Documentation

data BusState Source #

Interface for the CPU that allows it to read/write to RAM

Constructors

Fields

_cpuVram :: !MemoryPointer
Pointer to writeable memory
_cartridge :: !Rom
Read-only memory, see Rom
_controller :: !ControllerState
Aka Joypad
_cycles :: !Integer
_unsleptCycles :: !Int
The number of cycles that we need to call threadDelay for
_cycleCallback :: Double -> Int -> IO (Double, Int)
The function to call threadDelay according to unsleptCycles (> unsleptCyclesThreshold) The return value is the new number of unslept cycles
_lastSleepTime :: !Double
_ppuState :: !PPUState
The state of the PPU
_ppuPointers :: !PPUPointers
Memory dedicated to PPU
_onNewFrame :: BusState -> IO ()
_pollControls :: ControllerState -> IO ControllerState
_dataBus :: !Byte
Last read/written byte
_apuState :: !APUState
_cpuInterrupt :: !InterruptStatus
