Overview
Matrox Meteor-II /1394 hardware
reference
This chapter provides information on the architecture,
operating modes, and supported features of the Matrox
Meteor-II /1394 board.
For a summary of the information given in this chapter and
detailed specifications of connectors and pinouts, refer to
Appendix B of this manual.
Matrox Meteor-II /1394 is capable of acting as bus manager
(cycle master), isochronous resource manager, and node
controller ("root"). The cycle master triggers the data signal at
125-microsecond intervals. The isochronous resource manager
is responsible for reserving, distributing, and managing the two
modes of data streams (isochronous and asynchronous) along
the available bandwidth. The root controller can control all
peripheral devices connected (up to a maximum of 62).
The 1394 bus transfers real-time (isochronous) data streams
through a four-layered architecture, two of which are
implemented in hardware: the Physical Layer and the Link
Layer.
Note that Matrox Meteor-II /1394 does not support the Matrox
Meteor-II MJPEG module.
