Abstract(in English) | Object detection and image recognition using a Convolutional Neural Network (CNN) are used in em- bedded systems, which require reasonable price and power performance. Since CNN has high accuracy and large computation, real-time processing cannot be realized in CPU, and power consumption is too large in GPU. The CNN realization of the FPGA is low power consumption, however large on-chip memory is required and expensive. Typically, feature-map size in layers is large. This is a bottleneck in FPGA memory resource restrictions. We propose Feature-Map Separable Convolution, which 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. From experiments, we accomplished that the accuracy does not decrease so much with reducing buffer memory by 85%. |
