2 SOFTWARE ARCHITECTURE

This section describes the software architecture of the S/UNI-4x622 device driver. This includes a

discussion of the driver’s external interfaces and its main components.

2.1 Driver External Interfaces

Figure 1 illustrates the external interfaces defined for the S/UNI-4x622 device driver.

Application Programming Interface

The driver Application Programming Interface (API) is a list of high-level functions that can be

invoked by application programmers to configure, control and monitor S/UNI-4x622 devices.

The API functions perform operations that are more meaningful from a system’s perspective. The

API includes functions such as:

RTOS

Function Calls Application Callbacks

Hardware

Interrupts

Service Callbacks

Application

S/UNI-4x622 Device Driver

S/UNI-4x622 Devices

Service Calls

Register
