TMS320C1x/C2x/C20x/C5x Instruction Set Comparison

Syntax

Description

2xx

MAC

pma, dma

MAC

pma, {ind} [, next ARP]

√

Multiply and Accumulate

Multiply a data-memory value by a program-memory

value and add the previous product (shifted as

specified by the PM status bits) to the accumulator.

MACD

dma, pma

MACD

pma, {ind} [, next ARP]

√

Multiply and Accumulate With Data Move

Multiply a data-memory value by a program-memory

value and add the previous product (shifted as

specified 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

dma

MADD {

ind} [, next ARP]

√

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

program-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.

MADS

dma

MADS {

ind} [, next ARP]

√

Multiply and Accumulate With 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

program-memory address is contained in the BMAR;

this allows for dynamic addressing of coefficient

tables.

MAR

dma

MAR {

ind} [, next ARP]

√

Modify Auxiliary Register

Modify the current AR or ARP as specified. MAR acts

as NOP in indirect addressing mode.

MPY

dma

MPY {

ind} [, next ARP]

MPY #

√

Multiply

TMS320C1x and TMS320C2x devices: Multiply the

contents of the T register by the contents of the

addressed data-memory location; place the result in

the P register.

TMS320C20x and TMS320C5x devices: Multiply the

contents of the T register (TMS320C20x) 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.
