why Mali G71 uses multiple L2 caches

Son

Hi, I am jang-hyun Son, a college student from South Korea.

I will study Mali GPU with OpenCL, and before that, I am now studying about the Mali G71 architecture.

My question is that, Why are there multiple(actually 4) L2 Caches in the image above.

I think only one L2 cache is used for one GPU normally.

Thank you for reading my question, and i wish you a reply.

    Thank you very much. 

    Then, one more question comes to my mind. I found AMBA 4 ACE is used for cache coherency.

    Because of the multiple L2 caches, is it required to put AMBA 4 ACE under each of L2Cs for L2 cache coherency?

    I am sorry for multiple questions, and thank you again.
