Memory organization and data layout for instruction set extensions with architecturally visible storage
2009
Proceedings of the 2009 International Conference on Computer-Aided Design - ICCAD '09
Preserved Fulltext
Present application specific embedded systems tend to choose instruction set extensions (ISEs) based on limitations imposed by the available data bandwidth to custom functional units (CFUs). ...
In this paper we propose a novel methodology for laying out data in memories, generating highbandwidth memory systems by making use of existing lowbandwidth low-cost ones and designing custom functional ...
EXTENSIONS AND FUTURE WORK One potential area for future work is to generate memories and data layouts for a set of ISEs with conflicting access patterns that operate on the same data. ...
