9. Write an 8086 assembly language program to sort the given array of numbers in ascending order. The numbers are in the data segment. 15
OR
With the help of a block diagram explain the internal architecture of 8086. With the help of a figure explain how 8259A can be connected in a system containing one master and eight slaves (maximum) to handle upto 64 priority levels and explain how interrupts is serviced in this system.
OR
Draw and explain the interfacing of DMA controller 8257 with 8086 so that the channel0 DMA address register has an l/O address 80 H and mode set register has an address 88 H. lnitialize the 8257 with normal priority, TC stop and non-extended write.
