Factors shifting plus stateful [M]FM token recognition out of the MFMDiskController.

Given the proliferation of MFM-related classes, establishes a subdirectory for them.

Introduces a track to segment decoder.
...
This will be needed to make formats like G64 and HFE writeable, but probably also will be usable to speed up static analysis.

Introduces a new class hierarchy for disk images.
...
Increasing independence of format-specific stuff and generic caching without mangling them into a common namespace, and allowing in some cases for a decrease in read/write blocking.

Attempts better to hide C1540 implementation details from the reader.
...
In this case not from the compiler, as it's desireable to keep `run_for` as a non-virtual call, and therefore everything else comes alone for the ride.

Deconstitutes the 6522 into component parts, templated and non-templated.

Adjusts the Oric, Vic-20 and C-1540 accordingly, albeit with the quickest possible solutions.

Refactors the Z80 to separate out interface and implementation.
...
Following the pattern just established by the 6502, puts all implementation specifics beyond the visibility of a human reading Z80.hpp and in subfolders so as to promote the idea that they shouldn't go out of their way.
2017-09-01 20:50:24 -04:00

Removes from 6502.hpp all remaining implementation details, making it purely an interface document.
...
Though those details remain visible to files including 6502.hpp through necessity.

4af333d5ec
Tidies the 6502 template and folder hierarchy.
...
Specifically: there's now just the one .h file at the top level, giving a clear indication of what a user should read. That separates implementation from interface. It also devolves a lot more to the base class because doing so makes debug builds less of a hassle. The all-RAM 6502 has been shuffled off into a subfolder, to indicate that it's not something you necessarily need know about. Also general documentation improvements have been applied: incorrect citing of the recurring-template pattern has been removed and the meaning of the two BusHandler methods has now accrued at the bus handler.

Arranges for the ZX80/81 to get a peek at target configuration prior to construction. I'm as yet undecided on whether to make this the norm.

Sketched out a protocol designed to save processing time on anything that may sleep — probably just disk controllers for now but one can easily imagine it being applicable to printers, and possibly sound chips with suitable changes in guarantee for sound packet receivers.

Consequential to the 6502 change, severs the Atari 2600's cartridge container from its former attempt at runtime polymorphism, in favour of each cartridge's specific hardware being defined as a 'bus extender'.

Introduced a test within the disk controller so as not to request illegal tracks from disks, instead automatically substituting an 'unformatted' track. Which is just empty.

Upped C++ standard to C++14 and added an #if that's intended to use the built-in std::gcd when compiled on C++17 or better. Fixed for new signedness warnings resulting for taking the step to C++14.

Started working on a CPC-oriented analyser; for now I just want to be able to make a good guess at the appropriate file to load from a disk. As it turns out, the CPC simply adopts the CP/M format, so a generic parser is appropriate. This is its beginning.

Strung up an empty shell that eventually should contain the 8272, and added appropriate IO decoding to the Amstrad.

Added an empty husk to begin support for Amstrad CPC disk image formats.

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.

Breaking its typer for now, adapted the ZX80/81 to having a Z80, not being one.

I guess it might end up living somewhere else, but introduced a header with the compiler-specific stuff to allow me to force things inline.

It's barely an implementation of the 8255, but ensured that data is bounced into the PortHandler, conveniently assuming the interaction mode used by the CPC.

Formally transferred ownership of PIO accesses to an incoming template, and decided to start being explicit about how to specify the interfaces and provide fallbacks for optional behaviour for the new, clean generation of interfaces. A full-project sweep will inevitably occur but I'll try to tie off this branch first.

Removed implementation file; this is only ever going to be a template.

Created a 6845 class and started pushing data at it and clocking it. It doesn't currently have the concept of a bus but will do, hence the in-header implementation.

Performed sufficient wiring to get to the point where attempting to load a CDT creates an instance of the Amstrad CPC and then fails only because the thing vends a nullptr CRT.

Added to the static analyser the most basic through-path for Amstrad CPC content.

Merge branch 'master' into Memptr

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
1ba3f262a2
Sketched out a template for clock-receiving components to allow them to be implemented in terms of either half or whole cycles.
2017-07-22 21:46:50 -04:00
Thomas Harte

Added Objective-C through wiring and a Swift test class for Memptr modifications. So far with a single test, that fails.

Factored out from the UEF implementation the concept of being a tape that has a queue of pending pulses and manages that queue.

Thomas Harte
238348c885
Performed the initial wiring to announce that this application supports TZX files and to route them to the ZX80/81 static analyser. The TZX class itself does not yet do much beyond basic validation. I think it'll be easiest if it follows in UEF's footsteps in queuing up pulses ahead of time, so some factoring out is now required.
2017-07-16 21:33:11 -04:00
Thomas Harte
368bff1a82
Added a shell class that will one day be able to parse CSW files, plus the logic and metadata to instantiate it when a CSW presents itself.
2017-07-10 21:43:58 -04:00
Thomas Harte

Added basic Typer support for the ZX80 and '81.

Added controls for controlling the tape motor of the ZX80/81, assuming I can find an automatic option.
