Synchronous Bus Protocol
Introduction to Computer Architecture
1. What happens if the addressed device does not respond due to a malfunction during a read operation? What problems would this cause and what remedies are possible?
2. How is the synchronous timing diagram affected as distance between the processor and the I/O device increases
3. The synchronous bus protocol specifies that the slave device should send its data only in the second phase of the clock. It is possible that some device may recognize its address and is ready to send data sooner. Why is it not allowed to do so? Would the processor receive wrong data? Would any other problem arise?
4. An industrial plan uses several sensors to monitor temperature, pressure, and other factors. Each sensor incudes a switch that moves to the ON position when the corresponding parameter exceeds a preset limit.
Eight such sensors need to be connected to the bus of a 16-bit computer Design an appropriate interface to enable the state of all eight switches to be read simultaneously as a single byte. Assume the bus is synchronous and that it uses the timing sequence discussed.
