If you write code that does some math, but the actual math is implemented in external libraries. Many machine learning developers fall into this category, for the same reason they’re OK using Python and similar high-level but slow languages for their job. Some C++ folks are happy with vect...

Arm SIMD Best Practices: Optimize your code for mobile, laptops, IoT, and embedded devices. Boost performance for cloud and edge development.
Neon intrinsics是一组编译器用来替代Neon 指令的的内建函数，该内建函数风格跟C/C++函数一致，方便普通...
But for developers who need to squeeze every bit of performance out of their applications, that's not enough. Since the dawn of computing, performance-minded programmers have used insights about hardware to fine tune their code. Let's say you're working on code for which speed is paramount,...
(Boolean extremum solution algorithm of NumPy) is used to describe the process of optimizing the algorithm using NEON and some key techniques. Compared with the C code optimization using a compiler, the performance is improved by about 80%. The following content is very helpful for developers ...

Libraries written in C/C++ enable developers to write SIMD-hardware-oblivious application code and create code for specific SIMD extensions with little overhead. The separation into SIMD-hardware-oblivious code and a SIMD abstraction library reduces complexity and makes it ...
An AOS approach is less efficient for two reasons: 1) not all SIMD computation slots may be utilized (i.e., the w vertex component may not be needed); 2) horizontal reduction operations (i.e., dot products such as a * x + b * y + c * z) are typically needed, which use ...
