Answer 2

Answer:

To a set of 6th bit in a byte the appropriate instruction id is Two source register identifiers and One destination register identifier

Explanation:

An instruction format defines the different component of an instruction. The main components of an instruction are opcode (which instruction to be executed) and operands (data on which instruction to be executed). Here are the different terms related to instruction format:

• Instruction set size – It tells the total number of instructions defined in the processor.
• Opcode size – It is the number of bits occupied by the opcode which is calculated by taking log of instruction set size.
• Operand size – It is the number of bits occupied by the operand.
• Instruction size – It is calculated as sum of bits occupied by opcode and operands.
• The opcode- As we have instruction set of size 12, an instruction opcode can be identified by 4 bits, as 2^4=16 and we cannot go any less.
• Two source register identifiers- As there are total 64 registers, they can be identified by 6 bits. As they are two i.e. 6 bit + 6 bit.
• One destination register identifier- Again it will be 6 bits.
• A twelve bit immediate value- 12 bit.
