* cache-entry struct * default values (cache size, associativity, ...)
information (and some more for better runtime performance) This is way cleaner than declaring all necessary variables for every cache and allows us to write more general algorithms.
Also started preparations for LRU replacement strategy
cache misses the number of sets in the cache was reset
instead This way the function is more general so that it can also be used for cache writes.
into caches; use paddr instead of vaddr in fill_cache_block()
Since this field was always used indicating the size of a set, the name was adapted accordingly.
* only flush blocks that were actually valid
* reset dirty flag after flushing
* flush to the correct paddr
We do not allocate less memory in the cache block struct, because we forgot to allocate more memory when we introduced the dirty flag.
Since do_sd() is used to emulate a SD instruction, it should produce only one memory access and thus at most one cash hit. load_virtual_memory() could result in a hit, or a miss, but store_virtual_memory() would definitely result in a cache hit. This increases the number of potential cache hits to two, which is not the intended behavior.
…f for example '-m'
the cache is turned on
, since the cache is always in a flushed state during the system calls.
load/store_virtual_memory() The L1-cache is now only accessed in the emulation of instruction fetches, loads, and stores.
cache-profiler reset function
"data-cache" when printing cache statistic This also fixes the alignment in the output.
…cache() and store_in_cache() respectively
declaration of get_new_timestamp()
the common code into handle_cache_miss() As a side-effect the function signatures of cache_lookup() and handle_cache_miss() have been changed by passing the paddr instead of the tag.
