MICROPROCESSORS AND MICROCONTROLLERS - 2 (MPMC) DECEMBER 2011 [EXTC] ELECTRONICS AND TELECOMMUNICATION SEMESTER 6

1. (a)	Design 8086 Microprocessor based system with following specifications :-	12
	(i) 8086 Working at 6MHz
	(ii) 16 KB EPROM using 8 KB Chips
	(iii) 16 KB SRAM using 8 KB Chips.
(b)	Draw the memory organisation of PIC 18 controller and explain.	8
2. (a)	Draw interface diagram of 8086 with 8087 and expalin various interface signals	10
	and working.
(b)	Convert the decimal number 125.125 into short real, long real format of 8087.	10
3. (a)	Explain the interrupt structure of 8086 Microprocessor with respect to 8259 PIC.	10
(b)	Draw the PSW of 8086 and explain setting of different bits with example.	10
4. (a)	Draw and explain interfacing of 8086 with 8255.	10
(b)	Write 8086 based program to transfer n bytes of data from source memory area	10
	to the destination memory area.
5. (a)	With neat diagram explain the different instruction formats of PIC 18 controller.	10
	Also give the comparison of bit size of OPcode for different instructions.
(b)	Draw the flow chart and write assembly language program for PIC 18 controller	10
	to read and write ten bytes from program memory to data memory.
6. (a)	Explain the addressing modes of PIC 18 controller with suitable example.	10
(b)	Discuss the pipeline concept used in PIC 18.	10
7.	Write sort notes on any two of the following :-	20
	(a) Stack related instructions of PIC 18.
	(b) Dual functionality of parallel ports of PIC 18
	(c) String instructions in 8086.
