Multiply and Accumulate
Multiply a data-memory value by a program-memory
value and add the previous product (shifted as speci-
fied by the PM status bits) to the accumulator.

Multiply and Accumulate With Data Move
Multiply a data-memory value by a program-memory
value and add the previous product (shifted as speci-
fied by the PM status bits) to the accumulator. If the
data-memory address is in on-chip RAM block B0, B1,
or B2, copy the contents of the address to the next
higher address.
MADD

MADD {

√
√
Multiply and Accumulate With Data Move and
Dynamic Addressing
Multiply a data-memory value by a program-memory
value and add the previous product (shifted as defined
by the PM status bits) into the accumulator. The pro-
gram-memory address is contained in the BMAR; this
allows for dynamic addressing of coefficient tables.
MADD functions the same as MADS, with the addition
of data move for on-chip RAM blocks.

Multiply and Accumulate With Dynamic
Addressing

gram-memory address is contained in the BMAR; this
allows for dynamic addressing of coefficient tables.

Multiply
TMS320C1x and TMS320C2x devices: Multiply the
contents of the T register by the contents of the ad-
dressed data-memory location; place the result in the
P register.
TMS320C2xx and TMS320C5x devices: Multiply the
contents of the T register (TMS320C2xx) or TREG0
(TMS320C5x) by the contents of the addressed data-
memory location or a 13-bit or 16-bit immediate value;
place the result in the P register.
