func (*Bus) ClearMapping ¶

func (b *Bus) ClearMapping(offset, length uint16)

func (*Bus) Length ¶

func (b *Bus) Length() uint16

func (*Bus) MapHandler ¶

func (b *Bus) MapHandler(offset uint16, length uint16, h Handler)

func (Bus) MemRead ¶

func (b Bus) MemRead(offset uint16) byte

func (Bus) MemWrite ¶

func (b Bus) MemWrite(offset uint16, val byte) byte

func (Bus) Ptr ¶

func (b Bus) Ptr() uintptr

func (Bus) String ¶

func (b Bus) String() string

func (Null) Length ¶

func (n Null) Length() uint16

func (Null) MemRead ¶

func (n Null) MemRead(offset uint16) byte

func (Null) MemWrite ¶

func (n Null) MemWrite(offset uint16, v byte) byte

func (Null) Ptr ¶

func (n Null) Ptr() uintptr

func (Null) String ¶

func (n Null) String() string

func (RAM) Length ¶

func (r RAM) Length() uint16

func (RAM) MemRead ¶

func (r RAM) MemRead(offset uint16) byte

func (RAM) MemWrite ¶

func (r RAM) MemWrite(offset uint16, val byte) byte

func (RAM) Ptr ¶

func (r RAM) Ptr() uintptr

func (RAM) Resize ¶

func (r RAM) Resize(newsize int) RAM

Resize will return a copy of RAM with the specified size. If RAM is large enough to accomodate the new size (less or equal to capacity), then the exact same memory buffer will be returned. If however it is required to grow the memory buffer, a new buffer will be allocated, and data will be copied

Reducing the size of a memory will not free memory, and re-growing it will cause data that was written there to be still there.

func (RAM) String ¶

func (r RAM) String() string

func (ROM) Length ¶

func (r ROM) Length() uint16

func (ROM) MemRead ¶

func (r ROM) MemRead(offset uint16) byte

func (ROM) MemWrite ¶

func (r ROM) MemWrite(offset uint16, val byte) byte

func (ROM) Ptr ¶

func (r ROM) Ptr() uintptr

func (ROM) String ¶

func (r ROM) String() string
