NXP claims that this support provides the industry's first compiler implementation of the Glow neural network for higher performance with low memory footprint on its i.MX RT crossover MCUs. Originally developed by Facebook, Glow is able to integrate target-specific optimizations. NXP took advantage of this ability using Glow neural network libraries for Arm Cortex-M cores and the Cadence Tensilica HiFi 4 DSP. The capability is also integrated into NXP's eIQ Machine Learning Software Development Environment, which is freely available within NXP's MCUXpresso SDK. As an NN compiler, Glow takes in an unoptimized neural network and generates highly optimized code.
