Apabila teknologi semakin berkurangan, tenaga kebocoran menyumbang kepada bahagian yang lebih besar daripada jumlah tenaga. Mengaplikasikan mengantuk teknik ke cache, dianggap sebagai salah satu teknik yang paling berkesan untuk mengurangkan tenaga kebocoran. Walau bagaimanapun, ia meningkatkan Kadar Ralat Lembut (SER), justeru, ramai penyelidik meragui kebolehpercayaan teknik mengantuk. Dalam makalah ini, kami menunjukkan beberapa sebab mengapa cache arahan boleh mengamalkan teknik mengantuk tanpa masalah kebolehpercayaan. Pertama, cache arahan sentiasa menyimpan data baca sahaja, yang membawa kepada pemulihan ralat lembut dengan mengambil semula arahan daripada memori peringkat bawah. Kedua, kesan pengambilan semula yang disebabkan oleh ralat lembut pada prestasi adalah diabaikan. Selain itu, peratusan besar ralat lembut boleh berlaku tanpa menjejaskan prestasi. Akhir sekali, ralat lembut yang tidak boleh dipulihkan boleh dikawal oleh menyental kaedah. Keputusan simulasi menunjukkan bahawa cache arahan yang mengantuk jarang meningkatkan kadar ralat yang tidak dapat dipulihkan dan merendahkan prestasi secara diabaikan.

Abstract: As technology scales down, leakage energy accounts for a greater proportion of total energy. Applying the drowsy technique to a cache, is regarded as one of the most efficient techniques for reducing leakage energy. However, it increases the Soft Error Rate (SER), thus, many researchers doubt the reliability of the drowsy technique. In this paper, we show several reasons why the instruction cache can adopt the drowsy technique without reliability problems. First, an instruction cache always stores read-only data, leading to soft error recovery by re-fetching the instructions from lower level memory. Second, the effect of the re-fetching caused by soft errors on performance is negligible. Additionally, a considerable percentage of soft errors can occur without harming the performance. Lastly, unrecoverable soft errors can be controlled by the scrubbing method. The simulation results show that the drowsy instruction cache rarely increases the rate of unrecoverable errors and negligibly degrades the performance.
