Question

Explaination of snooping protocol along with write invalidation and write update

Answer 1

Snooping protocol ensures memory cache coherency in symmetric multiprocessing (SMP) systems. Each processor cache on a bus monitors, or snoops, the bus to verify whether it has a copy of a requested data block. Before a processor writes data, other processor cache copies must be invalidated or updated. Snooping protocol is also known as bus-snooping protocol.

Answer 2

hola there,


Also referred to as a bus snooping protocol a protocol for maintaining cache coherency in symmetric multiprocessing environments In asnooping system all caches on the bus monitor the bus to determine if they have a copy of the block of data that is requested on the bus
