Question

b) What will we do if the data bus is 16 bits wide and our instruction is 64 bit long, and what will happen if the data bus is 16 bits wide and our instruction is 8 bit long?

Answer 2

Does not fit, fits

Explanation:

• A data bus consists of connected wires and it is used for transporting data within the computer system.
• The number of lines are equal to the width of data bus.
• Each line can transport one bit of information.
• To transfer 64 bits, we need 64 lines.
• If we have a data bus of 16 bits and instruction is 64 bit long, it will take only 16 bits of instruction. The instruction does not fit in the data bus.

• If we have less lines, we will miss the information present in remaining length of the instruction.
• Hence, 64 bits instruction needs a data bus of 64 bits.
• If we have a data bus of 16 bits and instruction is 8 bit long, it will fit it in the data bus.
• It will take 8 bits of instruction and in remaining bits places, 0's are placed.
