# Calculate Miss rate of L2 cache given global and L1 miss rates

If I have a Global miss rate of all caches of a total of 5.41% and the miss rate of a single level cache of 9.13%, how can I effectively calculate how much the second level cache miss rate need to be?

I found this where it says that the Local miss rate equals misses in a cache divided by the total number of memory accesses to this cache (Miss rate L2) and Global miss rate equals misses in a cache divided by the total number of memory accesses generated by the CPU (Miss Rate L1 x Miss Rate L2).

So if I divide 5.41% / 9.13% it equals 0.5926% for my second level cache. Is this assumption correct?

0.0541    = L2 misses * 0.0913
