Design and Analysis of Soft-Error ResilienceMechanisms for GPU Register File

Modern graphics processing units (GPUs) are using increasingly larger register file (RF) which occupies a large fraction of GPU core area and is very frequently accessed. This makes RF vulnerable to soft-errors (SE). In this paper, we present two techniques for improving SE resilience of GPU RF. First, we propose compressing the RF values for reducing the number of vulnerable bits. We leverage... » read more

Applications And Low Power

By Pallab Chatterjee As new process technologies are being developed to make devices smaller, they are also driving the operating power lower for the devices and systems. The goal is to reduce the power requirements for the system and hence increase the functional life on a single battery charge. This concept has worked in the semiconductor industry from 10-micron processes down to the 6... » read more
