Microprocessor

Intel 8086 Architecture & Programming Features of 8086 Microprocessor 1) 8086 has 16-bit ALU; this means 16-bit number atomic number 18 directly neat by 8086. 2) It has 16-bit selective information bus, so it sens read info or write information to storage or I/O ports either 16 bits or 8 bits at a time. 3) It has 20 reference book point lines, so it evict extension up to 220 i.e. 1048576 = 1Mbytes of memory (words i.e. 16 bit come argon stored in resultant memorylocations). Due to the 1Mbytes memory size concurrent execution is make feasible as well(p) as several(prenominal) multiprogramming features watch been incorporated in 8086 design. Y.H.Dandawate 2 3/9/2006 Features Continued 4) 8086 includes a few(prenominal) features, which enhance multiprocessing capableness (it can be employ with math coprocessors same(p) 8087, I/O processor 8089 etc. 5) Operates on +5v supply and single radiation pattern (single line) clock frequency.(Clock is generated by cave in peripheral chip 8284). 6) 8086 comes with diverse versions. 8086 runs at 5 MHz, 8086-2 runs at 8 MHz, 8086-1 runs at 10 MHz. 7) It comes in 40-pin configuration with HMOS engine room having around 20,000 transistors in its circuitry. 3/9/2006 Y.H.Dandawate 3 Features Continued 8) It has multiplexed address and data bus kindred 8085 due to which the pin look is reduced considerably. 9) Higher Throughput (Speed) (This is achieved by a model battle cryed pipelining).

right away 8086 is no longer used. unless the concept of its principles and structures is very useful for instinct other ripe Intel microprocessors. 3/9/2006 Y.H.Dandawate 4 Pin diagram of 8086 3/9/2006 Y.H.Dandawate 5  subjective Architecture of 8086 Architecture of 8086 (contd..) channelize the next centering term current instruction is beneath execution is called pipelining. What happens to stand up when jump or call instruction is executed ? When 8086 is adapt the contents of IP be 0000 H and contents of CS are FFFF H. Other registers are cleared to 0000 h. 3/9/2006 Y.H.Dandawate 7...If you want to get a full essay, order it on our website: Orderessay
