SOFTWARE FEATURES

7.1 User Interface API

A development kit dedicated to the platform allows access through the API to specific code sections to

allow software customization. The development kit provides source code for a packet phone application,

drivers and diagnostic software. Other stacks are delivered in the object code. A specific development en-

vironment is provided. It includes project profiling, managing, C compiler/assembler and tools as well a

source level debugger.

7.2 System Services

MAPI offers an easy interface to control the operations necessary to setup the ADSL link and monitor the

operation conditions. The software provides an optimized control sequence to insure optimum operation

of the DynaMiTe™ chip set.

MIB2: RFC 1213: Management Information Bases (MIB2) is implemented in the device.

RTOS: Implemented RTOS is Posix compliant. The user can access various parts of the software blocks

through specific APIs. Alternate RTOS are planned.

Flash Initialization. Software is stored on an external Flash. At boot-up, the stored software is downloaded

to the device. By using compilation options, software can be executed from the internal RAM (intensive

operations) or executed from the flash. Execution is optimized by the use of an intermediate cache mem-

ory.

Startup initialization: Optional software images can be selected at startup of the device.

Broad Support Program: A BSP layer is provided to allow easy porting of proprietary software on the SOC

architecture. The BSP provides a unique hardware abstraction layer model valid for the entire product line.

This approach allows reuse of the custom solfware through the entire MTC-50xxx product line(*).
