We consider the automatic determination of application-specific memory subsystems via superoptimization, with the goals of reducing memory access time and of minimizing writes. The latter goal is of concern for memories with limited write endurance. Our subsystems outperform general-purpose memory subsystems in terms of performance, number of writes, or both.

in this study, generation of the transient evoked ooacoustic emissions in human ear has been simulated using a new electroacoustic model. the method of state variables was adopted to calculate the auditory model, and numerical integration methods have been used to solve differential equations in matlab. simulation results have been compared with the real data. in this study, latency curves, fre...

Synchronous small writes play a critical role in the reliability and availability of file systems and applications that use them to safely log recent state modifications and quickly recover from failures. However, storage stacks usually enforce page-sized granularity in their data transfers from memory to disk. We experimentally show that subpage writes may lead to storage bandwidth waste and h...

VFS lookup code examines and translates path names one component at a time, checking for special cases such as mount points and symlinks. VFS calls the NFS lookup operation as necessary. NFS employs caching to reduce the number of lookup operations that go to the server. However , when part or all of a path is not cached, NFS lookup operations go back to the server. Although NFS's caching is ee...
