Maybe you're thinking something else.. But for example, 1710 TRM says: ARM926EJ L1 32K-byte, four-way set-associative instruction cache L1 16K-byte, four-way set-associative data cache with write buffer Then 2430 TRM says: ARM1136JF-S 32K-byte instructions and 32K-byte data--4-way associative 64-entry instruction and 64-entry data memory management units (MMUs) So no L2 until 34xx I believe.
