    Overview

    The Network Basic Input/Output System protocol is an API on top of the TCP/IP protocol, it provides a way of communication between separate computers within a local area network via the session layer.

    Using NetBIOS, an emNet application can resolve a NetBIOS name to an IP address in the local area network.

    Key features

    • Low memory footprint
    • Seamless integration with the emNet TCP/IP stack
    • Client based NetBIOS name resolution

    Requirements

    The emNet NetBIOS implementation requires the emNet TCP/IP stack.

    Resource usage

    The ROM usage depends on the compiler options, the compiler version and the used CPU. The memory requirements of the NetBIOS module presented in the tables below have been measured on an ARM7 and a Cortex-M3 system. Details about the further configuration can be found in the sections of the specific example.

    ROM Usage on an ARM7 System

    The following resource usage has been measured on an ARM7 system using IAR Embedded Workbench V6.30.6, Thumb mode, no interwork, size optimization.

    Add-onROM
    emNet NetBIOS moduleApproximately 0.8 KByte

    ROM Usage on a Cortex-M3 System

    The following resource usage has been measured on a Cortex-M3 system using IAR Embedded Workbench V6.30.6, size optimization.

    Add-onROM
    emNet NetBIOS moduleApproximately 0.7 KByte

    RAM Usage

    Add-onROM
    emNet NetBIOS moduleApproximately 26 Bytes
