On ARM platform (under Android OS) I used library function clock_gettime (time.h) to get execution time, CLOCK_MONOTONIC parameter was used in function call clock_gettime to get monotonic time, I did the same mean time measurements in first case for C code and in second case for C + Neon intrinsics.

Arm Neon intrinsics technology is an advanced Single Instruction Multiple Data (SIMD) architecture extension for Arm processors. SIMD performs the same operation on a sequence, or vector, of data during a single CPU cycle. For instance, if you are summing numbers from two one-dimensional arrays, you must add them one by one.

The Neon Programmer's Guide for Armv8-A provides more information about intrinsics and Neon programming in general. Here are two introduction guides on using Neon Intrinsics with Android: Neon Intrinsics - Getting Started on Android; Neon Intrinsics - How to Truncate Thresholding and Convolution of a 1D Signal If you also check gcc arm intrinsics page, you shouldn't be able to find any pointer to those vector types. They mean to map to SIMD registers, and you don't generally talk pointers to registers. If you would like to get more information about neon programming you can check ARM's website and this blog series. do as the suggestion, use -mfloat-abi=softp or -mfloat-abi=hard the difference is about the ABI for passing floating point arguments, the inference speed should be very near Neon Intrinsics is supported by Arm Compilers, gcc and LLVM.

ARM has also defined a standard set of NEON vector types to be used with these intrinsics. Use the links below and replace the name of the intrinsic in the code with your intrinsic.

I would like to translate neon intrinsic to llvm-IR, code like this: /* neon_example.c - Neon intrinsics example program */ #include #include #include #include /* fill array with increasing integers beginning I have looked into PFFFT but it does not have any ARM NEON intrinsics in code. Actually, I have code that translates NEON intrinsics to x86 SSE using gcc-x86 compiler and custom header files instead of arm_neon.h.
