ARM Cortex-A510

The ARM Cortex-A510 is the successor to the ARM Cortex-A55 and the first ARMv9 high efficiency "LITTLE" CPU.^[1] It is the companion to the ARM Cortex-A710 "big" core. It is a clean-sheet 64-bit CPU designed by ARM Holdings' Cambridge design team.^[2]

Design

The Cortex-A510 is a “LITTLE” CPU core focusing on high efficiency,^[3] bringing the following improvements from last gen:

• 3-wide in-order design, the Cortex-A55 was 2-wide.^[4]
• 3-wide fetch and decode front-end as well as 3-wide issue and execute on the back-end, which includes 3 ALU's.^[5]

• 35% performance uplift compared to Cortex-A55
• 20% more energy efficient than Cortex-A55
• 3x ML uplift^[1]

ARM announced a refresh for the Cortex-A510 CPU core on 28 June 2022 along with other CPU cores.

The refresh improved power efficiency by 5% and scalability from 8 cores to up to 12 cores.^[6] Additionally, the refresh could be configured with 32-bit support, whereas the original was 64-bit only.^[7]
