你好:
对fpga感兴趣,正在调研
请问你用的fpga板子大概多少钱,是什么芯片
它跑forward的速度能更具体的描述吗,比如多大的图片,和gtx1080比较性能上是多少倍的关系
方便的话能加个微信啥的吗?
非常感谢!

xc7v415t,只是仿真;处理的是128*128的图片;从之前的仿真结果看是0.3~0.5ms,gpu好像都至少1ms

您好:
您这是只是做了一层卷积、pooling吗?目前正在这方面,第一层卷积、MAX_pooling没问题,但是整个工程实现时,发现后面需要进行大量的重量化(归一化操作),不知怎么搞了。

xc7v415t 这个从哪里能够购买到?淘宝上能买到吗?好像搜不到呀。
问了小白问题了,不好意思,对这个方向很关注。

@zhlw2017 有三次卷积和两次池化,还有一次全连接。我没理解为啥后面需要归一化?

@jsxyhelu 这个很贵的,需要实验室支持。
