48<H2>Description</H2>
49<P>Searches through memory in the CPU for the specified data.</P>
50<P><CODE>MI_CpuFind8()</CODE> selects the most efficient memory access based on the source address to search, and appropriately searches through the memory for the specified data in 16-bit or 32-bit units. The alignment of the source address to search does not need to be considered.</P>
51<P><CODE>MI_CpuFind16()</CODE> searches through the memory for the specified data in 16-bit units. The source address to search must be 2-byte aligned.</P>
52<P><CODE>MI_CpuFind32()</CODE> searches through the memory for the specified data in 32-bit units. The source address to search must be 4-byte aligned.</P>
53
54<h2>Internal Operation</h2>
55<P>Processing is done by the CPU only and does not use the DMA controller. It does not use a system call. <CODE>MI_CpuFind8</CODE> also performs reads in units of 16/32 bits, so accessing VRAM directly will not cause problems.</P>
