On-Chip Memory System Optimization Design for the FT64 Scientific Stream Accelerator

Abstract

In this paper shows the extension of application domains, hardware-managed memory structures such as caches are drawing attention for dealing with irregular stream applications. However, since a real application usually has both regular and irregular stream characteristics, conventional stream register files, caches, or combinations thereof have shortcomings. This article focuses on combining software- and hardware-managed memory structures and presents a new syncretic memory system based on the ft64 stream accelerator.
