متن کاملReducing DRAM Latencies with an Integrated Memory Hierarchy Design
In this paper, we address the severe performance gap caused by high processor clock rates and slow DRAM accesses. We show that even with an aggressive, next-generation memory system using four Direct Rambus channels and an integrated one-megabyte level-two cache, a processor still spends over half of its time stalling for L2 misses. Large cache blocks can improve performance, but only when coup...
متن کاملDetecting subject-specific activations using fuzzy clustering
Inter-subject variability in evoked brain responses is attracting attention because it may reflect important variability in structure-function relationships over subjects. This variability could be a signature of degenerate (many-to-one) structure-function mappings in normal subjects or reflect changes that are disclosed by brain damage. In this paper, we describe a non-iterative fuzzy clusteri...
متن کاملReducing DRAM Access Latency by Exploiting DRAM Leakage Characteristics and Common Access Patterns
DRAM-based memory is a critical factor that creates a bottleneck on the system performance since the processor speed largely outperforms the DRAM latency. In this thesis, we develop a low-cost mechanism, called ChargeCache, which enables faster access to recently-accessed rows in DRAM, with no modifications to DRAM chips. Our mechanism is based on the key observation that a recently-accessed ro...
متن کاملReducing On-Chip DRAM Energy via Data Transfer Size Optimization
This paper proposes a software-controllable variable linesize (SC-VLS) cache architecture for low power embedded systems. High bandwidth between logic and a DRAM is realized by means of advanced integrated technology. System-in-Silicon is one of the architectural frameworks to realize the high bandwidth. An ASIC and a specific SRAM are mounted onto a silicon interposer. Each chip is connected t...
