In recent years, the demand for memory performance has grown rapidly due to the increasing number of cores on a single CPU, along with the integration of graphics processing units and other accelerators. Caching has been a very effective way to relieve bandwidth demand and to reduce average memory latency. As shown by the cache feature table in Fig. 23.9.1, there is a big latency gap between SRAM...
As energy efficiency has become a primary concern, system designers have greater need for a flexible and highly accurate power estimation method for evaluating different architecture options. Since memory is an increasingly dominant power consumer, we reexamine existing memory power models and propose a highly efficient microcomponent-based approach with data-aware refinement for accurate system-level...
Presented is a novel half Gb DRAM device for 3D stacked systems utilizing TSV. It is designed through the use of a new computer-aided design methodology and which realizes 819 Gb/s bandwidth across 16 channels and <10ns read latency on a 45nm DRAM process. The architecture is based on small subarrays with short WL and BL to realize the low latency and energy efficiency. We also integrated several...
In this paper, a full realization of the higher order method of moments (HMoM) with a parallel out-of-core LU solver on GPU/CPU platform is presented in detail, mainly including three parts: In the first part, both global-auxiliary table and local-auxiliary table are introduced for reducing a lot of tedious and repetitive calculations, and then a realization for GPU-oriented programming is proposed...
