Design the instruction formats for the following instruction set using an expanding opcode. The size of all instructions is 32 bits, all register numbers are 4 bits, memory addresses are 20 bits, and the displacement field is 16 bits. For each category of instructions, show the instruction format, what fields it has, and the number of bits in each field. Also show the range of values for the opcode for each instruction category. • 15 instructions with two register numbers and one memory address
• 15 instructions with one register number and one memory address
• 60 instructions with one register number and one displacement
• 15 instructions with one displacement

Write a pseudocode solution for each of these problems. 1. design a while loop that lets that user enter a number. the number should be multiplied by 10, and the result stored in a variable named product. the loop should iterate as long as product contains a value less than 100. 2. design a do-while loop that asks the user to enter two numbers. the numbers should be added and the sum displayed. the loop should ask the user whether he or she wishes to perform the operation again. if so, the loop should repeat; otherwise it should terminate. 3. design a for loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 100. 4. design a nested loop that displays 10 rows of # characters. there should be 15 # characters in each row. 5. convert this for loop to a while loop. declare integer count for count = 1 to 50 display count end for 6. find the error in the following pseudocode. declare boolean finished = false declare integer value, cube while not finished display “enter a value to be cubed.” input value; set cube = value ^ 3 display value, “ cubed is “, cube end while

In a game with three frames, where will the objects on layer 1 appear? a. next to the play area b. in the middle of the game c. behind everything else d. in front of everything else

Ac++an of of pi. in , pi is by : pi = 4 – 4/3 + 4/5 – 4/7 + 4/9 - 4/11 + 4/13 - 4/15 + 4/17 . ., to pi (9 ). , if 5 to pi,be as : pi = 4 - 4/3 + 4/5 - 4/7 + 4/9 = 4 – 1. + 0.8 - 0. + 0. = 3.. atoofbe to pi?
