碩士 === 國立中正大學 === 資訊工程研究所 === 104 === Most embedded systems belong to the ARM architecture formula embedded systems, low energy consumption typically support only Suspend to RAM (STR) this power management mechanism, generally does not go to implement such a mechanism Suspend to Disk (STD) but since the study SHI-WU,LO, fast boot is based on Suspend to Disk(STD) , the system must be done for STD support to achieve the sleep type fast boot function. Therefore, this paper made a hypothesis, assuming that the system which is able to STR must be able to STD, because the macro to run these two mechanisms, the biggest difference is that, STD need to store main memory data to an external storage, restore when data is written back to memory again, as long as the preservation of data integrity enough, the system will readily support this STD power management mechanism. This paper focus on these two mechanisms (STR, STD) made a detailed presentation and comparison, and use an example to prove the above assumption.
