Instruction Set Comparison Table

A-24

Syntax

Description

2xx

MPYA

dma

MPYA {

ind} [, next ARP]

√

Multiply and Accumulate Previous Product

Multiply the contents of the T register (TMS320C2x/

2xx) or TREG0 (TMS320C5x) by the contents of the

addressed data-memory location; place the result in

the P register. Add the previous product (shifted as

specified by the PM status bits) to the accumulator.

MPYK

13-bit constant

√

Multiply Immediate

Multiply the contents of the T register (TMS320C2x/

2xx) or TREG0 (TMS320C5x) by a signed 13-bit

constant; place the result in the P register.

MPYS

dma

MPYS {

ind} [, next ARP]

√

Multiply and Subtract Previous Product

Multiply the contents of the T register (TMS320C2x/

2xx) or TREG0 (TMS320C5x) by the contents of the

addressed data-memory location; place the result in

the P register. Subtract the previous product (shifted

as specified by the PM status bits) from the

accumulator.

MPYU

dma

MPYU {

ind} [, next ARP]

√

Multiply Unsigned

Multiply the unsigned contents of the T register

(TMS320C2x/2xx) or TREG0 (TMS320C5x) by the

unsigned contents of the addressed data-memory

location; place the result in the P register.

NEG

√

Negate Accumulator

Negate

(2s

complement)

the

contents

the

accumulator.

NMI

√

Nonmaskable Interrupt

Force the program counter to the nonmaskable

interrupt vector location 24h. NMI has the same effect

as a hardware nonmaskable interrupt.

NOP

√

No Operation

Perform no operation.

NORM

NORM {

ind}

√

Normalize Contents of Accumulator

Normalize a signed number in the accumulator.

OPL [#

lk,] dma

OPL [#

lk,] {ind} [, next ARP]

√

OR With DBMR or Long Immediate

If a long immediate is specified, OR it with the value at

the specified data-memory location; otherwise, the

second operand of the OR operation is the contents of

the DBMR. The result is written back into the

data-memory location previously holding the first

operand.
