How does the ARM CA53 4 core join NEON on only 2 cores?

win847

Our project only wants 2 cores to support NEON for cost reasons. How can I do this?

1. Can a single cluster be done?


2. Cut into 2 clusters, each with 2 cores. What is the difference between the performance of ARM HMP scheduling 4 cores and the performance of single cluster 4 cores?

    Hi,

    All of the cores in a Cortex-A53 cluster must have the same NEON configuration.

    If you want to study the impact of a single four core design versus a dual core, dual cluster I would recommend to use Arm Cycle Models. It would be easy to setup different simulations and assess the performance of various configurations.

    The models are built on a web portal called Arm IP Exchange with easy configuration to change parameters. 

    Let me know if you have any questions.
