SENSIBle: A Highly Scalable SENsor DeSIgn for Path-Based Age Monitoring in FPGAs

OPENALEX - Publications

Zana Ghaderi M. Ebrahimi Zainalabedin Navabi Eli Bozorgzadeh Nader Bagherzadeh

This paper proposes a highly scalable sensor design for late transition detection in FPGA based platforms. Transition delays occur because of aging mechanisms such as Biased Temperature Instability(BTI) and Hot Carrier Injection (HCI). We propose clock (SCLK) that is function minimum slack time set paths selected age monitoring. There will be one many sensors are needed an entire FPGA. Our proposed architecture makes it possible single SCLK to shared by all sensors. Additionally, the...

This paper presents a two-step aging-aware methodology for Representative Critical Paths (RCPs) selection from large number of (CPs) in programmable logic devices. First, nomination CPs is based on delay, temperature, and lexicographic function duty cycle switching activity filtering, which are the major causes Bias Temperature Instability (BTI) Hot Carrier Injection (HCI) aging mechanisms. Secondly, RCPs will be selected Fan-out (FO) physical location Logic Blocks (LBs) along CP to decrease...

Prolonging Lifetime of Non-volatile Last Level Caches with Cluster Mapping

OPENALEX - Publications

Morteza Soltani M. Ebrahimi Zainalabedin Navabi

Recently, work has been done on using nonvolatile cells, such as Spin Transfer Torque RAM (STT-RAM) or Magnetic (M-RAM), to construct last level caches (LLC). These structures mitigate the leakage power and density problem found in traditional SRAM cells. However, low endurance of decreases lifetime LLC. Therefore, an effective wear-leveling technique is required tackle this issue. In paper, we propose inter-set algorithm that distributes write traffic all portions cache. Our method based...

LUT Input Reordering to Reduce Aging Impact on FPGA LUTs

OPENALEX - Publications

M. Ebrahimi Rezgar Sadeghi Zainalabedin Navabi

In this article, we propose a fine-grained FPGA aging mitigation method. Our method focuses on Look Up Tables (LUTs) which Boolean functions are mapped. Based our observations, for any configuration, even if it is carefully selected, number of LUT transistors experience severe stress rates. Therefore, an algorithm presented to select several alternative configurations each LUT. Alternative obtained by input reordering. These rotationally loaded into the FPGA. Experimental results shows that...

Selecting Representative Critical Paths for Sensor Placement Provides Early FPGA Aging Information

OPENALEX - Publications

M. Ebrahimi Zainalabedin Navabi

This article proposes a methodology for critical path selection and delay sensor insertion aging monitoring in field-programmable gate arrays (FPGAs). The information can be used to reconfigure FPGAs achieve better performance or wear leveling. To filter out the paths less aggressively, our decides based on both physical-level parameters [e.g., delay, process variation, temperature, static stress (duty cycle), dynamic (switching activity) as well aging-relevant (e.g., fan-out, endpoint...

Currently, due to the increasing importance of recommender systems (RSs), especially in fields social networking and e-commerce, these represent one most interesting subjects computer programming. Although many research reports have previously been published this subject area, because lack clarity regarding their algorithms or limited comparisons with literature, them are difficult extend for similar applications future. Therefore, present study, we attempted improve two novel RS evaluation...

This paper considers downlink multi-user transmission facilitated by a reconfigurable intelligent surface (RIS). First, focusing on the multi-group multicast beamforming scenario, we develop fast and scalable algorithm for joint base station (BS) RIS optimization to minimize transmit power subject user quality-of-service (QoS) constraints. By exploring structure of this QoS problem, show that can be naturally decomposed into BS problem an passive max-min-fair (MMF) problem. We propose...
