* Revise the PCM callback system after adding multichannel audio.Michael Sevakis2012-03-03
| | | | | | | | | | | | | | | | | | Additional status callback is added to pcm_play/rec_data instead of using a special function to set it. Status includes DMA error reporting to the status callback. Playback and recording callback become more alike except playback uses "const void **addr" (because the data should not be altered) and recording uses "void **addr". "const" is put in place throughout where appropriate. Most changes are fairly trivial. One that should be checked in particular because it isn't so much is telechips, if anyone cares to bother. PP5002 is not so trivial either but that tested as working.

* Sound improvements for rockboy - players now sync the sound (The gigabeat ↵Karl Kurbjun2007-06-24
| | | | | | now plays at a steady 60 fps as long as the frameskip is set properly). If a new sample is not available a blank buffer is used. All devices use 44.1 kHz for gameboy sound now so no more high pitched sounds. Added a screen rotation option. Removed unscaled code for devices with a screensize smaller than the gameboy. All buttons are now configurable. Scroll wheel devices still have button configuration problems though. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13698 a1c6a512-1295-4272-9138-f99709370657

* Major Rockboy update. Tom Ross2007-02-06
| | | | | | | | | | | | | | | | | | | | | 1) Adapt Rockboy to smaller screens (H10, X5, and iPod Nano). 2) Add the ability to use a preset palette on color targets. Choose 'Set Palette' from the main menu. 3) Clean up the code to remove any unused code and variables. 4) Changed tabs to spaces. 5) Disable reading and writing sound when sound is disabled. 6) Disbable writing to the RTC since it is not implemented yet. 7) Minor optimizations from WAC gnuboy CE and iBoy. 8) Massive clean up of code to make it appear consistent. 9) Change all C++ style comments to C style. 10) Completely reorganize dynarec. Add fixmes to all unimplemented opcodes. Add debug writes for all opcodes. Attempt to implement a few opcodes myself. 11) Silence some warnings when built using dynarec. 12) Minor reshuffling of IRAM, may or not offer a speed increase. 13) Include fixes found in the short-lived gnuboy CVS. All in all, there's about a 10% improvement on my test roms when sound is disabled and slight improvement with sound. Especially noticable when there are few sprites on screen and less action is occurring. See FS #6567. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12216 a1c6a512-1295-4272-9138-f99709370657
* Rework PCM bufferBrandon Low2006-02-07
| | | | | | | | | | | | | | | * Linked list instead of static array buffer pointers * Variable sized chunks * Improved mix handling * Reduction in duplicated code * Reduced IRAM usage w/o sacrificing performance * Converted to almost entirely unsigned math * Add pause function to reduce pcm_* exposure to playback. This WILL break playback on the iPod until linuxstb makes a followup commit. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8612 a1c6a512-1295-4272-9138-f99709370657
* Karl Kurbjun's patch #1407719:Daniel Stenberg2006-01-20
| | | | | | | | | | | | | | Here's another patch for rockboy that adds automatic frameskip (it's pretty rough as I haven't figured out an accurate timer), fullscreen support on the H300, and a bit of assembly and some IRAM stuff. I'm not sure if I'm doing the IRAM stuff correct though as it doesn't seem to make much of a difference if any. I've also added a statistics option that will show how many frames per second the gameboy is seeing (not what the player is getting) and what the frameskip is at. When you enable stats sometimes you have to go back into the menu and then come out to clear erronous values. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8397 a1c6a512-1295-4272-9138-f99709370657
