Mapping Method Usable with Clustered Many-core Platforms for Simulink Model
2022
Journal of Information Processing
Preserved Fulltext
The proposed algorithm combines two other algorithms: one algorithm uses the core allocation of MBP and path analysis at the cluster-level and considers effects from communication contention when determining ...
MBP maps Simulink blocks to cores using various types of information such as block characteristics, C code, and multi/manycore hardware implementation. ...
The use of multi/many-core processors has consequently increased because these are effective in improving performance. ...

This paper proposes application-to-core mapping policies to improve system performance by reducing inter-application interference in the onchip network and memory controllers. ...
How applications running on a many-core system are mapped to cores largely determines the interference between these applications in critical shared resources. ...
CONCLUSION We showed that mapping applications to cores in a manner that is aware of applications' characteristics significantly improves system performance, fairness, and energy-efficiency. ...
