Member Function Documentation
◆ getReadCacheLine()
Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.
If it is, a pointer to a buffer containing this interval must be returned. If not, a null pointer must be returned. Cacheable for reading means the data may be read directly from the buffer, thus bypassing the readMem() 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::MSXDevice.

◆ getWriteCacheLine()
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.
