ARM unveiled the new Cortex-M55 core and its first NPU in this class, the Ethos-U55. Unlike the high-powered Cortex-A cores (which are used in smartphones), the M-series is used in smart speakers, cameras, wearables and various Internet of Things devices. The focus of the two new products is machine learning (ML). The M55 is the first to support the ARM Helium vector processing tech - that's a set of SIMD instructions (think SSE, AVX, etc.). This means that the core itself is 5x faster in DSP applications (e.g. Dolby Atmos processing) and 15x faster on machine learning tasks. This...
