Q1) Answer three only: 1- Give the value of: (+75,-75,-0) in binary: (a) 8-bit sign magnitude representation. (b) 16- bit l's complement representation. (c) 16- bit 2's complement representation. 2- Draw memory and microprocessor contents before and after execution the following instruction: MOV DX , [2233H]; machine code for this instruction is( 8B OE 22 33)H. Suppose DS=1000H, CS-400H , IP=100H, DX=1DE2H, (2233H]=3FH, [2234H)=11H. 3- List the number of data items stored in cach of the following memory devices and the number of bits in each datum: (a) 2K x 8 (b) IK X1 (c) 64K x 4 4- A serial program in two parts A and B for which part A represent 75% while part B represent 25%. What is the overall speed up if: 1-part B is made to run 5 times faster. 2- part A is made to run 2 times faster. Which improvement is better?
