Is there a C implementation for GNU ARM NEON intrinsics?

I'm not looking for a portable SIMD implementation.

All I need is: a bit-accurate implementation. Performance doesn't matter very much as long as it's not extremely slow.

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

I'm pretty used to this development cycle when I work with TI DSP like described here . I want to carry this on when I move to ARM NEON.

Is this already done, or do I need to invent the wheel?

Solution

  • Intel has a useful set of macros, neon2sse.h which translate NEON intrinsics to SSE. This enables you to build and test your C/C++ code with NEON intrinsics on an x86 platform.
