1、K230的大核CPU是几核的,vector是每个核都支持吗? 2、vector的矢量执行单元是否可配置 3、矢量寄存器的位宽是多少 4、是否支持双倍矢量执行单元

大核CPU是单核,支持vector。
Sorry, something went wrong.
矢量计算单元的主要特点

@stoneqw 单核、只有大核支持 可配置指的是配置什么? 128bits,虽然C908支持256,但是K230上是有一些限制的 双倍矢量执行单元是指 128bit时有两倍资源可用?如果是这样的话那不会,我们是配置好的128
您好!请教一个问题,就是我通过vsetvli指令,比如这个指令vsetvli reg1, reg2, e64, m2 ; 如果vlen是128bit的话,那么m2的意思就是我把两个向量寄存器当作一个使用,相当于对寄存器分组,这样位宽就变成了256bit了。这和您说的支持256bit是一个意思吗?在这个架构下,如果可以通过vsetvli指令可以对寄存器进行分组的话,那么最大可支持将多少个寄存器分为一组呢?感谢感谢!
