I'd rather say that what happens more often is that the software (C
code + compiler) doesn't support the circular buffers, but the
hardware DOES support it. Does't the 64x have circular buffers?

Jerry: did you maybe mean that there are efficient data structures to
implement circular buffers in software if the compiler doesn't support
it directly, inferring from the underlying hardware?

Yes. There are interesting ways to use the same data laid down nore than
once, end to end, so that each pass is continuous ans checking for
wrap-around on each access isn't needed. Think about what has to be done
when the stride is greater than one!
