  1. 2acc0ac Updated our source code header to explicitly mention that we are GPL v2 or by Daniel Stenberg · 16 years ago
  2. ef1f7d3 SPC Codec: Ensure no crash occurs on load failure which could cause emulation to be run without a program loaded on dual core (DSP wasn't initialized yet). The load failures come from core buffering not having the atomic audio file fully loaded before the codec requests the buffer (it gets as many bytes as can be provided) which IMHO isn't very atomic :). Changes in thread execution order after dumping spinlocks for general use simply revealed the buffering race condition. No fix for that will be hacked into the codec itself but should be fixed in the core. Add my copyright to files I had a significant part in developing per request of Adam Gashlin. by Michael Sevakis · 17 years ago
  3. 1a41c8a SPC Codec: Run SPC emulation on COP and audio sample processing on CPU on dual-core PortalPlayer targets. by Michael Sevakis · 17 years ago
  4. af2e9cc SPC/Coldfire: Just use msac.w instead of neg.l/mac.w. It seems fine. Must've been cache aliasing. :-) by Michael Sevakis · 17 years ago
  5. 8552eff Make the SPC codec run like it used to on Coldfire before -Os crushed it. Build as a lib using the old -O option. Should not impact ARM targets. by Michael Sevakis · 17 years ago[Renamed (87%) from apps/codecs/spc/Spc_Dsp.h]
  6. bd5c0ad Cast some more to keep both 32 bit and 64 bit simulator platforms happy. by Jens Arnold · 18 years ago
  7. 411f819 Oops. That ICONST_ATTR shouldn't be on the gauss table...yet. I leave experiments in a commit by accident way too much. :P What's the deal with getting SVN to update Id or add it? Nothing seems to work. by Michael Sevakis · 18 years ago
  8. 9764e09 SPC codec on Coldfire: Urgh. There was a whole gain stage I overlooked. :P Kill another several boost points. by Michael Sevakis · 18 years ago
  9. fa9ea27 Fix a comment that sounded a bit odd. by Michael Sevakis · 18 years ago
  10. f2b6ecd SPC codec on Coldfire: Move movclrs into the light and out of the long dark shadow cast my emac latency as much as possible. Put in a faster interpolation routine (emac saves the day...again). Add comments about what's going on. by Michael Sevakis · 18 years ago
  11. c292581 SPC Codec: Fix an overflow issue in echo with left shifting by 9 that showed on some files by using mac.l instead which is ok since the little beastie seems to prefer multiplying things. Mark asm blocks volatile so gcc doesn't get any ideas that the code can be removed as happened to me once already. by Michael Sevakis · 18 years ago
  12. 46bb37a Fix a mistake in wrapping the echo buffer. by Michael Sevakis · 18 years ago
  13. d31162a SPC codec: enable echo on ColdFire CPU. Do a couple general small optimizations. Preswap some data when running DSP for big endian. by Michael Sevakis · 18 years ago
  14. 4de600b Remove dishonest spc amplification by Adam Gashlin · 18 years ago
