Gem5-X

Yasir Mahmood Qureshi, William Andrew Simon, Marina Zapater, Katzalin Olcoz, David Atienza
2021 ACM Transactions on Architecture and Code Optimization (TACO)  
In this article, we present gem5-X, a system-level simulation framework, based on gem-5, for architectural exploration of heterogeneous many-core systems.  ...  Then, using a two-step exploration methodology, we develop a new optimized clustered-heterogeneous architecture with HBM2 in gem5-X for video analytics application.  ...  partially supported by the ERC Consolidator Grant COMPUSAPIEN (GA No. 725657), the EC H2020 WiPLASH (GA No. 863337), the EC H2020 RECIPE (GA No. 801137), the Spanish CM (S2018/TCS-4423), the EU FEDER and  ...
