AVR32908
Many DSP functions operate on vectors. A vector is a buffer filled with fixed-point
numbers known as elements. Each vector element represents one signal sample or
filter coefficient. Vectors can have any length, but some DSP functions may require
vectors to have 2*n, 4*n, or 6*n elements. Some functions may also require
coefficient vectors to be of a fixed length.
All vectors must be stored word (32-bit) aligned in SRAM because it allows the AVR
UC3 CPU to fetch multiple elements more efficiently.
Power the EVK1104 by plugging the USB cable into on the USB connectors.
Connect a headphone or speaker to the jack in order to listen to the music.
The DSP demo is controlled by a graphical user interface (GUI) on the EVK1104
LCD. The touch sensitive buttons and wheel below the screen are used for input. The
buttons and the wheel take on different functions depending on the element selected.
When the application is reset, the menu is in idle mode and no function on the screen
is selected.

Turn the wheel and see how you can select different elements on the screen.
Observe how the instructions in the box at the lower right part of the screen
change as you select different elements.
