Abstract

Due to the advance of hardware, various devices have mobility features, and many applications need the data transmission. In addition, it is essential for latest smartphones to utilize multi-cores and multi-threads because of the enhancement of Application Processor. Therefore, this paper analyzes the performance/power consumption according to transmission rate, the number of cores, and that of threads in the system that is supposed to conduct data transmission and processing simultaneously. Through the analysis, this paper provides a direction for the proper number of threads in terms of performance improvement and efficient power consumption.

하드웨어의 발전으로 많은 기기가 휴대화 됨에 따라 많은 어플리케이션이 데이터 송수신을 필요로 하게 되었다. 또한 Application Processor (AP)의 발전으로 인해 스마트폰에서도 멀티 코어 및 멀티 쓰레드의 활용이 필수가 되었다. 따라서 본 논문은 데이터 송수신과 프로세싱이 동시에 이루어지는 시스템에서 다양한 데이터 통신 속도, 코어 수, 쓰레드 수를 활용하여 성능을 평가 하고 전력 소모를 분석하였으며, 성능 향상과 효율적인 전력소모 측면에서의 적절한 쓰레드 수를 결정할 수 있는 방향을 제시한다.
