Asynchronous memory access chaining

Babak Falsafi, Yusuf Onur Koçberber, Boris Robert Grot

In-memory databases rely on pointer-intensive data structures to quickly locate data in memory. A single lookup operation in such data structures often exhibits long-latency memory stalls due to dependent pointer dereferences. Hiding the memory latency by ...

Dark Silicon Accelerators for Database Indexing

Babak Falsafi, Yusuf Onur Koçberber, Kevin Lim

The growing explosion of digital data motivates renewed emphasis on new architectures for future data-centric workloads. At the same time, the inability of power to scale with increasing transistor counts has led to a recent focus on “dark silicon” designs ...
