Absolute Value of Accumulator

If the contents of the accumulator are less than zero,
replace the contents with the 2s complement of the
contents. If the contents are

≥

0, the accumulator is not

affected.

ADCB

√

Add ACCB to Accumulator With Carry

Add the contents of the ACCB and the value of the
carry bit to the accumulator. If the result of the addition
generates a carry from the accumulator’s MSB, the
carry bit is set to 1.

Add to Accumulator With Shift

TMS320C1x and TMS320C2x devices: Add the con-
tents of the addressed data-memory location to the ac-
cumulator; if a shift is specified, left shift the contents
of the location before the add. During shifting, low-
order bits are zero filled, and high-order bits are sign
extended.

TMS320C2xx and TMS320C5x devices: Add the con-
tents of the addressed data-memory location or an im-
mediate value to the accumulator; if a shift is specified,
left shift the data before the add. During shifting, low-
order bits are zero filled, and high-order bits are sign
extended if SXM = 1.

Add High to Accumulator

Add the contents of the addressed data-memory loca-
tion to the 16 MSBs of the accumulator. The LSBs are
not affected. If the result of the addition generates a
carry, the carry bit is set to 1.

TMS320C2x, TMS320C2xx, and TMS320C5x de-
vices: If the result of the addition generates a carry
from the accumulator’s MSB, the carry bit is set to 1.
