Attempt to build fixed operations into type.
...
This simplifies callees and should make all helper functions automatically able to optimise themselves for fixed operations.

Shift operation stuff into its own namespace, making data_select_active a free function.

5c7f94d2ef
Introduce the possibility of operation type as a template parameter.
...
It's already proven possible to provide this for instruction fetch, so I think it'll immediately be a win. But more importantly it opens a path forwards for further improvement.

Implements ROM::Request::validate.
...
It now also validates ROM sizes, so can no longer take a const Map.
2021-06-04 18:54:50 -04:00
Thomas Harte
a30eeaab6a
Starts to introduce a new grammar for ROM requests.
...
They can be optional, and chained together in AND or OR combinations. A central catalogue knows the definitions of all ROMs.
2021-06-03 21:55:59 -04:00
Thomas Harte
d77ddaf4fa
Switches the Electron to JustInTimeActor video.
...
Also reorders template parameters; I think that specifying a different time base is likely to be more common than using a divider.

Splits 'CRTMachine' into three parts: ScanProducer, AudioProducer, TimedMachine.
...
Simultaneously cleans up some of the naming conventions and tries to make things a bit more template-compatible.

Thomas Harte
394ee61c78
Starts a switch to reflectable-style runtime options.
...
The Amstrad CPC and ZX80/81 have made the jump so far, subject to caveats. The macOS build is unlikely currently to work properly.

On further reflection, I think events should occur after the running period.
...
I'm testing this now for sanity in 2/4bpp mode.

Towards ST 1bpp support: puts vsync in an appropriate location, starts experimenting with proper CRT timings.

Thomas Harte
294e09f275
All these 'override's can be 'final's.
...
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.
2020-01-23 22:57:51 -05:00
Thomas Harte
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.
2020-01-21 22:28:25 -05:00
Thomas Harte
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 latching video interrupts until acknowledged.

Seems to fix Cisco Heat, at least. I have no idea whether I'm latching the correct thing, whether IACK should clear both or only one, etc.
