Can I hook up my ARM1176 to a L2 cache ?

Applies to: ARM1156, ARM1176

Answer

Yes, there are ports supplied on the ARM11 interfaces which could be used by a L2 Cache controller unit (L2CC) (e.g. the ARM L220 L2CC). You would hook up the ARSIDEBANDI/ARSDIDEBANDRW ports to the L220 if you wanted the L2 cache to exhibit inner cache attributes (i.e. the same as the core). You would hook up the ARCACHEI/ARCACHERW ports to the L220 if you wanted the L2 cache to exhibit outer cache attributes. Other AXI data/instruction port signals like AWPROTRW/I or WSTRBRW/I etc. can also be used by the L220 to monitor transactions from the core.
