- TODO : check the Apple //e Bible for this ...
- Calculates 2-byte branch instructions (Bxx +OFF)--that sit right at page boundary (at 0x..fe 0x..ff)--as 3 cycles
rather than 4, since PC has already advanced to the new page (matches logic currently in x86/cpu.S
Squashed commit of the following:
REFACTOR : fix comments, logging, and rename some variables
REFACTOR : fix up some commentary, clean deadc0de
REFACTOR : mostly fix all the audio glitches
- amplitudes of samples are gradually shifted to zero when speaker has fallen silent
- simplifies speaker state machine
- fullspeed mode only enqueues quiet samples
REFACTOR : fix up a number of other functions and comments
REFACTOR : clean up code to submit normal speed wave buffer to OpenAL
Move some initializations to the cpu_thread()
REFACTOR : properly reset the speaker cycles access counter so we don't underflow and assert
REFACTOR : should never get a split buffer from our soundcore implementation
Fix warning from gcc ... static array size needs to be computed from integer values
REFACTOR : gcc (but not clang) complains about these, so just make them preprocessor defines
REFACTOR : use unsigned long long because we don't actually care that this counter is 64bit
REFACTOR : remainder_buffer and miscellaneous tweaks
- Adds implementation commentary to document remainder_buffer purpose
- Also adds sample average for square wave boundary in case where remainder_buffer not used (whole-sample boundary)
- Variable renaming and code shuffling
REFACTOR : do not dynamically alloc remainder buffer
- Never attribute to cache-coherancy bugs what is a simple thread race =P
REFACTOR : comments and whitespace
REFACTOR : rename public speaker API functions
REFACTOR : clean up public speaker API
REFACTOR : tabs to spaces
REFACTOR : moar deadc0de clean up and renaming
REFACTOR : remove deadc0de paths from soundcore
REFACTOR : fully excise soundtype stuff now that we only support soundcard output
Move a file static to function scope
REFACTOR : rename more variables and remove deadc0de
REFACTOR : samples_buffer naming and change to explict int16_t
REFACTOR : removed deadc0de and shuffled code locations
REFACTOR : remainder buffer naming and clarify type
REFACTOR : move joystick timing to VM module and remove header visibility
REFACTOR : clarify speaker variable name
REFACTOR : clarify cycle counting codepaths
REFACTOR : VBL/timing interfaces
- eliminates passing around a common global
REFACTOR : names and comments
HACK around volume issue
REFACTOR : rename speaker feedback variable
REFACTOR : rename global total cycle count
REFACTOR : rename a constant
Fix test builds
REFACTOR: rename to is_fullspeed
REFACTOR : local variable naming changes
REFACTOR : migrate cycle timing variables to correct location and remove header visibility
Allow fullspeed codepath to update speaker
REFACTOR : remove deadc0de paths in prep for cleanup
REFACTOR : speaker now manages its own VM entry point
* Apparently the I flag is not set for PLP and RTI, or rather, our implementation of
mockingboard seems to expect it not to be set for these opcodes...
