Chapter 6: Video Generation for Text and Image Display on T-Pad
Introduction
In this chapter, the ALU will be displayed on T-Pad with an image in the background. Terasic T-Pad
provides a touch screen, which enables us to incorporate a video component. The strong multimedia
capabilities of the T-Pad are used to develop an application that would ease the process of viewing an
image from a SD Card. SD Card is used to access the images/pictures because every Digital single-lens
reflex (DSLR) camera used in the modern day stores clicked images on it. Moreover, these images are
generally in JPEG format and hence the user can store a large quantity of images on the card.
The ALU with image at the background supports following functionalities
1. Mounting a SD Card and reading files from it.
2. Displaying pictures on the touch screen display.
3. A simple ALU on the top of the image.
4. Intuitive touch to perform various functions of the ALU.
