QUESTION: 1

 VLIW stands for

Solution:

Answer: a
Explanation: It is the architecture designed to perform multiple operations in parallel.

QUESTION: 2

The important feature of the VLIW is _______

Solution:

Answer: a
Explanation: ILP stands for Instruction Level Parallelism.

QUESTION: 3

The main difference between the VLIW and the other approaches to improve performance is

Solution:

Answer: c
Explanation: The Pipe-lining and super-scalar architectures involved the usage of complex hardware circuits for the implementation.

QUESTION: 4

 In VLIW the decision for the order of execution of the instructions depends on the program itself. 

Solution:

Answer: a
Explanation: In other words the order of execution of instructions has nothing to do with the physical hardware implementation of the system.

QUESTION: 5

The parallel execution of operations in VLIW is done according to the schedule determined by _____

Solution:

Answer: c
Explanation: The compiler first checks the code for inter dependencies and then determines the schedule for its execution.

QUESTION: 6

The VLIW processors are much simpler as they don not require of _____

Solution:

Answer: d
Explanation: As the compiler only decides the schedule of execution the scheduler is not required here.

QUESTION: 7

The VLIW architecture follows _____ approach to achieve parallelism.

Solution:

Answer: d
Explanation: The MIMD stands for Multiple Instructions Multiple Data.

QUESTION: 8

The following instruction is allowed in VLIW:
f12 = f0 * f4, f8 = f8 + f12, f0 = dm(i0, m3), f4 = pm(i8, m9);

Solution:

Answer: a
Explanation: The above mentioned instruction is a complex 48 bit instruction used to perform operations on floating numbers.

QUESTION: 9
