1.2.1. Discussion: Overview of the DSP Circuit Board
o Discussion o The Accessories Section o The DSP and its Peripherals Section
1.2.2. Procedure: Overview of the DSP Circuit Board
In this section, you will begin to familiarize yourself with some of the components
and circuit blocks found on the digital signal processor circuit board.
 1. Locate, on the digital signal processor circuit board, all the common terminals. With
the power OFF and using an ohmmeter, verify if the common terminals are
connected together. Are all the common terminals connected together?:
a................................................................................................................yes
b................................................................................................................no Choose Answer: a
 2. Turn the power supply ON to power the circuit board.
 3. Using a dc voltmeter, measure the voltage range at the output of the dc source circuit
block. To do so, vary the potentiometer of the dc source from its smallest to its
largest values. What is the minimum voltage and maximum voiltage: Vmin(V)=-0.8 Vmax(V)=0.9
 4. Connect a microphone to the input of the microphone pre-amplifier and connect the
output of the pre-amplifier to the input of the audio amplifier. Note: “You can also
use earphones if you are in an area where an audio output from the speaker is not desirable.
 5. While talking into the microphone, familiarize yourself with the use of the
potentiometers of the microphone pre-amplifier and of the audio amplifier blocks.
 6. Remove all the connections (leads) present on the circuit board
Familiarization with the Circuit Board Using a DSP Program
In this section, you will familiarize yourself with the development environment and
you will load and run a program on the DSP.
 7. Connect the DSP board to your computer using USB port number 2 on the board
and a standard USB port on your computer. Make sure that the circuit board power
source is turned ON and that the Code Composer software is installed as explained
in Appendix C. Launch Code Composer on your computer.
 8. Make exercise_1_1 the active project simply by clicking on that project in the
Project Explorer window. Launch the Debug mode by clicking the icon to load
the program into the DSP. Next, press the icon in the menu where the debug
icon was in order to run the program. At this point, you should see the following
information on the LCD of the DSP circuit board: LabVolt 91031 Ex1-1 Echo Generator.
 9. Perform the connections shown.
 10.Adjust the DIP switch of the I/O interface so that every bit is in the 0 position. Press the
interrupt button so that the LCD displays an Echo Delay 0ms.
 11.Using the microphone, input a signal (your voice) into the DSP. Adjust the GAIN
potentiometers of the pre-amplifier and of the audio amplifier to obtain a good
quality of sound at the output. Experiment with the potentiometers. Note that a
series of black rectangles light up on the last line of the LCD as you talk into the
microphone. The length of that line corresponds to the magnitude of the input
signal from the microphone pre-amplifier. The program you downloaded into the
DSP takes the input from the CODEC (which you connected to the microphone
pre-amplifier), displays its amplitude on the LCD, and processes the signal which
is then sent to the output of the CODEC (connected to the speaker/headphones).
 12.Adjust the DIP switch such that the 8-bit number sent to the DSP corresponds to
15 (or 0000 1111_b, that is, 0000 111 in binary). Set the switches
corresponding to a one (1) to the I position. Press the interrupt button so that
the LCD displays an Echo Delay 15ms. Notice the effect of the signal processing on the sound of your voice.
 13.Repeat the last step with the following DIP switch values: 031 (0001 1111) 063 (0011 1111) 127 (0111 1111) 255 (1111 1111)
The echo effect should be quite obvious. The echo delay corresponds to the time
(in milliseconds) between consecutive echoes.
What is the minimal time required for your brain to perceive distinct repetitions?
a................................................................................................................Ty pically 5 to 15 ms
b................................................................................................................Ty pically 20 to 80 ms

 7. While keeping an eye on the main.c, Disassembly and Variables tabs, experiment
with the different debugger step arrows to observe what happens with the debugger and the different variables.  8. Press the run button
to run the program on the board. Adjust the GAIN

e frequency can go from about 10 Hz to 5027 Hz ± 5%. Choose Answer: c  11.Click on the
icon to halt the execution of code.
 12.A crucial part of debugging is to be able to know the value of a given variable at a
given moment in the process. This can be done in most cases using the Expressions
or Variables tabs. Here is a case where this method is not as convenient:
In the main.c file of Exercise 1-2, a table is declared on line 22 like this: Int16 sintbl[2048];
This means that sintbl is a table containing 2048 elements which are all 16-bit integers.
