| Περίληψη: | The TVM–versatile tensor accelerator (VTA) stack combines hardware–software co‐design with operator‐level optimizations but relies on ARM processors for auxiliary functions like ReLU and upSample, causing data‐transfer bottlenecks and inefficiencies. To address this, we propose fusion VTA (FVTA), integrating ReLU and upSample into the RTL‐based Store module with a newly designed instruction set and lightweight C++ runtime. This ensures seamless compatibility with existing VTA modules and eliminates ARM dependence. Evaluated on YOLOv3 with a Xilinx ZCU104 board, FVTA achieves a 195 ms frame processing time for 256 × 256 RGB images—4% faster than EVTA. This work highlights how combining the flexible TVM–VTA stack with optimized circuit‐level design can significantly enhance inference efficiency. [ABSTRACT FROM AUTHOR] |
