Network configuration processor
The network configuration processor, an 16 bit transputer the IMS T222, is
used to route configuration data on the IMS B008. With reference to figure 4,
network configuration data is received on link 1, known as ConfigUp of the
IMS T222 (referred to as the T2 for brevity) either from a TRAM in slot
0 or from another board’s network configuration processor if the board is
in a pipeline of boards. This pipeline of network configuration processors
is made in a similar way to a pipeline of TRAMS on multiple boards. The
link ConfigDown on the first board in the configuration pipeline connects to
ConfigUp on the next board and so on down the pipeline (see figure 7).
Software running on the T2 examines the configuration data for connections
to be made by the IMS C004 to which the T2 has a link connection. This
connection data is extracted from the configuration data and the connections
made by sending a set of messages to the IMS C004 via link 3 of the T2.
Configuration data for the boards further down the configuration pipeline
is then sent out on link 2 (ConfigDown).
This pipeline arrangement of T2 processors is used on all INMOS mother-
