MP&MC KEY

1.      8-10 MHz is the Maximum clock frequency in 8086.

2.      The two pins are used because the Pin +VCC provides the power supply to it and GND pin is used to earth the pin so no voltage breakdown is there.

3.      In 8086 carry flag, Parity flag, Auxiliary carry flag, Zero flag, Overflow flag, Trace flag, Interrupt flag, Direction flag, and Sign flag.

4.      FIFO (First in First Out) stack is used in 8086.In this type of Stack the first stored information is retrieved first.

5.      Maskable interrupts Non-Maskable interrupts.

6.      SIM is Set Interrupt Mask. Used to mask the hardware interrupts. RIM is Read Interrupt Mask. Used to check whether the interrupt is Masked or not.

7.      Bus Interface Unit and Execution unit, are the two different functional units in 8086.

8.      The BIU in 8088 is 8-bit data bus & 16- bit in 8086.Instruction queue is 4 byte long in 8088and 6 byte in 8086.

9.      8085 is a 8 bit microprocessor
8086 is a 16 bit microprocessor.

10.  Interpreter is the tool used to connect the user and the tool.

11.  8088 is that processor.

12.  Trap is known as Non-Maskable interrupts, which is used in emergency condition.

13.  Code, Data, Stack, Extra Segment registers in 8086.

14.  A program runs on one machine and executes on another is called as cross-compiler.

15.  Stack Segment in segment register is used to store interrupt and subroutine return address registers.

16.  Execution Unit receives program instruction codes and data from BIU, executes these instructions and store the result in general registers.

17.  Z80, Intel MSC51 &96, Motorola are the best examples of Microcontroller.

18.  Non-Maskable interrupts are used in critical events. Such as Power failure, Emergency shut off etc.

19.  An interrupt which can be never be turned off (ie.disabled) is known as Non-Maskable interrupt

20.  Forward Error Correction is a method by which Bluetooth increases its noise immunity. FEC is a method that enables a receiver to not only detect, but also correct errors in a transmission.

21.  8086 is used for general purpose like it is used in traffic signals for control purpose .It also used for small applications like for calculator, etc scientific calculators & small arithmetic operations.

22.  RST 7.5 003C H
RST 6.5 0034 H
RST 5.5 002C H
TRAP 0024 H

23.  Single slave, Master slave, Scatternet.

24.  An interrupt that can be turned off by the programmer is known as Maskable interrupt.

25.  8086 is having 2 different units i.e. BIU (Bus Interface Unit) and EU (Execution Unit), these two units work synchronously.

26.  Accumulator is the register in which Arithmetic and Logic calculations are done.

27.  Frequency hopping is the technology used in Bluetooth.

28.  memory size of 8086 is 1MB memory size of 8085 is 64KB 2 ^(adresslines)=size of memory (bytes) so address lines of 8086 are 20 and 8085 is 16

29.  The address line is 02 greater than the earlier value.

30.  The address line is 02 less than the earlier value.

31.  8088 is that processor.

32.  Instruction pointer, 4-segment registers, IQ

33.  STI,CLI

34.  8

35.  20

36.  16

37.  80286,80386,ARM

38.  For generating clock frequency

39.  16

40.  The address bus unidirectional because the information on the address bus is always provided by the microprocessor.

41.  2

42.  Duty cycle = t_on / t_total

43.  Address pins, data pins, clock pins, rst, vcc, gnd, txd, rxd, rtc, ctc, etc.,

44.  The data is to move from or to memory or I/O devices.

45.   UART send the information in Synchronously

USART sends the information in asynchronous and Synchronous

46.  In synchronous sends only data blocks

In asynchronous sends only by data characters/bits

47.  Simplex, half duplex, full duplex.

48.  Micro processor

49.  Macros are processed by assembling time and procedures are processed by execution time.

50.   Bus is a collection of signal lines
