A.3 Instruction Set Comparison Table

Syntax

2xx

Description

ABS

√

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

dma [, shift]

ADD {

ind} [, shift [, next ARP]]

ADD #

lk [, shift2]

√

Add to Accumulator With Shift

TMS320C1x and TMS320C2x devices: Add the

contents of the addressed data-memory location to the

accumulator; 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.

TMS320C20x and TMS320C5x devices: Add the

contents of the addressed data-memory location or an

immediate 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.

ADDB

√

Add ACCB to Accumulator

Add the contents of the ACCB to the accumulator.

ADDC

dma

ADDC {

ind} [, next ARP]

√

Add to Accumulator With Carry

Add the contents of the addressed data-memory

location and the carry bit to the accumulator.

ADDH

dma

ADDH {

ind} [, next ARP]

√

Add High to Accumulator

Add the contents of the addressed data-memory

location 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,

TMS320C20x,

and

TMS320C5x

devices: If the result of the addition generates a carry

from the accumulator’s MSB, the carry bit is set to 1.
