3.6.3.6. Level 2 Memory System

The Level 2 (L2) cache controller handles requests from the L1 instruction and data caches, and snoop requests from the L3 memory system. The L2 memory system forwards responses from the L3 system to the core which can then take precise or imprecise aborts, depending on the type of transaction.
The L2 memory subsystem has the following key features:
  • 4-way set associative, configured to 128KB
  • Cache lines have a fixed length of 64 bytes
  • ECC protection for tag, data and L2 data buffer RAM structures
