3.4. Set-Top-Box SOC
In Chapter 1, we showed an example of a set-top-box SOC. The block diagram for this SOC is repeated here in Figure 3.5.
Figure 3.5. A Set-Top-Box SOC
In this SOC, typical traffic flow for cable applications is as follows:
From video-processing unit to memory controller
From memory controller to video-processing unit
From I/O controller to memory controller
From memory controller to display controller
For satellite applications, the traffic flow changes to:
From Utopia interface to video-processing unit
From video-processing unit to memory controller
From memory controller to display controller
All of the above traffic goes through ...
