Detailed Description

This class represents the full configuration of caches of a processor.

Constructor & Destructor Documentation

otawa::hard::CacheConfiguration::CacheConfiguration ( const Cache *  inst_cache = 0, const Cache *  data_cache = 0  )

inline

Build a new configuration from the passed cache.

Build a cache configuration.

For creating a no-cache configuration, do not give any cache in argument. If you want to create an unified cache, pass the the same cache as inst_cache and data_cache.

Parameters

inst_cache	Instruction cache.
data_cache	Data cache.
icache	Instruction cache.
dcache	Data cache.

Note

To get an unified cache, use the same value for icache and dcache.

Referenced by load().
