Many countries in the word have loose and unstable soils encompassing a wide range ofgeological materials, which when inundated, may collapse and cause very significant distress to the structure. Stone columns have been used to strengthen such soils; even so, there are still cases where failure has occurred. In this technical note, the process and causes of stone column failure in reinforcing c...

L1 cache design contributes significantly to the performance and energy consumption of microprocessors due to L1’s large proportion of die size and high activity factor. Voltage reduction reduces energy per operation, however, increased process variability in modern technology nodes causes an exponential growth in SRAM failure probability for linear voltage reduction, necessitating some form of...

We propose a novel two-layer error control code, combining error detection capability of rectangular codes and error correction capability of Hamming product codes in an efficient way, in order to increase cache error resilience for many core systems, while maintaining low power, area and latency overhead. Based on the fact of low latency and overhead of rectangular codes and high error control...

today power consumption is considered to be one of the important issues. therefore, its reduction plays a considerable role in developing systems. previous studies have shown that approximately 50% of total power consumption is used in cache memories. there is a direct relationship between power consumption and replacement quantity made in cache. the less the number of replacements is, the less...

CPU flush instruction-based cache side-channel attacks (cache instruction attacks) target a wide range of machines. For instance, Meltdown / Spectre combined with FLUSH+RELOAD gain read access to arbitrary data in operating system kernel and user processes, which work on cloud virtual machines, laptops, desktops, mobile devices. Additionally, fault injection use cache. Rowhammer, is attack that...

conclusions: the results of the present research indicates that the emphasis of the his evaluation moves from technical subjects to human and organizational subjects, and from objective to subjective issues. therefore, this issue entails more familiarity with more qualitative evaluation methods. in most of the reviewed studies, the main focus has been laid on the necessity of using multi-method...
