a71c5946f0
Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine.
...
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.

d97a073d1b
Adds the necessary routine for all machines to be able to respond to get_scan_status.
...
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

Switches to accepting a bit mask of events to run_until.

cb61e84868
Starts building out higher-level run_until functionality.
...
Specifically: you can now run until the next set of speaker samples has been delivered.
2020-01-20 12:12:23 -05:00
Thomas Harte
8349005c4b
Adds CRTMachine::run_until, which will run until a condition is true.
...
I want to get to being able to say "run until the beam is 60% of the way down", "run until a new packet of audio has been delivered", etc.

Thomas Harte
8a699b6072
Kills setup_output definitively, saving some indirection. set_scan_target takes its place.

b40211d2c0
Starts to bend 'CRTMachine' to a world farther from owning the GPU relationship.
2018-11-03 21:54:25 -04:00
Thomas Harte
da4d883321
Adds first, incomplete attempts to talk to a ScanTarget from the CRT.
...
Does away with the hassle of `unsigned` while I'm here; that was a schoolboy error.
2018-11-03 19:58:44 -04:00
Thomas Harte
3862fdb44c
Simplifies initialisation procedure for all machines.
...
With the side effect of allowing every machine to try to load only the ROMs that it needs.

Makes get_clock_rate protected. It's now an implementation detail.
2018-03-22 10:01:18 -04:00
Thomas Harte
da3d65c18f
Devolves time to cycle conversion to machines.
...
Thereby avoids a whole bunch of complicated machinations that would otherwise have been required of the multimachine.

4e720d57b2
With debugging hooks still on display, makes first attempt at dynamic analysis.

Thomas Harte
c12aaea747
Attempts to get as far as running the MultiMachine.
...
In doing so, fixes the long-standing bug that machines that output audio but don't have a listener produce a divide by zero.

ac80d10cd8
Separates the component parts of running an audio stream: task deferral, filtering and generation.
...
Walking towards improving opportunities for composition.

Eliminates a large number of instance of end-of-line tabs.

Modifies the Vic-20 and C1540 to bring them into the realm of self-ROM fetching.
...
Hence enables Vic-20 support within kiosk mode as currently drafted.
2017-11-07 21:19:51 -05:00
Thomas Harte
0116d7f071
Added a platform-neutral route for feeding ROMs to machines, in a platform-dependant fashion; implemented for the CPC.

After a quick check, added a couple of other _delegate initialisations. I should probably find a way to template this.
2017-08-01 07:07:43 -04:00
Thomas Harte
763e3b65d1
Ensured a proper initial value for delegate_.

4abd62e62b
Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.
2017-07-27 22:05:29 -04:00
Thomas Harte
75d67ee770
Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.
2017-07-25 20:20:55 -04:00
Thomas Harte
2ff157cf7a
Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.

Added documentation.

Made yet another guess at Commodore analysis. Elevated fast tape-related unnatural speed up to the OS-side mechanisms.
2016-09-12 22:06:03 -04:00
Thomas Harte
d9016909ed
Added some wiring for PAL/NTSC mode switching on the Vic, making an attempt to simplify the whole loop of having different clock rates.
2016-08-14 13:33:20 -04:00

Eliminated plain pointer passing for object types.

Fixed best-effort updater actually to run, finally moved clock rate announcement into the C++ side of things, started working on a mechanism to allow clock rate to be updated.

Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.
