Initial release


Purpose

I had developed 11 emulaters in these years and implemented many devices.
There are many devices that are commonly used for exmaple i8255. I can divert their souce codes but I cannot use common one source code for each devices.
Becase the device class includes the codes for the unique circuit for each machine, for example i8255 class includes the codes for the keyboard.

I have started this common source code project to settle this problem.
I also aim to convine the win32 source codes for each works.

Description

For the purpose, I implement the devices under the rule listed below:

  1. Implement the device base class. This base class has the interface method connected to the memory bus, I/O bus, and other devices.
  2. Implement the every device classes as the superclass of the device base class.
  3. Register the destination device class connected to the output port as the pointer of device base class and also register the input port id.
  4. The device base class also has the event callback method. Every devices can register their own pointer to the event manager class.
You may feel that the purpose is similar to MAME/MESS project. The difference is that the pointer of interface function is registered in MAME/MESS, but the pointer of device class is registered in my project. And I dont aim to convine to one binary like MAME/MESS.

Example 1) dma

MEMORY* memory; // this is the unique hardware
UPD765A* fdc;
I8237* dma;

dma->set_context(0, memory);
dma->set_context(1, fdc);

The device base class has the common memory bus interface write_data8(addr, data) and read_data8(addr). I8237 has MEMORY and UPD765A pointer as the device base class pointer and he can read and write their data with these interface.

Exmaple 2) keyboard with i8255

I8255* pio;
KEYBOARD* key; // this is the unique hardware

pio->set_context_port_a(key, SIG_KEYBOARD_COLUMN);
key->set_context(pio, SIG_I8255_PORT_B);

In this case, we write the key matrix column to i8255 Port A and read the key stats from i8255 Port B.
The device base class has the common input interface write_signal(id, data, mask).
When we write the column to i8255 Port A, I8255 class write the data as key->write_signal(SIG_KEYBOARD_COLUMN, data, 0xff).
In KEYBOARD class's write_signal(), create the key status for the given column and return it to i8255 Port B like pio->write_signal(SIG_I8255_PORT_B, data, 0xff).

Example 3) i8253 timer

I8253* pit;

pit->set_context_ch0(pit, SIG_I8253_CLOCK_1);
pit->set_context_ch1(pit, SIG_I8253_CLOCK_2);

In this case, OUT#0 is connected to CLK#1, and OUT#1 is connected to CLK#2.

Example 4) TMS9918 vsync event

void TMS9918::initialize() {
vm->regist_vsync_event(this);
}
void TMS9981::vsync_event(int v, int clock) {
// event manager call this function in every vsync
}
