Hi experts,
I want to knows why there are 4 core cores per cluster in ARM big.Littte architecture?
Is it possiable if we make more cores per cluster? if not, what is the limitation?
I suspect it's just a question of "4 is enough" for most use cases. Why complicate the design with more cores than most uses cases actually require?
Peter,
but there are for example the LS1088A, which comes with 8(!) A72 cores. But in two clusters of 4. But we'll never know why, NXP/Freescale did it.
I never saw more then 4 cores in a cluster, so there must be some limiting factor.
