UPTRA: An Ultra-Parameterized Temporal CGRA Modeling and Optimization
Yuan Dai, Yunhui Qiu, Qilong Zhu, Jingyuan Li, Wenbo Yin, Lingli Wang · 2023
Temporal Coarse-Grained Reconfigurable Architecture (CGRA) is a typical category of CGRA that supports single-cycle context switching and time-multiplexing hardware resources to perform both spatial and temporal computations. Compared with the spatial CGRA, it can be used in area and power budget-constrained scenarios, with the sacrifice of the throughput. Therefore, achieving minimum Initialization Interval (II) for higher throughput is the main objective in many works for temporal CGRA mapping.
