Smart cache is a shared cache, which is dynamically allocated to each processor 4 based on the workload. it improves the performance. it comes with they have size then the lower version of cache memory. it is also known as level 3 cache memory. to explain something more you can take an example that if a processor has 4 course then there will be only one cache memory as smart cache, and all the four processes can use that cache memory as per their need.
