It is not possible to determine the total number of bits required to implement a cache with the given configurations as crucial information is missing. The total number of bits required would depend on the cache size, block size, and the associativity (i.e., direct-mapped, set-associative, or fully-associative). Additionally, other factors such as tag bits, valid bits, and replacement algorithm would also play a role in determining the total number of bits required. Without these details, a precise calculation of the required bits cannot be made.
