Abstract
The cache (10) is provided with a plurality of cache blocks (12), each having a plurality of cache lines. Each cache block (12) has one synonym entry at most. One cache line of at least one of the cache blocks (12) is selected based on the virtual address. If this cache line points to synonymous entries in other cache blocks, access is had to these, depending on whether a writing or reading operation is signaled to the cache and whether the readability and/or the writability flags for the cache cell entry selected by the virtual address is set or not.
