Study of Addressing Modes Using Tms320c54 Kit

STUDY OF ADDRESSING MODES USING TMS320C54 KIT

EX.NO:11

DATE:

AIM:

To study about direct, indirect and immediate addressing modes in TMS320C54 debugger

APPARATUS REQUIRED:

1. System with TMS 320C54 debugger software

2. TMS 320C54 Kit.

3. RS232 cable.

PROGRAM LOGIC:

IMMEDIATE ADDRESSING MODE:

1.  Initialize data pointer with 100H data.

2.  Load the accumulator with first data.

3.  Add the second data with accumulator content.

DIRECT ADDRESSING MODE:

1. Initialize data pointer with 100H data.

2. Load the accumulator with first data, whose address is specified in the Instruction.

3. Add the accumulator content with second data, whose address is specified in the instruction.

4. Store the accumulator content in specified address location

IN-DIRECT ADDRESSING MODE:

1. Load the auxiliary register with address location of first data.

2. The auxiliary register (AR0) is modified indirectly as # symbol.

3. Load the second data into accumulator and perform addition operation.

4. Store the result

Program for immediate addressing mode:

.MMREGS

.TEXT

START:

LDP #100H

LACC #1241H

ADD #1200H

SACL 2H

HTL: END

Program for direct addressing mode:

.MMREGS

.TEXT

START:

LDP #100H

LACC 0H

ADD 1H

SACL 2H

HTL: END

Program for adding two numbers with indirect addressing mode

.MMREGS

.TEXT

START:

LAR AR0,#8000H

MAR *,AR0

LACC *+,0 ;WITH ZERO SHIFT

ADD *+ SACL *+

HTL: END

RESULT:

Thus, the arithmetic operations using TMS320c5416x kit was performed successfully.

SAMPLING OF INPUT SIGNAL AND DISPLAY USING TMS320C5X

EX NO: 12

DATE:

AIM:

To write a program to convert analog signals into digital signals using TMS320C54 debugger

APPARATUS REQUIRED:

1. System with VI debugger software
2. TMS 320C54 Kit.

3. CR0

4. Function Generator

PROGRAM LOGIC:

1. Initialize data pointer with 100H data

2. Give the analog signal as input

3. Introduce the time delay as per required

4. Observe the discrete signal as output

PROGRAM:

MMREGS

.TEXT LDP #100H

IN 0,06H

NOP

IN 0,04H

RPT #4FFH

NOP

OUT 0,04H

RPT #4FFH

NOP

B START

RESULT:

Thus the sampling process is verified and executed using TMS320C54X.
