Hi,

I would like to know where can I get the information on the Latency of vector instructions in gem5. I am mainly interested in the latency of arithmetic vector instructions and Memory vector instructions used in the Gem5 simulator.

Regards,
Sonia

Ok. Does that mean all the vector instructions are using the constant latency?

Yes. A proper latency model is planned, but we're currently lacking people working on this...
