1.2.4.3

Communications Driver Software

The communications driver software includes most of the

components that perform the communication and control

tasks

between

the

Geode

SCx200

and

the

CS1301/CS1311 (see Table 1-3).

1.2.4.4

Software Development Kit

The Software Development Kit (SDK) includes the core

software components that run on the TM32A core of the

CS1301/CS1311. These are the supporting software com-

ponents that enable the execution of the codec software on

the CS1301/CS1311 (see Table 1-4).

1.2.4.5

System Software

To expand system functionality beyond media decoding,

Geode software components are included. These are stan-

dard components to be used in a non-media enabled appli-

cation to support the required functions of an Information

Appliance. In some cases, these drivers have been opti-

mized to work with the CS1301/CS1311 (see Table 1-5).
