Hi,
- the struggle with the board took a lot of time
- continued to investigate special loads/stores
- looked for benchmarks:
EEMBC Consumer filters rgbcmy and rgbyiq should be vectorizable
once vld3, vst3/4 are supported
EEMBC Telecom viterbi is supposed to give 4x on NEON once
vectorized (according to
http://www.jp.arm.com/event/pdf/forum2007/t1-5.pdf slide 29). My old
version of viterbi is not vectorizable because of if-conversion
problems. I'd be really happy to check the new version (it is supposed
to be slightly different).
Looking into other EEMBC benchmarks.
FFMPEG http://www.ffmpeg.org/ (got this from Rony Nandy from
User Platforms). It contains hand-vectorized code for NEON.
Investigating.
I am probably taking a day off on Sunday.
Ira
