Hi Diede,
For the Host PC, the system requirements can be found for every MATLAB release here. Note that these are minimal requirements, and that a more powerful Host PC (e.g., with more RAM or a faster CPU) would lead to better performance, especially with respect to instrumentation.
For the target machine, any of the plaforms offered by Speedgoat would work with Simulink Real-Time. To discuss your requirements in greater detail, please reach out to the Speedgoat team.
I hope this is helpful!
Dimitri
