Flash and RAM size and processing time simulation. (a) Flash size (Mbyte) and RAM size (Kbyte) consumed during microcontroller execution for varying input image sizes (128 × 128, 160 × 160, 192 × 192, and 224 × 224 pixels, indicated by colors) and different width multipliers (0.25, 0.50, and 1.00, indicated by the number next to the point on the polyline) of MobileNet ver. 1. This data, reflecting the resource consumptions, is a recalculation in our environment, referencing the content described in the following URL (https://github.com/EEESlab/mobilenet_v1_stm32_cmsis_nn). (b) Processing time (Y-axis) for running MobileNet ver. 1 on the STM32H7 microcontroller at its maximum clock speed of 480 MHz under the conditions of input image size (128 × 128, 160 × 160, 192 × 192, and 224 × 224 pixels, indicated by colors) and width multiplier (x-axis) compatible with the STM32H7 microcontroller.
