Question Answered step-by-step The addresses assigned to the four registen of the 110 interface of… The addresses assigned to the four registen of the 110 interface of Fig. 11-2 are fqual to the binary equivalent ol U. 13, 14, and 15. Show the external circuit that must be connect? betw?n an &-bit 110 address from the CPU and the CS, RSI, and RSO Inputs olthe Interface. 11·2. Six Interface units of the type shown in Fig. 11-2 ate connect? to a CPU that uses an 110 address of eight bits. Each one of the six chip select (CS) inputs connect? to the is connected to a different address tine. Thus the high-order address tine is CS input ol the first interface unit and the sixth address tine is connected to the CS input of the sixth interface unit. The two low-order address lines are connected to the RSl and RSO of aU six Interface units. Determine the 8-bit address of each register in each interface. U.J. List four peripheral devices that produce an acceptable output for a person to understand. 11-4. Write   your full name in ASCII using eight bits per character with the leftmost bit always 0. Include a space between names and a period ? a middle initial. ‘ 440 CHAPTER ELEVEN Input-Output Organization 11-5. 11-6. 11-7. 11-8. 11-9. 11-10. 11-11. 11-12. 11-13. What is the difference between isolated 110 and memory-mapped 110? What are the advantages and disadvantages of each? Indicate whether the following constitute a control, status, or data transfer commands. a. Skip next instruction if flag is set. b. Seek a given record on a magnetic disk. c. Check if 110 device is ready. d. Move printer paper to beginning of next page. e. Read interface status register. A commercial interface unit uses different names for the handshake lines associated with the transfer of data from the 110 device into the interface unit. The interface input handshake line is labeled STB (strobe), and the interface output handshake line is labeled IBF (input buffer full). A low-level signal on STB loads data from the 110 bus into the interface data register. A high-level signal on IBF indicates that the data item has been accepted by the interface. IBF goes low after an 110 read signal from the CPU when it reads the contents of the data register. a. Draw a block diagram showing the CPU, the interface, and the 110 device together with the pertinent interconnections among the three units. b. Draw a timing diagram for the handshaking transfer. c. Obtain a sequence-of-events flowchart for the transfer from the device to the interface and from the interface to the CPU. A CPU with a 20-MHz clock is connected to a memory unit whose access time is 40 ns. Formulate a read and write timing diagrams using a READ strobe and a WRITE strobe. Include the address in the timing diagram. The asynchronous communication interface shown in Fig. 11-8 is connected between a CPU and a printer. Draw a flowchart that describes the sequence of operations in the transmitter portion of the interface when the CPU sends characters to be printed. Give at least six status conditions for the setting of individual bits in the status register of an asynchronous communication interface. How many bits are there in the transmitter shift register of Fig. 11-8 when the interface is attached to a terminal that needs one stop bit? List the bits in the shift register when the letter W is transmitted using ASCII with even parity. How many characters per second can be transmitted over a 1200-baud line in each of the following modes? (Assume a character code of eight bits.) a. Synchronous serial transmission. b. Asynchronous serial transmission with two stop bits. c. Asynchronous serial transmission with one stop bit. Inlormation is inserted into a FIFO bulfer at a rate of m bytes per second. The information is deleted at a rate of n byte per second. The maximum capacity of the bulfer is k bytes. a. How long does it take for an empty buffer to fill up when m > n? b. How long does it take for a full buffer to empty when m < n? c. Is the FIFO buffer needed if m = n?   Image transcription text4. [20 points] A computer architectneeds to design the pipeline of a newmicroprocessor. She has ... Show more...
