1- Repeat the previous example using memory- mapped I/O technique?
Step by step
Solved in 2 steps with 1 images
- 3. State and discuss briefly any TWO (2) techniques for I/O operations.Design a binary multiplier that multiplies two 8-bit binary number by following design rules that shown in class. The Q and B are the two separate 8-bit binary inputs, C is the 3-bit sequence counter and R is the 16-bit result. (Note: Explain the registers that you will use to establish given process.)(Hint: Morris Mano, Computer System Architecture, Chapter 10.6.) QxB B Clock Start -Busy/ReadyChoose the right answer from among the following statements. 1) According to the 80/20 rule, 80 percent of the instructions are performed and only 20 percent of the instructions are generated. 2) The external bus in the von Neumann architecture is only for the purpose of data memory storage.
- Which of the following is true? I. According to the 80/20 rule, 80% of instructions are implemented and 20% are created. II. In von Neumann architecture, the external bus is used completely for data memory. a) Only I is true; b) Only II is true; c) Both I and I are true; d) Neither I nor |l is true.0001 = Load AC from memory 0010 = Store AC to memory 0101 = Add to AC from memory 0011 = Load AC (the accumulator register) from an I/O device 0111 = Store AC to an I/O device With these instructions, a particular I/O device is identified by replacing the 12-bit address portion with a 12-bit device number. Remember that a number ending with a small ‘h’ means the number is a hexadecimal number. What is the hexadecimal string that expresses the following instructions? Load AC from memory location 62h. Add the contents of memory location 451h to AC. Store AC to memory location 8h. Store AC to I/O device number 8h.Explain True/False. Statement - The data transfer between memory and I/O devices using programmed I/O is faster than interrupt driven I/O.
- Which of the following statements is correct? 1) The 80/20 rule asserts that 80% of the instructions are executed and 20% of the instructions are produced. 2) The external bus in von Neumann architecture is exclusively used for data memory.When it comes to interrupt-driven I/O, do you have any background?8. The method which offers higher speeds of I/O transfers is a. Interrupts b. Memory mapping c. Program-controlled I/O d. DMA

Answer all of the following questions: a. Convert -211.5 from decimal to IEEE floating point format. b. Give an Assembly language instruction as an example for each of the following operations: Operation Assembly instruction 1. Loads 16-bit data to a register pair. 2. Move the content of a register toanother register. 3. Load 8-bit data to the Accumulator. 4. Store the content of theAccumulator to a memory location.Exactly what are the distinctions between interrupt-driven I/O and programmable I/O?
