48<H2>Description</H2>
49<P>Uses CPU to perform a memory comparison.</P>
50<P><CODE>MI_CpuComp8()</CODE> compares using 8-bit units. The alignment of the addresses to compare does not matter.</P>
51<P><CODE>MI_CpuComp16()</CODE> compares using 16-bit units. The second address to compare must be 2-byte aligned.</P>
52<P><CODE>MI_CpuComp32()</CODE> compares using 32-bit units. The second address to compare 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.
