why Mali G71 uses multiple L2 caches

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.

  • It is a single logical cache implemented in multiple physical parallel slices. The number of cache slices used in a design increases as the number of shader cores increases, allowing more parallel reads and writes as the bandwidth requirements of the design increase (as all cache slices can be accessed in parallel).
