ee71be0e7e
Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.
2017-08-21 21:56:42 -04:00
Thomas Harte
f68565a33f
Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine.

bbb17acf3a
Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.
2017-08-03 11:50:50 -04:00
Thomas Harte
ad3a98387f
Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.
2017-08-03 11:42:31 -04:00
Thomas Harte
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
968d2bb8ba
Brought Typer into the new run_for orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.
2017-07-27 21:53:45 -04:00
Thomas Harte
9ef232157b
Revoked the operator bool() on WrappedInt as providing an indirect means for implicit but incorrect assignment to unwrapped ints. Got explicit about run_for intention and simplified HalfClockReceiver slightly by building a lossy and a flushing conversion to Cycles into HalfCycles. Adapted the all-RAM Z80 properly to return HalfCycles.
2017-07-27 21:38:50 -04:00
Thomas Harte
8361756dc4
Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.

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
a1e9a54765
Eliminated redundant uses of ClockReceiver and sought to ensure that proper run_fors are inherited all the way down.

Thomas Harte
8d1dacd951
Clean ups along the Electron::Tape line: ensured that the ClockReceiver is opted into only once, and that its run_for propagates all the way along the chain.

Thomas Harte
40339a12e1
Formalised the use of a cycles count with a divider, bringing a few additional plain-int users into the fold.

1d3ae31755
Abstracted the concept of an Acorn shifter away from being a PLLParser. The Acorn tape parser now skips using that class and uses the shifter. The actual Electron also uses the shifter. So the two are completely aligned. Net result: the Electron should successfully load exactly when static analysis was successful.

Thomas Harte

Oh yuck, it looks like I've repeated this same test in two different places. Must figure out where to factor it out to. But in the meantime, the emulated Electron has just loaded its first CSW.

Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.

Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.

Resolved spurious static analyser issue; screen mode will always be 0–6 but it doesn't know that. Setting a non-zero divider doesn't feel worth worrying about for a cleaner compile.
