Question
Arrange the following types of machine in descending order of complexity. (A) SISD (B) MIMD (C) SIMD Choose the correct answer from the options given below:
The correct answer is
B, C, A
Under the usual architectural comparison, MIMD is most complex because it coordinates multiple independent instruction and data streams. SIMD shares an instruction stream across multiple data streams, while SISD handles one of each. The descending order is MIMD, SIMD, SISD: B–C–A.

Important Questions from Machine Instructions and Addressing Modes
- Consider a processor P whose instruction set architecture is the load-store architecture. The instruction format is such that the first operand of any instruction is the destination operand.
Which one of the following sequences of instructions corresponds to the high-level language statement $Z = X + Y$ ?
Note: X, Y, and Z are memory operands. R0, R1, and R2 are registers. Consider the following program fragment in assembly language:
mov ax, 0h
mov cx, 0A h
doloop:
dec ax
loop doloop
What is the value of ax and cx registers after the completion of the doloop?
