请问，J3/J5 双核的BPU在结果输出时是如何做验证，两个核是跑一样的模型还是不同的呢？BPU里做的工作我能理解是做了语义分割和目标物识别，那结果给到CPU，在CPU 里主要完成什么样的工作呢？

Lv.2你好，今天看到了这个帖子，我这边从工具链角度来答复一下这个问题。
J3/J5都是双核的，主要用于多任务场景，例如并发处理多个摄像头的数据、一个计算平台上并发处理多个任务。以J5为例，目前只支持编译单核模型，也就是同一时间，该模型只能在一个核上跑，J3上支持编译双核模型，这是把模型在编译器层面进行的拆分，用户层面不感知。关于BPU与CPU的区别，简单来说，BPU是加速核，主要处理的是int8/int16等量化后的数据，CPU处理float类型的数据，比如有些算子BPU不支持或精度不符合预期，此时我们就可以使用CPU来运行该算子，并不是把场景细化到某个计算核上。
