sh: fix endianess and optimise the SH4 memcpy 2009-12-14T16:03:34+00:00 Giuseppe Cavallaro peppe.cavallaro@st.com 2009-12-14T15:45:49+00:00 8cd420c223f1a39c01835189669928ea8df9d221 This patch fixes the big-endian code and adds a new optimization only for little endian mode. This optimization is based on prefetching and 64bit data transfer via FPU. Tests shows that ---------------------------------------- Memory bandwidth | Gain | sh4-300 | sh4-200 ---------------------------------------- 512 bytes to 16KiB | ~20% | ~25% from 32KiB to 16MiB | ~190% | ~5% ---------------------------------------- Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
