Brief

Running inference tasks at the edge of the sensing infrastructure minimizes the user's network bandwidth and improves the response time. When envisioning battery-powered IoT devices with smart capabilities, the limited energy budget puts constraints on the design of computing platforms for edge computing. Microcontroller Units (MCUs), which dominate the low-power spectrum of the computing platforms, typically feature limited memory resources (up to few MB of FLASH and below 1 MB of on-chip RAM) and lack floating-point hardware support. Hence, the deployment of high computational and memory requirements of deep learning workloads on edge devices results exceptionally challenging.

Low-precision integer arithmetic is a necessary ingredient for enabling Deep Learning inference on tiny and resource-constrained IoT edge devices. The approach described by Rusci et al. leveraged heterogeneous mixed-precision to deploy deep inference networks on tiny MCUs. The proposed technique aims at cutting the number of bits of individual weight or activation tensors below 8 bits up to fit the memory constraints and, at the same time, paying a limited accuracy drop if compared to the full-precision network. However, despite the numerous works addressing quantization on the server-side, no solution is provided for the deployment phase, especially if considering the mixed-precision sub-byte scenario. To tackle this problem, we present CMix-NN, an open-source mixed-precision library for quantized neural networks deployment on microcontroller targets. Differently, from state-of-the-art deployment solutions available for MCUs, our library supports convolutional kernels with any bit precision* in the set of 8, 4 and 2 bits, for any of the convolution operands.
