Lingxin 01 is designed by Xinsheng Technology, a company born from the chip Research Institute of Zhejiang Dahua Technology Co., LTD., and manufactured by TSMC, using a 28-nanometer process.

Similar to the structure of the Tesla FSD chip, the Linxin 01 is also composed of a CPU, NN neural network processor, and video image processing unit.
< br >
NN processor belongs to the standard of self-developed AI chip. Each NN processor of the LinX01 integrates eight neural network processing cores with a combined computing power of 4.2TOPS, and Zhu Jiangming said that any number of cores can be combined on demand.

More important than NN units are the CPU and image processing units that are easier to jam.

With Dahua's accumulation in the field of visual recognition hardware, the Linxin 01 has a single image recognition capability of 16K (16384x16384) resolution (270 million pixels). Dynamic video decoding supports 12 channels of 1080P\/25fps, or 6 channels of 1080P\/50fps.

As for the CPU, zero run and core rise have chosen a name that is not loud in the field of automatic driving - Flathead brother.
< br >
As the first chip products of Alidamo Institute, the Pingtou Brother CPU debuted in 2019, divided into C910, C860, C810 and C807 four models, of which zero run selected C860.
< br >
From the perspective of hardware parameters alone, the C860 is not powerful. The core 01 uses a dual-core design of the C860, the main frequency of 1GHZ, more importantly, the C860 is a 32-bit processor.
< br >
Compared with the ARM Cortex A57 used by Nvidia Xavier and the Cortex A72 used by Tesla Hardware 3.0, the biggest disadvantage of the flat-head brother C860 is the frequency, and the 32-bit CPU cannot support more than 3.25GB of memory.
< br >
For the choice of 32-bit processors, Fang Wei explained that the C910 appeared relatively late, at that time has not been verified by customers, and the reliability of the Ling core 01 is very high.
< br >
In addition, the C910 is based on the RISC-V instruction set CPU, and there is a problem that there is no patent protection at all, and there is no method for replacement and settlement in the event of patent disputes. The C860 has fully independent, domestic intellectual property rights.
