Test: Compilers - Computer Science Engineering (CSE) MCQ

Explanation: The compilers can reduce the energy consumption of the embedded system and the compilers performing the energy optimizations are available.

Explanation: There are several reasons for designing the optimization and compilers and one such is that it could help to meet and prove the real-time constraints.

Explanation: Saving energy can be done at any stage of the embedded system development. The high-level optimization techniques can reduce the power consumption and similarly compiler optimization also can reduce the power consumption and the most important thing in the power optimization are the power model.

Explanation: Tiwari proposed the first power model in the year 1974. The model includes the so-called bases and the inter-instruction instructions.Base costs of the instruction correspond to the energy consumed per instruction execution when an infinite sequence of that instruction is executed. Inter instruction costs model the additional energy consumed by the processor if instructions change.

Explanation: The third model was proposed by Russell and Jacome in the year 1998.

Explanation: The third model was proposed by Russell and Jacome in the year 1998 and is based on the precise measurements of the two fixed configurations.

Explanation: The smaller memories provides faster access and consume less energy per access and SPM or scratch pad memories is a kind of small memory which access fastly and consume less energy per access and it can be exploited by the compiler.

Explanation: The encc-energy aware compiler uses the energy model by Steinke et al. it is based on the precise measurements of the real hardware. The power consumption of the memory, as well as the processor, is included in this model.

Explanation: The knapsack problem is associated with the size constraints, that is the size of the scratch pad memories. This problem can be solved by one-to-one mapping which was presented in an integer programming model by Steinke et al.

Explanation: The CACTI can compute the power consumption of the cache which is proposed by Wilton and Jouppi in the year 1996.
