A 228GOPS 345 mW heterogeneous many-core processor combines bottom-up and top-down attention for high accuracy. It uses analog-digital mixed-mode neuro-fuzzy inference circuits to realize robust object recognition. Weight perturbation learning and workload-aware voltage/frequency control are adopted. The 5 Ã 10 mm2 chip with 96% recognition accuracy contains 4 SIMD vector processing elements and 32 MIMD processors.
