Q9:2. Before starting this part of the lab, please do all calculations below manually. Create a new project: Lab5b. Copy the appropriate files over from the provided zip file. Starting with provided calculate.s, modify it to add or subtract the numbers that are stored in the memory and store the sum in memory (i.e. your program should read numbers from the memory, apply mathematical operation to the numbers accordingly and save the result in the memory).

Q14: A microprocessor has an instruction set that consists of 135 instructions, where each instruction consists of opcode and two operands - each operand is 20 bits. Each instruction needs fetch, decode, read operand, execute, write, and interrupt stage Assume that as an average, each stage requires three micro-operations to complete. Also, assume that the control memory is N bits wide (i.e., control field bits + address selection field bits + address bits - N bits). The control field bits are 12, and there are 7 flags to be monitored. a. How many bits are needed in the address field? (3 points) b. What is the size of control buffer register? (3 points) c. What is the size of control address register? (3 points) d. What is the size of control memory, in bytes? (4 points) e. What is the size of instruction register? (3 points) f. In order to change this to two-address format, what parameter(s) are to be changed, and how? (4 points) Consider the following code. Draw a pipeline diagram with total clock cycles needed using instruction pipeline (FI, DI, FO, EI, WO). Assume that system has two memory ports, and A, B, C, D are values stored in memory.

Q15:12 m IM Ve 3 me $ -- -- I have a project in Proteus using PIC18F46K22 that consists of 16 oil wells, and the power supply is 5V DC. I have represented each oil well with a variable resistor (10k ohm), and now I have 16 variable resistors as inputs connected to the ADC pins. Then, the oil flow level is displayed on an LCD screen (16x2) (LM016L), and also an active buzzer is connected to the PIC18F46K22. The requirement: Based on the connections shown in the image, write the code and the required initializations for the LCD and PIC18F46K22 using MPLAB X IDE development environment to measure the flow of each oil well. It should display the well number along with its flow level as a percentage on the LCD screen for five seconds, then move to the next well for 5 seconds, and so on until it reaches well 16 and then stops. When there is no oil flow for a well, the buzzer should sound and "No flow" should be written on the screen. Some important instructions: 1. The code written using the MPLAB X IDE program only. 2. Submit the code by attaching the MPLAB X IDE files. 3. The code is written while adhering to the connections shown in the figure only. 4. The Proteus (simulation) file has been attached and there is no need to build the connections again. RSee Answer
Q16:Exercise 1 Provide the values of the Carry Flag (CF), Zero Flag (ZF), and the Sign Flag (SF) corresponding to each of the following arithmetic operations. Assume a 32 bits processor: OXCDAAACDF + 0xFABC1BCD 0x3DAAA1FF-0x9ACD4AB1 OxABCD12CF + 0x1245C122 OxCDFFB222 + 0xFFFF Notes: 1- As was mentioned in the class, each flag can take two possible values only: 1 or 0 if the event takes place or not respectively. For instance, if there is carry, then CF = 1. Otherwise CF = 0 2- As a reminder, a number is negative if its most significant bit is 1. In this case, SF flag = 1See Answer
