In this paper, we study the memory allocation problem in data path synthesis. We propose a register organization called circular FIFO as an alternative to register file organization. In comparison with register file organization, FIFO organization eliminates the overhead of address generation and decoding hardware. The memory allocation problem, based on the circular FIFO organization, has been...

Constructing flash memory based storage, FTL (Flash Translation Layer) manages mapping between logical address and physical address. Since FTLwrites everydata to new region by itsmappingmethod, the previous data is not overwritten by new write operation. When a journaling file system is set up upon FTL, it duplicates data between the journal region and its home location for the file system cons...

Problem statement: In multihomed host, if data transfer starts using CMT, unaware of paths status causes delay in data transfer or packet loss due to path failure. Transmission Path (one or more paths) failures result in out-of-order data delivery causing receiver buffer blocking and preventing sender from transmitting further data. Approach: Multipath State Aware Concurrent Multipath Transfer ...

INTRODUCTION The aim of this study was to compare the cyclic fatigue resistances of nickel-titanium rotary glide path files, which are manufactured as single-file systems, under dynamic model. METHODS Twenty ProGlider (16.02) and 20 One G (14.03) nickel-titanium glide path files were included in this study. Cyclic fatigue tests were performed with specifically manufactured dynamic cyclic test...

The file system provides the mechanism for online storage and access to file contents, including data and programs. This paper covers the high-level details of file systems, as well as related topics such as the disk cache, the file system interface to the kernel, and the user-level APIs that use the features of the file system. It will give you a thorough understanding of how a file system wor...

introduction: the aim of this in vitro study was to evaluate the effect(s) of three canal lubricants i.e. sodium hypochlorite, rc-prep as the paste form of ethylenediaminetetraacetic acid (edta) and aqueous edta, on the occurrence/incidence of fracture, deformity and metal slivering of protaper rotary instruments. methods: a total of 120 mesial canals ( i.e. mesiobuccal and mesiolingual) of fir...

This a description and user guide for an object oriented toolbox written in matlab for computations defined on Grassmann manifolds and products of Grassmann manifolds. It implements basic operations as geodesic movement and parallel transport of tangent vectors. 1 Content of toolbox There are two classes: • @grass — Contains functions, methods and operations for objects on one Grssmannian. • @p...

Fast, byte-addressable NVM promises near cache latency and near memory bus throughput for file system operations. However, unanticipated cache line eviction may lead to disordered metadata update and thus existing NVM file systems (NVMFS) use synchronous cache flushes to ensure consistency, which extends critical path latency. In this paper, we revisit soft updates, an intriguing idea that elim...

In this paper, we present DupeFile, a simple yet critical security vulnerability in numerous file systems. By exploiting DupeFile, adversary can store two or more files with the same name/path, with different contents, inside the same volume. Consequently, data-exfiltration exploiting DupeFile vulnerability, hereafter called DupeFile Hiding, becomes simple and easy to execute. In DupeFile Hidin...
