This function uses the CPU to copy memory.
MI_CpuCopy8() selects the most efficient copy method based on the transfer source address and
transfer destination address, and appropriately carries out the copy in 16-bit
and 32-bit units. The alignment of the transfer source address and transfer
destination address do not need to be considered. MI_CpuCopy16()
copies in 16-bit units. Both the transfer source address and the transfer
destination address must be 2-byte aligned. MI_CpuCopy32() copies in 32-bit
units. Both the transfer source address and the transfer destination address
must be 4-byte aligned. MI_CpuCopyFast() copies at high
speed in 32-bit units. Both the transfer source address and the transfer
destination address must be 4-byte aligned.
This processes only with the CPU and does not use the DMA controller. It does not use a system call.
