Suppose you have an Intel 8086 Microprocessor which is running at a frequency of 50 MHz. Now what is the maximum number of times it can read a byte of data from the memory in 3 seconds? 12500000 37500000 1250000 3750000 Suppose an Intel 8086 Microprocessor is operating at 8 MHz. Which of the following statements are true? ] The clock cycle is 125 ns | In each bus cycle, the clock remains high for 41.25 ns Data is supplied during the 250 ns to 375 ns period in a bus cycle. While reading, ALE stays high during the 125 ns to 250 ns period in a bus cycle. The Status Bus bits becomes available before 250 ns in a bus cycle.
Assume a CPU with a fixed 32-bit instruction length has the following instruction format:opcode mode [operand1] [operand2] [operand3]The mode encodes the number of operands and each operand’s mode. For instance, one mode indicates three registers, another indicates two registers and an immediate datum, another indicates a main memory reference, etc. Assume there are 94 instructions and 22 modes. Answer the following.a. One mode indicates three registers. How many registers can be referenced in this mode?b. One mode indicates two registers and an immediate datum in two’s complement. Assuming there are 32 registers, what is the largest immediate datum that can be referenced?c. One mode has a destination register and a source memory address (an unsignednumber). Assuming 16 registers, what is the largest memory reference available?d. One mode has two memory addresses, both using base displacement. In both, the basesare stored in index registers and the displacements are specified in the…
Q1- Write a program in assembly language for the 8085 microprocessor to send one byte of data located at the memory address (3000H) using SOD at a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz. When sending the required byte, you must adhere to the following: The two high bits of the start bits must be sent, after that the data bits are sent, after that the low bit of the stop bit is sent. The following flowchart will help you. The solution must be integrated and include the calculation of the baud rate delay time Transmit Set up Character Bit Counter • Send Start Bit No Wait Bit Time Get Character in Accumulator Output Bit Using Do Wait Bit Time Rotate Next Bit in Do Decrement Bit Counter Is It Last Bit? Yes • Add Parity if Necessary Send Two Stop Bits Return (a)
Q1- Write a program in assembly language for the 8085 microprocessor to send 10 bytes of data located at the memory address (3000H to 3009H) using SOD at a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz. When sending each of the required bytes, you must adhere to the following: The two high bits of the start bits must be sent, after that the data bits are sent, after that the low bit of the stop bit is sent. The following flowchart will help you, but you should notice that this flowchart deals with one byte, and you are required to deal with 10 bytes.

Q1/ Two word - wide unsigned integers are stored at the physical memory addresses 0400H and 0402H respectively. Write an instruction sequence that computes and stores their sum, difference, product, and quotient. Store these results at consecutive memory locations starting at physical address 0410H in memory. To obtain the difference, subtract the integer at 0402H from the integer at 0400H. For the division, divide the integer at 0400H by the integer at 0402H. Use the register indirect relative addressing mode to store the various result.

The following byte sequence is the machine code of a program function compiled with the Y86- 64 instruction set. The memory address of the first byte is 0x300. Note that the byte sequence is written in hex-decimal form, i.e., each number/letter is one hex-decimal number representing 4 binary bits, and two numbers/letters represent one byte. 630030F3020000000000000030F11E000000000000007023030000000 00000601061316211761F0300000000000090- Please write out the assembly instructions (in Y86-64 instruction set) corresponding to the machine codes given by the above bytes sequence, and explain what this program function is computing. The machine has a little-endian byte ordering.

Translate the following pseudo code into MIPS assembly to show each of the addressing modes covered in this chapter. Note that variables x and y are static and volatile, so should be stored in data memory. When using register direct access, you do not need to store the variables in memory. main() { static volatile int miles = prompt("Enter the number of miles driven: "); static volatile int gallons = prompt("Enter the number of gallons used: "); static volatile int mpg = miles / gallons; output("Your mpg = " + mpg);}
52-Two word wide unsigned integers are stored at the physical memory addresses 00A00 and 00A02, respectively. Write an instruction sequence that computes and stores their sum, difference, product, and quotient. Store these results at consecutive memory locations starting at physical address 00A 10 in memory. To obtain the difference , subtract the integer at 00A02 from the integer at 00A00. For the division divide the integer at 00A00 by the integer at 00A02.
