Functions

EmuTime openmsx::VDPAccessSlots::getAccessSlot (EmuTime::param frame, EmuTime::param time, Delta delta, const VDP &vdp)
 Return the time of the next available access slot that is at least 'delta' cycles later than 'time'. More...
 
Calculator openmsx::VDPAccessSlots::getCalculator (EmuTime::param frame, EmuTime::param time, EmuTime::param limit, const VDP &vdp)
 When many calls to getAccessSlot() are needed, it's more efficient to instead use this function. More...
