After a prolonged battle between the HW team (cheering for Intel
Multibus II with it's superfast MPC and transport communications over
the backplane) and us (cheering for VxWorks and VMEbus for attractive
development environment possibilities), the final score was:
Multibus II 1
VxWorks/VME nil.
MB II will now form the basis for current and future realtime
developments.
The function of our system is to provide data collection via X.25
interface, format conversion, and later data transmission on ISDN using
OSI layered communications model on the B channel.
The current proposed architecture for the target is as follows:
iSBC 386/258 to control initial configuration and booting, and act as
disk server to UNIX and RMX
iSBC 386/116 running UNIX Sys V/386, to act as interface to system, and
X.25 and ISDN clients (i.e. the application)
iSBC 386/MIX developement for ISDN server
iSBC 186/410 for X.25 server
For the development system, the proposal is to use an Intel System 520
development rack, with TCP/IP interface provided by Wollongong WIN/TCP,
networked to our Sun/3 environment.
What are the possibilities for development infrastructure and tools in
such a configuration (e.g. cross compilers, remote symbolic
debugging)? Has anyone got experience in a similar environment?
Any ideas for an alternative system architecture?
Thanks in advance.
