Two examples of NEON parallel acceleration optimization
System testing and analysis 1.Principle introduction: NEON is an optimized instruction set under the ARM architecture, mainly to implement SIMD (Single Instruction Multiple Data, Single Instruction Multiple Data Stream). An instruction set that operates on multiple operands simultaneously. When dealing with some simple and highly repetitive algorithms, it can be processed in parallel, which greatly […]
