摘要
基于ARM Cortex A53处理器平台,对NEON协处理器的指令和编程优化方法等技术进行了分析,并以此平台进行了D2C(Depth to Color)算法的优化实现。在树莓派3B+SDK开发板上进行了充分实验,测试结果表明,NEON/VFP协处理器在保持高的算法精度的同时可以较好地提高D2C算法的运算效率,并且保持低功耗、低成本。
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.
