NEON intrinsics可以视作在NEON指令上面封装了一层接口。当用户在C程序中调用NEON intrinsics接口时,编译器会自动生成相关的NEON指令。NEON intrinsics可以跨Arm v7-A/v8-A运行。只要编程一次,就可以借助编译器生成相应的NEON代码。如果用户在代码中使用了Arm v8-A AArc...
NEON intrinsics可以视作在NEON指令上面封装了一层接口。当用户在C程序中调用NEON intrinsics接口时,编译器会自动生成相关的NEON指令。NEON intrinsics可以跨Arm v7-A/v8-A运行。只要编程一次,就可以借助编译器生成相应的NEON代码。如果用户在代码中使用了Arm v8-A AArch64特有的NEON指令,只要如下例所示,用宏定义(__...
This section compares the Neon-related features of both the Armv7-A and Armv8-A architectures. In addition, general purpose Arm registers and Arm instructions, which are used often for Neon programming, will also be mentioned. However, the focus is still on the Neon technology. Register Armv7...
NEON Instructions Describes the assembly programming of NEON technology. It contains the following sections: Summary of NEON instructions. Summary of shared NEON and VFP instructions. Interleaving provided by load and store element and structure instructions. ...
This series of guides introduces Neon, shows you how to optimise C code using intrinsics, and how to use your compiler to automatically generate code that contains Armv8-A advanced SIMD instructions. View the Guide SVE and SVE2 Programming Examples This guide provides an in-depth description ...
