Problems solved by technology

At present, the chip deployment methods of convolutional neural network mainly include: (1) The calculation method of GPU+CPU combination has become the preferred solution for machine learning. Among them, CPU is more suitable for human-computer interaction and process control due to its versatility; Compared with the CPU block, the high price and large power consumption make it difficult to be used in low-end occasions; (2) Although ASIC is the most cost-effective convolutional neural network computing chip, but also because of the long design cycle and high cost, There are also many problems with poor flexibility; (3) FPGA programmable chips have high requirements for implanting servers, programming environments, and developer capabilities, and lack general potential, making it difficult to popularize
