MI_CpuSend*

C Specification

#include <nitro/mi.h>

void MI_CpuSend32( const void* src, volatile void* dest, u32 size );
void MI_CpuSend16( const void* src, volatile void* dest, u32 size );

Arguments

src The transfer source address.
dest The transfer destination address.
size Transfer size

Return Values

None.

Description

Uses the CPU to transfer data to the same address. The function does not change the address of the transfer destination. It increments only the transfer origin address, and repeatedly transfers contiguous region data to the same address.

MI_CpuCopy16() transfers in 16-bit units. Both the transfer source address and the transfer destination address must be 2-byte aligned.

MI_CpuCopy32() transfers in 32-bit units. Both the transfer source address and the transfer destination address must be 4-byte aligned.

Internal Operation

This processes with the CPU only and does not use the DMA controller. System calls are not used.
