The difference in efficiency between 32- and 8-/16-bit
systems is substantial: a generic 32-bit multiple/accumulate
requires four multiplications and four additions on a 16-bit
processor with additional overhead for data accessing. Thus,
a single 32-bit multiplication could require about 20-40
cycles on a 16-bit processor. On a 32-bit UC3C processor this
operation requires only a single cycle supported with a 32-bit
pipeline for rapid data access.

inb4, this bugger is also 16bit
