双核A15占V7 2000T约 80%的资源。

ARM A5 dual core可以放在单颗v6 760里面,加少量外设。

ARM A7 双核单颗V6 760 可以放进去。 A9单核也可以放进去单颗V6 760,双核放不进去。

ARM A9 双核放不下820/760。A15更放不下。
ARM A9 4核放V7 2000T里面可以放得下。48MHz主频;主要问题在GPU。 GPU+单ARM占96%资源

双核A53: 4 core一般把vu440放满,外设放不下了;所以一般2 core放在vu440里面+部分需要放一起的外设。 双核A55:某案例占VU440约55%; 另外一个数据是 单核A55(+部分外设) 在VU440占50%; 双核A57......
双核A72......
双核A73: 某客户基于ARM v8指令集的自研CPU双核占单颗19P FPGA约60%资源。
双核A75:某案例占VU440约65%资源

待补充
