What are the main issues associated with multiprocessor
caches and how might you solve them?
Answer Posted / narendra
issue : Cache coherency or Data coherency. The problem is
all the processors cache should have exactly the same
shared data (cohenrent data). and there are races possible
with multiprocessors.
possible solution: use one central cache controller which
will get all the read/write requests from all the
processors and peripherals so that it can make sure there
are no races and cache coherency is maintained.

Calculate rise delay of a 3-input NAND gate driving a 3-input NOR gate through a 6mm long and 0.45m wide metal wire with sheet resistance R = 0.065 / and Cpermicron= 0.25 fF/m. The resistance and capacitance of the unit NMOS are 6.5k and 2.5fF. Use a 3 segment -model for the wire. Consider PMOS and NMOS size of reference inverter as 2 and 1 respectively. Use appropriate sizing for the NAND and NOR gate.
