Abstract :
A multi-core SoC for multi-application (recognition, inference, measurement, control, and security) is developed. The configurable heterogeneous architecture with 9 CPUs and 2 matrix processors reduced 45% power consumption. The performance-oriented multi-bank matrix processor with 2-read-1-write calculation and background I/O operation is adopted. The 1 GHz CPU is realized by the delay management network applied for any kinds of applications and process technologies.
