ZYNQ中的双核处理器Cortex-A9中使用的Neon协处理器,先了解一下neon,引用ARM的原文,
The ARM® NEON™ general-purpose SIMD engine efficiently processes current and future multimedia formats, enhancing the user experience.
NEON technology can accelerate multimedia and signal processing algorithms such as video encode/decode, 2D/3D graphics, gaming, audio and speech processing, image processing, telephony, and sound synthesis by at least 3x the performance of ARMv5 and at least 2x the performance of ARMv6 SIMD. http://www.arm.com/products/processors/technologies/neon.php
NEON利用SIMD(single Instruction,Multiple Data)结构,即单指令多数据的方式,看来就是将串行处理的方式改为并行处理,引用原图,
