Description

The INIC-based MOST PC Interface provides a high-speed connection between a PC and MOST network. It allows access to packet data and control messages.

The chip set used for the MOST PC Interface consists of the an Intelligent Network Interface Controller (INIC) and a PC interface chip. Whereas the INIC is used as interface to the MOST network, the PC interface chip implements the connection to the PCI bus. This chip set, together with the corresponding device drivers, builds a complete interface solution for transferring packet data and control messages. Both 44.1 and 48 kHz system frame rates are selectable in timing master mode.

These MOST PC Interface operates in bus master mode for the highest possible data transfer at minimized system overhead for the main CPU.

MOST Device Development

MOST PCI Interfaces enable software simulation for MOST devices without the need for any additional hardware. Network devices in the development phase may be controlled with the MOST NetServices V2 or V3 (separate license required) with these MOST PC Interfaces. All of them can also be used as a “sparring partner” for Devices Under Test (DUT).

These INIC-based MOST PC Interfaces permit access to the MOST Control Message Service by providing all software necessary to develop a MOST NetServices client directly on the board. They also provide the ability to send and receive packet data using:

• MOST NetServices Layer I,
• MOST NetServices Layer I and Layer II, or
• MOST NetServices Layer I and Layer II, plus the MOST High application

which enables development of a PC-based MOST device simulation.
