From 7b054efa0be8dbc209c351610fd8152b4de89f99 Mon Sep 17 00:00:00 2001 From: Andree Buschmann Date: Mon, 16 May 2011 21:47:13 +0000 Subject: FS#12117: Use more IRAM for atrac3. Speeds up decoding from 1-2% (PP5022, PP5024, S5L870x) to 11% (MCF5250). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29892 a1c6a512-1295-4272-9138-f99709370657 --- apps/codecs/atrac3_rm.c | 6 ++--- apps/codecs/libatrac/atrac3.c | 11 ++++----- apps/codecs/libatrac/atrac3.h | 11 +++++---- apps/codecs/libatrac/atrac3data.h | 47 +++++++++++++++++++++------------------ 4 files changed, 41 insertions(+), 34 deletions(-) (limited to 'apps') diff --git a/apps/codecs/atrac3_rm.c b/apps/codecs/atrac3_rm.c index 4c619898bb..b666dd4513 100644 --- a/apps/codecs/atrac3_rm.c +++ b/apps/codecs/atrac3_rm.c @@ -28,9 +28,9 @@ CODEC_HEADER -static RMContext rmctx;
