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-A5xx 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
