Test: High Level Optimization - Computer Science Engineering (CSE) MCQ

Explanation: Certain tools are available which are developed for the optimization programmes and one such tool is the FRIDGE or fixed-point programming design environment, commercially made by Synopsys System Studio.

Explanation: There are certain tools available which are developed for the optimization programmes and one such tool is the FRIDGE or fixed-point programming design environment, commercially made available by Synopsys System Studio. This tool can is used in the transformation program, that is the conversion of floating point arithmetic to the fixed point arithmetic. This is widely used in the signal processing.

Explanation: The FRIDGE tool uses C programming algorithm in the initial stage and is converted to a fixed-C algorithm which extends C by two extends.

Explanation: Many loop transformation are done for the optimization of the program and one such loop transformation is the loop fusion in which a single loop is split and the loop fission includes the merging of the two separate loops.

Explanation: The loop unrolling is a standard transformation which creates several instances of the loop body and the number of copies of the loop is known as the unrolling factor.

Explanation: The number of copies of the loop is known as the unrolling factor and it is a standard transformation that produces instances of the loop body

Explanation: The loop unrolling can reduce the loop overhead, that is the fewer branches per execution of the loop body, which in turn increases the speed but is only restricted to loops with a constant number of iteration. The unrolling can increase the code size.

Explanation: The loop unrolling can decrease the loop overhead, the fewer branches per execution of the loop body and this can increase the speed but is only restricted to loops with a constant number of iteration and thus the loop unrolling can increase the code size.

Explanation: As the memory size decreases, it is faster in operation, that is the smaller memories are faster than the larger memories. The small memories are caches and the scratch pad memories.

Explanation: The loop tiling can reduce the energy the consumption of the memory systems.
