1. Given the register contents, answer the following: [5+5] a. what physical address will the next instruction be fetched from ? Hints: instructions are located in code segment b. What is the physical address for the top of the stack? Hints: current value of stack pointer refers to the top of the stack segment 2. Write the 8086 instruction which will perform the indicated operation. [10] a. Copy AL to BL. b. Load 43H into CL. c. Increment the contents of c by 1 . d. Copy SP to BP. e. Add 07H to DL. f. Multiply AL times BL. g. Copy AX to a memory location at offset 245AH in the data segment, h. Decrement SP by 1. i. Rotate the most significant bit of AL into the least significant bit position, J. Copy DL to a-memory location whose offset is in BX. k. Mask the lower 4 bits of BL. I. Set the most significant bit of AX to a 1, but do not affect the other bits, m. Invert the lower 4 bits of BL, but do not affect the other bits
