laboratory assignments

General report and project code submission guidelines (pdf).

lab 1: familiarization with ccs and the dsk plus audio level display

Assignment (pdf) and grade sheet. Project code and report due by 3:00pm on 05-Nov-2008.

Here is good vectors.asm file for part 3 of the assignment. Note that this file has the directive ".sect .vectors" at the top. You should make sure your linker command file has an appropriate section called ".vectors" in the correct memory location from addresses 0x00000000-0x0000021F. You may also want to edit this file if your ISR is not called "serialPortRcvISR".

lab 2: real-time floating-point filtering

Assignment (pdf) and grade sheet. Project code and report due by 3:00pm on 12-Nov-2009.

lab 3: real-time fixed-point filtering

Assignment (pdf) and grade sheet. Project code and report due by 3:00pm on 19-Nov-2009.

lab 4: hand-optimized assembly language programming

Assignment (pdf) and grade sheet. Project code and report due by 3:00pm on 03-Dec-2009.

Here is an example project that has all four versions of the single-precision floating-point dot product described in Chapter 5 of the Programmer's Guide. Careful study of the optimization tricks used in each successive dot product function should be helpful towards optimizing your code in the Laboratory 4 assignment.

lab 5: the fast fourier transform

Assignment (pdf) and grade sheet. Project code and report due by 3:00pm on 10-Dec-2009.

Here is an example project that shows how to correctly use TI's optimized FFT code. Careful study of this example project should be helpful in the Laboratory 5 assignment.

lab 6: adaptive filtering

Assignment (pdf) and grade sheet. Useful files for testing your code: lab6part1_2009.zip (three unknown systems to identify) and lab6part2_2009.zip (noise cancellation). Project code and report due by 3:00pm on 17-Dec-2009. Due to grading constraints, no late submissions can be accepted.
