Is there a C implementation for GNU ARM NEON intrinsics?

Question

I'm not looking for a portable SIMD implementation.

All I need is a bit-accurate implementation. Performance does not matter much if it is not very slow.

I want to use it for development and testing at an early stage so that I can compile and run on the host computer for the first 10+ iterations. Then cross-compile and fine tune performance against the ARM target.

I am quite used to this development cycle when I work with TI DSP, such as described here . I want to continue this when I move to ARM NEON.

Is it already done, or do I need to invent a wheel?

Answer 1

Intel has a useful set of macrosneon2sse.h that convert NEON-intrinsics to SSE. This allows you to create and test your C / C ++ code using the x86 built-in NEON functions.
