. the term "x86" came into being because the.

But in the case of 8086, if you see the block diagram of the architecture, you will find that the whole architecture is divided into two major parts: (1) bus interface unit (biu) and (2) execution unit (eu). 8086 microprocessor 8088 microprocessor; 1: the data bus is of 16 bits. the data bus is of 8 bits. 2: it has 3 available clock speeds (5 mhz, 8 mhz (8086 2) and 10 mhz (8086 1)). it has 3 available clock speeds (5 mhz, 8 mhz) 3: the memory capacity is 512 kb. the memory capacity is implemented as a single 1 mx 8 memory banks. 4. Intel 8086 intel 8086 microprocessor is the enhanced version of intel 8085 microprocessor. it was designed by intel in 1976. the 8086 microprocessor is a16 bit, n channel, hmos microprocessor. Definition: 8086 is a 16 bit microprocessor and was designed in 1978 by intel. unlike, 8085, an 8086 microprocessor has 20 bit address bus. thus, is able to access 2 20 i.e., 1 mb address in the memory. as we know that a microprocessor performs arithmetic and logic operations.
