MMOVE

This low-level command can be used to move memory blocks at high speed between addresses. There are several cases that are covered by this command. The simplest is to copy data from one or more CPU memory locations (RAM) to another CPU memory location (RAM). This can be achieved with the standard version of the command.

If you add the VIDEO keyword, you can indicate that the memory to copy from or to copy to is not in the CPU RAM but in the RAM possibly dedicated to the GPU. In this case it is called VRAM.

You cannot move overlapped area or VRAMS together.
