Multi-level tag controller for emulating a tagged memory using an in-memory table.
Zeroing of the in memory tag table can be disabled by building with -D NO_TAGTABLE_ZEROING.

The 4 versions of the tag controller built for the simulations discussed in the report can be found in branches of this repository:
original_latency - original single-cache
incremental_latency - improved single-cache
not_ooo_no_write_resps - simple pipelined
final_latency - out-of-order pipelined
