EXP. NO. : 8 STUDY OF ADDRESSING MODES OF DSP

DATE :

AIM:

To study about direct, indirect and immediate addressing modes in TMS320C50 debugger.

TOOLS REQUIRED:

1. System with TMS 320C50 debugger software2. TMS 320C50 Kit.

ALGORITHM:

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.4. Store the accumulator content in specified address location.

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.

PROCEDURE:

Open ME Debugger for C50. Create a new project and new assembly file. Type the program Save and add the program to the project Add the command file to the project and build the project Load the program to kit through serial port Run the program and verify the output through communication window

EXP. NO. : 12 IMPLEMENTATION OF FIR FILTER

DATE :

AIM:

To design a FIR low pass, high pass, band pass and band reject filters in serial mode.

TOOLS REQUIRED:

1. System with TMS 320C50 debugger software2. TMS 320C50 Kit.3. CRO

ALGORITHM:

1. Start the program.2. Initialize the C table value.3. Load the auxillary register with 0200H.4. Modify the auxillary register zero.5. Block the C table to the program.6. Set configuration control bit.7. Load the data pointer with 0AH.8. Initialize the analog to digital conversion.9. Load the auxillary register 1 with 0300 content.10. Load the accumulator in 8000H.11. AND the accumulator with 0FFFH.12. Subtract the accumulator content with data 800H.13. Modify the auxillary register 1.14. Store the accumulator data in 8000H.15. Load the auxillary register 1 with content 0333H.16. Zero the accumulator register.17. Multiply the accumulator with data.18. Load the program register, with PM bits to accumulator.19. Load the auxillary register 1 with content 0300H.20. Add accumulator content with 800H.21. Shift the accumulator right 1 bit.22. Store the accumulator content in 8200 location.23. Branch the program to step 7.

PROCEDURE:

Open ME Debugger for C50. Create a new project and new assembly file. Type the program Save and add the program to the project Add the command file to the project and build the project Load the program to kit through serial port Run the program and verify the output using CRO
