1. What instruction (mov, Idr, Idrb, str, strb) is used to... a. Put a byte from memory into a register b. Put a register value into another register c. Put the address of a label into a register d. Put a register value into a memory address e. Put an immediate into a register 2. Which instruction (move, load, or store) lists the source followed by the destination? 3. What punctuation is used to indicate you're reading the address of a label?

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…

Part 2: Status Flags There are more registers inside of the CPU that we don't have direct access to. One of these is the EFLAGS register. This register holds the values of the flags used in the CPU's operation. Flags are just single bit values that represent the state of the processor - usually 1 means a setting is on or true, and 0 means it is off or false.  If a flag has the value 1, we say the flag is set. If it has the value 0, we say it is clear. "Setting" a flag means setting it's value to 1, and "clearing" a flag means setting its value to 0.  The status flags are flags that show the outcomes of certain operations. These can be used to check the state of the computations and react accordingly. For example, the carry flag is set if the result of an unsigned addition is too large to fit into the same space as the numbers used during the addition. Look at the following addition operation: 11111111 + 00000001 = 100000000 Note that the result of the addition is 9 bits long, even…
