MicroLib Cache Wrapper

This module implements a wrapper to the cache modules defined in MicroLib. For more details of MicroLib caches, refer to the MicroLib website.

This wrapper module has two different sides. The side connected to the CPU (or to a lower level cache) and the side connected to the memory (or to a higher level cache). For the purpose of this documentation we’ll consider the port on the cpu side inCPU and outCPU as port connected to a cpu, and the port on the memory side inMEM and outMEM as memory ports as shown on the figure below.

The wrapper module also includes some MicroLib ports (in green) to be connected to a MicroLib cache module.

The following MicroLib caches have currently successfully being wrapped:

• Non-blocking cache (CacheWBNB)
• Multi-port non-blocking cache with victim cache (CacheWBNBVCMultiPorted)
• Multi-port non-blocking cache with timekeeping victim cache (CacheWBNBTKVCMultiPorted)
• Non-blocking cache with stride prefetcher (CacheWBNBSP)
• Non-blocking cache with content directed prefetcher (CacheWBNBCDP)
• Non-blocking cache with content directed prefetcher and stride prefetcher (CacheWBNBCDPSP)
• Non-blocking cache with tag prefetcher (CacheWBNBTP)

The following caches were not wrapped yet because they use a different interface:

• Multi-port non-blocking cache with timekeeping (CacheWBNBTKMultiported)
• Multi-port non-blocking cache with tag correlating prefetcher (CacheWBNBTCPMultiported)
• Multi-port non-blocking cache with dead-block correlating prefetcher (CacheWBNBDBCPMultiported)
