CASSANN-v2: A high-performance CNN accelerator architecture with on-chip memory self-adaptive tuning

[摘要] This work proposes a high-performance reconfigurable CNN accelerator architecture, called CASSANN-v2, which can achieve 1TOPS peak performance at 1GHz. CASSANN-v2 provides the function of on-chip SRAM memory real-time adaptive tuning by parameter configuration to reduce the intermediate output data transmission to further exploit the acceleration performance. The system simulation results show that CASSANN-v2 exhibits excellent performance on VGG-16 and ResNet-18 inference, with a throughput of 1009.54GOPS and 923.24GOPS at 1GHz, which achieved 98.59% and 90.20% average processing element utilization, respectively. Compared with state-of-the-art accelerator works, CASSANN-v2 improves the resource utilization by 2.02× in VGG-16 and 2.35× in ResNet-18.
