The NEON coprocessor instructions and programming optimization method based on ARM Cortex-A53 platform are introduced in this paper,and the optimization of D2C is also discussed.The D2C(Depth to Color) implementation is fully tested in Raspberry Pi 3B+ SDK board,and the results show NEON/VFP coprocessors improve the D2C calculation efficiency and keep good algorithm accuracy and low power and low cost.
