With increase in GPU register file (RF) size, its power consumption has also increased. Since RF exists at the highest level in cache hierarchy, designing it with memories with high write latency/energy (e.g., spin transfer torque RAM) can lead to large energy loss. In this paper, we present an spin orbit torque RAM (SOT-RAM) based RF design which provides higher energy efficiency than SRAM and STT-RAM...
The approximate computing paradigm can be leveraged to exploit the intrinsic error resilience of many applications to enable highly efficient memory implementations. Most emerging memory technologies have a wide range of performance/power/reliability trade-offs which can be exploited in fault tolerant approximate computing. In this work, we use approximate computing to tolerate the increased retention...
Developing new methods to evaluate the software reliability in an early design stage of the system can save the design costs and efforts, and will positively impact the product time-to-market. In this paper, we propose a novel fault injection technique to evaluate the reliability of a computing system running a software at early design stage where the hardware architecture is not completely defined...
