Member Function Documentation

virtual void openmsx::CPU::disasmCommand	(	const std::vector< TclObject > &	tokens,
		TclObject &	result
	)		const

pure virtual

Implemented in openmsx::CPUCore< CPU_POLICY >, openmsx::CPUCore< openmsx::R800TYPE >, and openmsx::CPUCore< openmsx::Z80TYPE >.

Referenced by openmsx::MSXCPU::disasmCommand().

virtual void openmsx::CPU::execute ( bool fastForward)

pure virtual

TODO.

Implemented in openmsx::CPUCore< CPU_POLICY >, openmsx::CPUCore< openmsx::R800TYPE >, and openmsx::CPUCore< openmsx::Z80TYPE >.

virtual void openmsx::CPU::exitCPULoopAsync ( )

pure virtual

Similar to exitCPULoopSync(), but this method may be called from any thread.

Although now the loop will only be exited 'soon'.

Implemented in openmsx::CPUCore< CPU_POLICY >, openmsx::CPUCore< openmsx::R800TYPE >, and openmsx::CPUCore< openmsx::Z80TYPE >.

Referenced by openmsx::MSXCPU::exitCPULoopAsync().

virtual void openmsx::CPU::exitCPULoopSync ( )

pure virtual

Request to exit the main CPU emulation loop.

This method may only be called from the main thread. The CPU loop will immediately be exited (current instruction will be finished, but no new instruction will be executed).

Implemented in openmsx::CPUCore< CPU_POLICY >, openmsx::CPUCore< openmsx::R800TYPE >, and openmsx::CPUCore< openmsx::Z80TYPE >.

Referenced by openmsx::MSXCPU::exitCPULoopSync(), and setPaused().

virtual EmuTime::param openmsx::CPU::getCurrentTime ( ) const

pure virtual

Returns the CPU its current time.

Implemented in openmsx::CPUCore< CPU_POLICY >, openmsx::CPUCore< openmsx::R800TYPE >, and openmsx::CPUCore< openmsx::Z80TYPE >.
