Tutorial: 30 March 1998

1. How are parameters transferred between functions in a microprocessor system. Assume that the software has been written in a high-level language.

   What differences might there be when

   • a RISC processor is used,
   • a PMMU is in operation?

2. What are the main reasons for using the following devices and techniques in multi-processor systems?
   • the VME bus,
   • co-processors,
   • transputers.

3. In the VME bus, describe the sequence of operations which takes place when one processor card seeks to access memory on another card.
