Initial Design and Evaluation of Riken CGRA: Data-Driven Architecture for Future HPC Initial Design and Evaluation of Riken CGRA: Data-Driven Architecture for Future HPC Boma, Adhi Carlos, Cortes Yiyu, Tan Takuya, Kojima Artur, Podabas Kentaro, Sano Boma, Adhi Carlos, Cortes Yiyu, Tan Takuya, Kojima Artur, Podabas Kentaro, Sano HPC We require different processor architectures from the present mainstream of many-core CPU architecture to further scale the computing performance at an acceptable power efficiency in the forthcoming Post-Moore era. The Coarse-Grained Reconfigurable Array (CGRA) is a promising architecture to overcome scaling limitations of the current many-core architecture, especially for spatially expanded data-flow graphs of operations that can be fully pipelined, be locally controlled, and benefit from specialization for target problems with efficient data movement. This report introduces our research project on CGRA for future HPC, from its concept, initial design, toolchain, and preliminary verification to the performance evaluation results with RTL simulation.
