the libjpeg-turbo is very sharp implement of jpeg code,
well done in using SIMD instruction by Linaro.
But, by my benchmark, that seems not implemented encode from raw
data (that is, using function jpeg_write_raw_data) in SIMD on neon:
tjCompressYUV420 is my packaging funcion, using jpeg_write_raw_data to
encode yuv420 data as jpeg.
ROUND = 100
tjCompressYUV420 cost time = 1613 ms
tjCompress2 cost time = 833 ms
my test platform is tiny210 @ 1GHz
May I ask, do anyone know if Linaro have any plan to implement those
subrountine as SIMD in recent time?
Maybe is it coming soon ? If the answer is negation, may I ask is that
more tedious to implelement than jpeg_write_scanlines so there is no
this plan in recent time?
thank your attention.
