Detailed Explanation of NEON Instructions Optimization
The third season of ARM64 Architecture and Programming has updated its 28th lesson. This time, Uncle Ben will introduce the usage and optimization of NEON instructions.
In some scenarios, NEON instructions can achieve performance improvements of over 10 times, such as in matrix operations, image processing, and artificial intelligence. This lesson will use a 4×4 matrix multiplication as an example to let everyone experience the thrill of more than 10 times improvement.
NEON is widely used in open-source software optimization, such as ffmpeg and pixman. Learning NEON instruction optimization is very necessary.
