- Most Intel CPUs use the __________, in which each memory address is represented by two integers.The time it takes to perform the fetch instruction and decode instruction steps is called the execution time. True or false?A(n) ________________ instruction always alters the instruction execution sequence. A(n) ______________ instruction alters the instruction execution sequence only if a specified Condition is true.

DS = 0200H, BX = 0300H, and DI-400H Determine the memory address accessed by each of the following instructions, assuming real mode operation: (1) MOV AL,[1234H] (2) MOV AX,[BX] (3) MOV [DI]ALQ2- Write a program in assembly language for the 8085 microprocessor to receive one byte of data via the SID and store it at the memory address (3000H to 3009H) using a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz . When receive the required bytes, you must adhere to the following: The bits of two high bits will be received at the beginning of the reception(start bits 1 1 ), after that the data bits will be received, after that the low bit of the stop bit will be received (stop bit 0 ). The following flowchart will help you. The solution must be integrated and include the calculation of the baudrate delay timeOn a typical microprocessor, a distinct I/O address is used to refer to the I/O data reg- isters and a distinct address for the control and status registers in an I/O controller for a given device. Such registers are referred to as ports. In the Intel 8088, two I/O in- struction formats are used. In one format, the 8-bit opcode specifies an I/O operation; this is followed by an 8-bit port address. Other I/O opcodes imply that the port ad- dress is in the 16-bit DX register. How many ports can the 8088 address in each I/O addressing mode? .
- A microprocessor has an increment memory direct instruction, which adds 1 to the value in a memory location. The instruction has five stages: fetch opcode(four bus clock cycles),fetch operand address (three cycles), fetch operand (three cycles) add 1 to operand (three cycles), and store operand (three cycles). a. By what amount (in percent) will the duration of the instruction increase if we have to insert two bus wait states in each memory read and memory write operation? b. repeat assuming that the increment operation takes 13 cycles instead of 3 cyclesQuestion 6 Suppose you have a RISC machine with a 1.6 GHz clock (i.e., the clock ticks 1.6 billion times per second).
