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

win847 over 6 years ago

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...

Yes, Do you have any good suggestions?

I have learned that ARM's new DynamIQ multi-core design can fulfill my needs in a custle, but our IC design is now starting design, can not wait for the application of DynamicIQ multi-core design.
