| Abstract(in English) | Object detection and image recognition using a convolutional neural network (CNN) are used in embedded systems. Embedded systems require reasonable price and power performance. CNN has high accuracy and large computation. In realizing CNN, real-time processing cannot be realized in CPUs, and power consumption is too large in GPUs. The CNN realization of the FPGA is low power consumption, but large on-chip memory are required. Large memory FPGAs are expensive. Feature-map size output in convolution layers is large. This is a bottleneck in FPGA memory resource restrictions. We propose Feature-Map Separable Convolution. This makes an inference with divided feature-map. The feature-map size becomes smaller when an input image size becomes smaller. Thus, the buffer memory can be reduced. By experiments, we accomplished that the accuracy of CNN does not change so much with making buffer memory to 70%. |
