Each instruction in ARM machine is encoded into...........wordSelect one:a.  2 Byteb. 8 Bytec. 16 Byted. 4 Byte

Break Down the Problem

1. Identify what type of encoding is used for ARM machine instructions.
2. Determine the size of the encoded instruction word.

Relevant Concepts

• ARM architecture commonly uses fixed-length instruction encoding.
• Typically, the size of an instruction word in ARM architecture is crucial for understanding its operation.

Analysis and Detail

• ARM instructions are typically 32 bits in length.
• Since 1 Byte = 8 bits, a 32-bit instruction would be: $\text{Size in Bytes} = \frac{32 \text{ bits}}{8 \text{ bits per Byte}} = 4 \text{ Bytes}$

Verify and Summarize

• The calculation confirms that each instruction in ARM is encoded into a 4 Byte word.

Final Answer

d. 4 Byte
