BLKD

dma1, {ind} [, next ARP]

√

Block Move From Data Memory to Data Memory

Move a block of words from one location in data

memory to another location in data memory. Modify the

current AR and ARP as specified. RPT or RPTK must

be used with BLKD, in the indirect addressing mode,

if more than one word is to be moved. The number of

words to be moved is 1 greater than the number

contained in RPTC at the beginning of the instruction.

BLKP

pma, dma

BLKP

pma, {ind} [, next ARP]

√

Block Move From Program Memory to Data

Memory

Move a block of words from a location in program

memory to a location in data memory. Modify the

current AR and ARP as specified. RPT or RPTK must

be used with BLKD, in the indirect addressing mode,

if more than one word is to be moved. The number of

words to be moved is 1 greater than the number

contained in RPTC at the beginning of the instruction.

√

Block Move From Program Memory to Data

Memory

Copy a block of program memory into data memory.

The block of program memory is pointed to by

src, and

the destination block of data memory is pointed to by

dst.

TMS320C20x devices: The word of the source space

can be pointed to with a long immediate value. You can

use the RPT instruction with BLPD to move

consecutive words that are pointed at indirectly in data

memory to a contiguous program-memory space.

TMS320C5x devices: The word of the source space

can be pointed to with a long immediate value or the

contents of the BMAR. You can use the RPT instruction

with BLPD to move consecutive words that are pointed

at indirectly in data memory to a contiguous

program-memory space.

BLZ

pma

BLZ

pma [, {ind} [, next ARP]]

√

Branch if Accumulator < Zero

If the contents of the accumulator are < 0, branch to the

specified program-memory address.

TMS320C2x devices: Modify the current AR and ARP

as specified.

TMS320C20x and TMS320C5x devices: Modify the

current AR and ARP as specified when the –p porting

switch is used.

† BLDD and BLPD are TMS320C5x and TMS320C20x instructions for the BLKD and BLKP instructions in the TMS320C2x and

TMS320C1 devices. The assembler converts TMS320C2x code to BLKB and BLKP.
