TMM and HMS Hardware Resources

Hi,

 

Would anyone be able to explain how TMM and the HMS share resources please? From a hardware point of view TMM is described as a dedicated system and HMS as a seperate subsystem but the TMM software process runs within the HMS so can I assume they share memory and CPU resources? And where the HMS is concerned, on multicore processors, I assume it uses all cores through SMP etc.?

  • Thanks nitass, I'd seen the first document at least but unfortunately neither provide the clarity I'm looking for.
  • OK, so the lowdown I got was that the HMS only runs on one CPU and has a restricted amount of system RAM assigned.

     

    TMM 'boots' and runs within HMS and would fail if the HMS fails.
