제목	Technical Review: Cache Scheme of Shared-Buffer Mappings for Energy-Efficiency of Mobile Devices
궁금했던 점	Application-device shared buffer의 반복 map/unmap 비용, 특히 fragmented physical address space에서의 CPU 및 energy 비용을 줄일 수 있는가?
해본 것	동일 shared buffer를 다시 사용할 때 활용하도록 mapping information을 cache한다.
당시 조건	Verification level: official_abstract. Sources checked: https://doi.org/10.1049/el.2015.0244 https://yonsei.elsevierpure.com/en/publications/cache-scheme-of-shared-buffer-mappings-for-energy-efficiency-of-m/
실제 결과	상용 smartphone system 대비 video playback 중 processor utilization 약 64%, energy consumption 약 17% 감소를 보고한다.
왜 그랬는지	3쪽짜리 letter이며 공개 초록은 기기, buffer allocator, fragmentation 시나리오와 cache invalidation 비용을 상세히 제공하지 않는다. Technical interpretation: Data 자체뿐 아니라 비싼 address-translation 또는 mapping 결과도 identity와 lifetime이 안전하다면 재사용할 수 있다.
다음에 기억할 것	Data 자체뿐 아니라 비싼 address-translation 또는 mapping 결과도 identity와 lifetime이 안전하다면 재사용할 수 있다.
언제 맞는지	Multimedia buffer를 application과 device가 반복 공유하는 mobile SoC에 해당한다.
신뢰도	중간
