Chapter 3
APU Software Platform
Introduction
This chapter describes the application processing unit (APU) Linux software platform, which
is further subdivided into a middleware layer, an operating system (OS) layer, and an
application stack (see Figure 3-1). The two layers are examined in conjunction because they
interact closely for most Linux subsystems. These layers are further grouped by vertical
domains which reflect the organization of this chapter:
•Video
•Audio
•Display
•Graphics
• Accelerator
•PCIe
