We present Vega, an IoT end-node SoC capable of scaling from a 1.7 μW fully retentive cognitive sleep mode up to 32.2 GOPS (@ 49.4 mW) peak performance on NSAAs, including mobile DNN inference, exploiting  ...  1.6 MB of state-retentive SRAM, and 4 MB of non-volatile MRAM.  ...  CONCLUSION We presented Vega, an always-on IoT end-node SoC featuring a 1.7 µW fully retentive cognitive wake-up unit coupled with a power/performance/precision scalable SoC.  ...
