The number −6 can be represented as 1010 in 4-bit 2’s complement representation. Which of the following is/are CORRECT 2’s complement representation(s) of −6?

1000110 in 8-bits
11111010 in 8-bits
1000000000001010 in 16-bits
1111111111111010 in 16-bits

Correct answer: 11111010 in 8-bits

Solution

The correct option, 11111010 in 8-bits, accurately represents -6 in 2's complement form, as it is derived by inverting the binary representation of +6 (00000110) and adding 1, resulting in 11111010.

Suppose a program is running on a non-pipelined single processor computer system. The computer is connected to an external device that can interrupt the processor asynchronously. The processor needs to execute the interrupt service routine (ISR) to serve this interrupt. The following steps (not necessarily in order) are taken by the processor when the interrupt arrives: (i) The processor saves the content of the program counter. (ii) The program counter is loaded with the start address of the ISR. (iii) The processor finishes the present instruction. Which ONE of the following is the CORRECT sequence of steps?
