configuration pipeline. Figure 24 shows the standard way of
achieving this: Link 1 of the module in site0 is taken via a link patch
to the T2. Note that this effectively terminates both
PipeHead and
ConfigUp .
3.3.2.4 Software for Link Configuration
To configure their network to a desired topology the user can
program the T2 pipeline directly or make use of the software system
or wiring files supplied with the board.
Note: Transtech module motherboards are currently supplied with
the NCS (network Configuration Software) for electronic link
configuration.
3.3.3 System Control
The design requirements of the motherboard, part of the TRAM
standard, stated that a hierarchical control structure be provided to
control networks of transputers. In practice this allows networks to be
constructed out of subnetworks. An example might be where each
TRAM in a
master
network controls its own subnetwork of
transputers.
In order to control a transputer, only three signals are needed: a
signal to reset the transputer, a signal to analyse (statically debug)
the transputer and a signal from the transputer to indicate that an
error has occurred. These signals are collectively called the
subsystem signals.
