If a system's instruction set consists of an 8-bit opcode, what is the maximum number of output signal lines required for the co
otez555 [7]

Answer:

D. 256

Explanation:

Given

Instructions = 8\ bit

Required

Determine the maximum number of output

To get the required value, we make use of the following:

Maximum = 2^n

Where n is the bits of the opcode.

i.e.

n = 8

Substitute 8 for n in Maximum = 2^n

Maximum = 2^8

Maximum = 256

<em>Hence, option D answers the question</em>
