13 Common Interface Module – CIM-SB600

13.1 CIM-SB600 Architecture

CIM-SB600 employs a modular component design with an open interface definition such that the

amount of functional components included, the sequence these components are called, and the

way these components are called could all be different, depend on different requirements of

different OEM projects/platforms.

CIM-SB600 requires bios code base provides addresses (for ex. SMBUS Base Address).

SB600-CIM can be divided into four functional sub modules:

• Power On Reset initialization (SBPOR)

• POST initialization.

• RUNTIME initialization.

• SMM Module

The following diagram is a conceptual overview of the AMD SB600-CIM infrastructure and its

functional modules in relative with a typical system BIOS power on boot up timeframe. Each

modular component (functional module) will be introduced in more detail in later chapters.
