rockbox/firmware/export/dsp-util.h, branch master My Rockbox tree Add rbcodecplatform.h and rbcodecconfig.h. 2012-05-03T12:49:35+00:00 Sean Bartell wingedtachikoma@gmail.com 2011-10-30T16:05:04+00:00 cadb3627fcc32cec3a97183c0a1462fe0ff04755 librbcodec users must provide these two files when the library is built. rbcodecconfig.h provides configuration #defines and basic types, and will be included by public librbcodec headers, so it must not conflict with the user's code. rbcodecplatform.h provides various OS functions, and will only be included by source files and private headers. This system is intended to provide maximum flexibility for use on embedded systems, where no operating system headers are included. Unix systems can just copy rbcodecconfig-example.h and rbcodecplatform-unix.h with minimal changes.

Add a more correct absolute difference function to dsp-util. 2012-04-26T20:04:43+00:00 Michael Sevakis jethead71@rockbox.org 2012-04-26T19:21:43+00:00 e5c3327cefb4e6f3a9089ad30fd12bb8f40a0658 Differences between signed samples cover the entire unsigned 32-bit range. "abs" will think any difference exceeding INT32_MAX is negative which is not corrent. Test which argument is greater and subtract the lesser from it, outputting unsigned difference.

Collect the 16-bit signed range sample clipping routines scattered about, which can be optimized on armv6 and create firmware/export/dsp-util.h (for lack of better place right now). 2011-12-04T18:19:39+00:00 Michael Sevakis jethead71@rockbox.org 2011-12-04T18:19:39+00:00 a43df152c2adf737208bbeb294a0a13608d3cc43 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31142 a1c6a512-1295-4272-9138-f99709370657
