Method Details

[hide private]

init(self)
(Constructor)

source code

Hand in a register definition which consists of a list of (<name>, <width>) tuples.

Overrides: memory.IMemory.__init__

undefFlags(self)

source code

Used in PDE. A flag setting operation has resulted in un-defined value. Set the flags to un-defined as well.

readMemValue(self, addr, size)

source code

Overrides: memory.IMemory.readMemValue

executeOpcode(self, op)

source code

This is the core method for the

Overrides: Emulator.executeOpcode: (inherited documentation)

getRegister(self, index, mode=None)

source code

Return the current value of the specified register index.

Overrides: registers.RegisterContext.getRegister

setRegister(self, index, value, mode=None)

source code

Set a register value by index.

Overrides: registers.RegisterContext.setRegister

integerSubtraction(self, op)

source code

Do the core of integer subtraction but only *return* the resulting value rather than assigning it. (allows cmp and sub to use the same code)
