TMS320C1x/C2x/C20x/C5x Instruction Set Comparison

Syntax

Description

2xx

SHM

√

Set Hold Mode

Set the HM status bit to 1.

SMMR

dma, #lk

SMMR {

ind}, #lk [, next ARP]

√

Store Memory-Mapped Register

Store the memory-mapped register value, pointed at

by the 7 LSBs of the data-memory address, into the

long immediate addressed data-memory location. The

9 MSBs of the data-memory address of the

memory-mapped register are cleared, regardless of

the current value of DP or the upper 9 bits of AR(ARP).

SOVM

√

Set Overflow Mode

Set the OVM status bit to 1; this enables overflow

mode. (The ROVM instruction clears OVM.)

SPAC

√

Subtract P Register From Accumulator

Subtract the contents of the P register from the

contents of the accumulator.

TMS320C2x,

TMS320C20x,

and

TMS320C5x

devices: Before the subtraction, shift the contents of

the P register as specified by the PM status bits.

SPH

dma

SPH {

ind} [, next ARP]

√

Store High P Register

Store the high-order bits of the P register (shifted as

specified by the PM status bits) at the addressed

data-memory location.

SPL

dma

SPL {

ind} [, next ARP]

√

Store Low P Register

Store the low-order bits of the P register (shifted as

specified by the PM status bits) at the addressed

data-memory location.

SPLK #

lk, dma

SPLK #

lk, {ind} [, next ARP]

√

Store Parallel Long Immediate

Write a full 16-bit pattern into a memory location. The

parallel logic unit (PLU) supports this bit manipulation

independently of the ALU, so the accumulator is

unaffected.

SPM

2-bit constant

√

Set P Register Output Shift Mode

Copy a 2-bit immediate value into the PM field of ST1.

This controls shifting of the P register as shown below:

PM = 002 Multiplier output is not shifted.

PM = 012 Multiplier output is left shifted one place

and zero filled.

PM = 102 Multiplier output is left shifted four places

and zero filled.

PM = 112 Multiplier output is right shifted six places

and sign extended; the LSBs are lost.
