Is there any RISC-V Processor with Vector Extension?

[Jongsang Yoo]

Hello.

I am Yoo Jong-sang who is doing a master's program in the ESCA laboratory of computer science at Korea University located in Korea.

I'm currently interested in implementing a Custom Vector instruction. Is there a core that supports Vextension in Chipyard?

If not, is there a related open source to support?

Best Regard,

[Jerry Zhao]

I hope to open source our implementation within a month from now.

Thank you for your answer.

How can I search in the future to find related information?

I also wonder if you have any additional plans to be integrated into Chipyard

Yes, it will be integrated into Chipyard. I'll likely send an email on this list when it is ready.

There is an open-sourced for RV vector ISA but it was built on the top of Boom core

I thought Rocket-Chip had already added Vector Extension support? Is it not the case?

The vector unit for Rocket and Shuttle will be released soon, with chipyard integration.
