CHAPTER 4: THE ALLWINNER A20 EMBEDDED PROCESSOR

4. Introduction to the chapter

In this chapter is located the information about the heart of OLinuXino – its microcontroller. The
information is a modified version of the datasheet provided by its manufacturers.

4.1 The processor

The main feature of the A20 processor is the sheer computing power that allows FullHD video
playback. The graphical processing unit is also pretty powerful and supported by the default
software packages that come with the OlinuXino boards. The software support for the features in
the processor is at pretty good state thanks to the efforts of the community and Allwinner
themselves.
