Chapter 4
tPad Demonstrations
This chapter gives detailed description of the provided bundles of exclusive demonstrations
implemented on tPad. These demonstrations are particularly designed (or ported) for tPad, with the
goal of showing the potential capabilities of the kit and showcase the unique benefits of
FPGA-based SOPC systems such as reducing BOM costs by integrating powerful graphics and
video processing circuits within the FPGA.

To run and recompile the demonstrations, you should:
Install Altera Quartus II 10.0 and NIOS II EDS 10.0 or later edition on the host computer
Install the USB-Blaster driver software. You can find instructions in the tutorial “Getting
Started with Altera‟s DE2-115 Board” (tut_initialDE2-115.pdf) which is available on the
DE2-115 system CD
Copy the entire demonstrations folder from the tPad system CD to your host computer

The tPad development kit comes preconfigured with a default utility that boots up on power on and
allows users to quickly select, load, and run different Ready-to-Run demonstrations stored on an SD
Card using the tPad touch panel. Figure 4-1 gives a snapshot of the default application selector
interface (Note*). Every demonstration consists of a FPGA hardware image and an application
software image. When you select a demonstration the application selector copies the hardware
image to EPCS device and software image to flash memory and reconfigures the FPGA with your
selection. For more comprehensive information of the application selector factory configuration,
please refer to chapter 5.
