"Zhaoxin (Shanghai Zhaoxin Semiconductor Co., Ltd. Chinese: 兆芯; pinyin: Zhàoxīn) is a fabless semiconductor company, created in 2013 as a joint venture between VIA Technologies and the Shanghai Municipal Government. The company creates x86 compatible CPUs. The term Zhào xīn means million core. The processors are created mainly for the Chinese market: the venture is an attempt to reduce the Chinese dependence on foreign technology.
The architecture of the ZX family of processors is a continuation of VIA's Centaur Technology x86-64 Isaiah design. The ZX-A and ZX-B are based on VIA Nano X2 C4350AL. The ZX-B is identical to the ZX-A, except that it is manufactured by Shanghai Huali Microelectronics Corporation (HLMC) ."
