Yes. The basic implementation is where the Multiple in SIMD is just 1 where
all operations are simply scalar. That suffices to meet the requirements of the
header.
If the DSP in question has vector instructions and the compiler vendor wants
to or needs to support them, the size of a byte is irrelevant.
