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.
