Cadence (Tensilica LX3 core) isnt exactly Chinese. What espressif did that was really smart was re-purposing design created as an SDIO WiFi chip for tablets into IoT darling, pretty much _by accident_ (someone in Shenzhen leaked SDK into english speaking website). There is a very strong unwritten rule among Chinese electronic firms of not leaking documentation outside the great wall, because that weakens their technological advantage (for example try finding documentation for one of chinese LCD scalers).
