Cortex-A35

The Cortex-A35 processor is Arm’s most power-efficient application processor capable of seamlessly supporting 32-bit and 64-bit code. Supports one to four cores with automatic data cache coherency, a shared Level 2 cache, 128 bit ACE, CHI or AXI system bus interface. 

The A35 has thirty-one 64-bit general-purpose registers instead of fifteen 32-bit registers in the A7.
