Square and Accumulate Previous Product
Add the contents of the P register (shifted as specified
by the PM status bits) to the accumulator. Then load
the contents of the addressed data-memory location
into the T register (TMS320C2x/2xx) or TREG0
(TMS320C5x), square the value, and store the result
in the P register.

Square and Subtract Previous Product
Subtract the contents of the P register (shifted as
specified by the PM status bits) to the accumulator.
Then load the contents of the addressed data-memory
location into the T register (TMS320C2x/2xx) or
