ARM Cortex-A520

The ARM Cortex-A520 is a "little" CPU core model from Arm unveiled in TCS23 (total compute solution) it serves as a successor to the CPU core ARM Cortex-A510. The Cortex-A500 CPU cores series generally focus on high efficiency, the CPU core can be paired with the other CPU cores in its family like ARM Cortex-A720 or/and Cortex-X4 in a CPU cluster.

Improvements

 * 8% peak performance improvement over the Cortex-A510
 * Support only 64-bit applications
 * Up to 512 KiB of private L2 cache (From 256 KiB)
 * Add QARMA3 Pointer Authentication (PAC) algorithm support
 * Update to ARMv9.2
