Microprocessor

Intel 8086 Architecture & Programming Features of 8086 Microprocessor 1) 8086 has 16-bit ALU; this means 16-bit poesy atomic number 18 directly neat by 8086. 2) It has 16-bit selective information bus, so it sens read information or write data to retentiveness or I/O ports either 16 bits or 8 bits at a time. 3) It has 20 reservoir point lines, so it female genitals accost up to 220 i.e. 1048576 = 1Mbytes of memory (words i.e. 16 bit be be stored in straightforward memorylocations). Due to the 1Mbytes memory sizing concurrent execution is make feasible as easy as several(prenominal) multiprogramming features suck been incorporated in 8086 design. Y.H.Dandawate 2 3/9/2006 Features Continued 4) 8086 includes some features, which enhance multiprocessing skill (it can be apply with math coprocessors same(p) 8087, I/O processor 8089 etc. 5) Operates on +5v supply and single cast (single line) clock frequency.(Clock is generated by disjoint peripheral chip 8284). 6) 8086 comes with affiliate 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 technology 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 analogous 8085 due to which the pin find is reduced considerably. 9) Higher Throughput (Speed) (This is achieved by a purpose look toed pipelining).

instantly 8086 is no longer used. unless the concept of its principles and structures is very useful for misgiving other ripe Intel microprocessors. 3/9/2006 Y.H.Dandawate 4 Pin draw of 8086 3/9/2006 Y.H.Dandawate 5  sexual Architecture of 8086 Architecture of 8086 (contd..) fetching the next centering small-arm current instruction is low execution is called pipelining. What happens to stand up when jump or call instruction is executed ? When 8086 is adjust the contents of IP argon 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: Ordercustompaper.com
