QI) If BX=1000, DS=0200, SS=0100, CS-0300 and AL=EDH, for the following instruction: MOV [BX] + 1234H, AL. Find the physical address in the memory. Q2) For the above question, if BP is used instead of BX, what is the physical address in the memory?
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…
7. For both of the instructions shown below, the initial conditions are shown. The result (which the instruction stores in r1) is also shown. For each instruction, answer these questions: • What is the state of the flags (NZCV) after the instruction executes • If the operands were signed, are the results valid? Why or why not? • If the operands were unsigned, are the results valid? Why or why not? a) initial conditions: r0 = 0xAAAA_AAAA rl=0x5555_5555 ADDS rl,rl,ro Result: r1=0xFFFF_FFFF b) initial conditions: r0=0x7FFF_FFFD r1 = 0x0000_000F ADDS rl,ro,r1 Result: r1=0x8000_000C

Suppose that you have a computer with a memory unit of 24 bits per word. In this computer, the assembly program's instruction set consists of 198 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. a. How many bits are needed for the opcode? b. How many bits are left for the address part of the instruction? c. How many additional instructions could be added to this instruction set without exceeding the assigned number of bits? Discuss and show your calculations.