On lines 47 to 51 of the main.c file, a loop calculates a value for each of the
elements of the sintbl variable: // fill sin table for (i=0; i<2048;i++) {
sintbl[i]=sin (i/2048.0 * 2.0 *3.14159265) * 32767; }
Open the Expressions tab and type sintbl in the field to obtain the values of
the sintbl table of integers. It is necessary to expand the display to see an element of
interest. Note the address of the sintbl variable: 0x86
 13.Another method is to open a Memory window to visualize the data table. Go to the
View menu of Code Composer and choose Memory Browser to open a new window.
sintbl variable = recall(hex1)
Search for the address of the sintbl variable in the Memory window. Specify that
the looked-after variable is in the DATA part of the memory and that its type is 16-bit signed integer.
The content of the memory can thus be observed in a table such as this:
This is an improvement, but due to the sheer size of the sintbl integer table, a
different method should be used.
 14.Another method to visualize a large array of data is to use the graphics display tool.
 15.In the Tools menu, choose Graph, then Single Time. In the dialog box, set the
parameters as shown and click OK. The Start Address is the location in memory
where the table begins. The sintbl variable contains that address.
Which of the following best represents the resulting graph of the contents of the sintbl table?
a................................................................................................................
b................................................................................................................ Choose Answer: a
 16.The use of breakpoints is very important to any debug process. With the debug
process halted, insert a breakpoint in the main function below the comment
identified as “ //Breakpoint #01 ” in the code. Do so by double clicking to the left
of the line number below the Breakpoint #01 identifier in the code. In the
expressions tab, keep an eye on the value of the freq variable.
Press the run button to run the program. The execution of the program should
halt pretty quickly at the appropriate line in the main function. Note the value of the freq variable: 2531.25
Adjust the dc source potentiometer in any direction and press the run button
again. The process should run briefly until it halts again at the same line of code.
Observed freq variable = recall(fib1)
Is the current value of the freq variable the same or close to the same as observed in the previous step?
a................................................................................................................Ye s
b................................................................................................................No Choose Answer: a
Press the yellow step into arrow to execute the current line.
What is the value of the freq variable now?
a. The value remained the same
b................................................................................................................Th
e value updated corresponding to the new position of the dc source potentiometer
c................................................................................................................Th e value has dropped to zero
d................................................................................................................No ne of the above Choose Answer: b
 17.It is possible to go deeper in the code by placing a breakpoint in the assembly code directly.
The breakpoint which was placed below the “ //Breakpoint #01 ” identifier in the
C code corresponds to a breakpoint automatically placed in the disassembly code at address 0x023059.
Add a breakpoint in the Disassembly window at address 0x023086.
This adds a corresponding breakpoint in the main.c file at which line? 70
Breakpoint line = recall(fib2)
Remove the breakpoint at address 0x023086, then add a breakpoint in the main.c
file at the line you just wrote down.
At which address in the Disassembly window is a breakpoint added?
a................................................................................................................0x 023086
b................................................................................................................0x 023049
c................................................................................................................0x 023059
d................................................................................................................0x 02307C Choose Answer:d
Was the instruction at address 0x023046 the beginning of the corresponding instruction in C? a. Yes
b................................................................................................................No Choose Answer:b Why?
a. Instruction 0x023086 was an intermediate step of the command, not its beginning (0x02307C).
b................................................................................................................Th
e instruction at address 0x023046 was an include statement.
c................................................................................................................Th
e instruction at address 0x023046 was a comment only. Choose Answer:a
Remove all breakpoints inserted so far
Editing Memory and Registers
 18.Open the interrupt.c program file. Place a breakpoint after the “ //Breakpoint #02 “
identifier. Observe that the index variable is modified by this line of code. Open
the Expressions tab and add the index variable to the list of variables of interest.
It is possible to edit the value of the index variable from the Expressions tab. Click
on the Value field and change the value of the variable.
 19.It is also possible to edit the registers of the DSP. Open the Registers tab and locate
the XAR1 register in the Core Registers. Click on the value field and edit the value
of the register (in hexadecimal).
Remove the breakpoint and run the debugger again by pressing the run button .
The program should be running properly.
 20.Halt the program again (
) and edit the PC register in the Registers tab (Core
Registers) to this value: 0x023129.
Run the program again ( ) Does it perform as intended?
a................................................................................................................Ye s
b................................................................................................................No Choose Answer:b
 21.Click on the icon to terminate the execution of the program. Return to the
projects tab and quit Code Composer.
 22.Turn OFF the power supply and remove the connections (leads) you made on the circuit board.
