Memory Management for Dual-addressing Memory Architecture

概要

Dual-addressing memory architecture is designed for two-dimensional memory access with both row-major and column-major localities. In this paper, we highlight two memory management issues in dual-addressing memory. First, to avoid the external fragmentation, we propose a virtual dual-addressing memory design to enable memory management via operating system. After that, to deal with the size mismatch between user-defined data and dual-addressing memory, we discuss data arrangement policies at different data granularity. With the proposed memory management techniques, we are capable of maximizing the memory utilization of dual-addressing memory.
