Cache controller
The cache controller is the mind of the cache. Its responsibilities include: performing the snarfs and snoops, updating the TRAM and SRAM and implementing the write policy. Also the cache controller is responsible fordetermining if memory request is cacheable and if a request is a cache miss or hit. The cache controller detects cache misses and controls receiving andsending the cells. This device also controls interface. The cache controller have a status register, which may be read by the processor. The bits of the status register can be used to signal to the processor.
The cache controller accepts commands from the processor. Following are the examplesof the commands are
The cache controller will send a cell to request a cache line when a miss occurs. This cell can also flush an existing dirty line. It is expecting cell to be returned containing the data, and the CPU is stalled till such a cell is received.
