TL;DR: In this article, a memory system and method includes a cache having a filtered portion and an unfiltered portion, where the filtered portion is divided into sub-block sized components.
Abstract: A memory system and method includes a cache having a filtered portion and an unfiltered portion. The unfiltered portion is divided into block sized components, and the filtered portion is divided into sub-block sized components. Blocks evicted from the unfiltered portion have selected sub-blocks thereof cached in the filtered portion for servicing requests.

TL;DR: In this paper, a multi-level prediction algorithm is proposed, where branch predictions beyond the first level of prediction are maintained at a secondary level because the prior level was unsuccessful to highly predict the direction of the stated branch accurately.
Abstract: Disclosed is a method and apparatus providing the ability to create a multi-level prediction algorithm, whereby branch predictions beyond the first level of prediction are maintained at a secondary level because the prior level was unsuccessfully able to highly predict the direction of the stated branch accurately. A secondary level is smaller in size than the upper level through selected filtering thereby enabling high prediction accuracy of branches while minimizing the amount of hardware required to perform stated predictions.
