Member Function Documentation

◆ getWriteCacheLine()

byte * openmsx::PanasonicRam::getWriteCacheLine ( word  start) const
overridevirtual

Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for writing.

If it is, a pointer to a buffer containing this interval must be returned. If not, a null pointer must be returned. Cacheable for writing means the data may be written directly to the buffer, thus bypassing the writeMem() method, and thus also ignoring EmuTime. The default implementation always returns a null pointer. The start of the interval is CacheLine::SIZE aligned.

Reimplemented from openmsx::MSXMemoryMapper.

◆ serialize()

template<typename Archive >
void openmsx::PanasonicRam::serialize ( Archive &  ar,
unsigned  version 
)

Definition at line 34 of file PanasonicRam.cc.

◆ writeMem()

void openmsx::PanasonicRam::writeMem ( word  address,
byte  value,
EmuTime::param  time 
)
overridevirtual

Write a given byte to a given location at a certain time to this device.

The default implementation ignores the write (does nothing).
