FUNCTIONAL DESCRIPTION
This section describes the functionality of S3C6400X system controller. It covers the clock architecture, reset
scheme, and power management modes.
HARDWARE ARCHITECTURE
Figure 3-1 shows S3C6400X block diagram. S3C6400X consists of ARM1176 processor, several media co-
processors and various peripheral IP’s. ARM1176 processor connected to several memory controllers through 64-
bit AXI-bus to meet bandwidth requirements. Media co-processors, which include MFC (Multi-Format Codec),
JPEG, Camera interface, TV encoder and etc, are divided into five power domains. The five power domain can be
controlled independently to reduce unwanted power consumption when the IP’s are not required for an application
program.
