The QoS-aware memory hierarchy So the idea behind a QoS-aware memory hierarchy is relatively straightforward (though I have oversimplified a bit here). But the devil, as always, is in the details.

No single memory sub-system is “best” in all categories, and therefore, most systems use a variety of memory solutions from different levels in the hierarchy to achieve the desired results. High-end ...

Memory Hierarchy Design – Part 3. Memory technology and optimizations, which examined innovations in main memory that offer improved system performance This installment, which examines architecture ...

Virtual memory and virtual machines, which examined architecture support for protecting processes from each other via virtual memory and the role of virtual machines This installment, which puts it ...

As a result, memory now dominates system cost. This paper argues for a paradigm shift from today’s simple memory hierarchy toward specialized memory architectures that exploit application-specific ...
