While they could easily drop in a BOOM core, there would be some very non-trivial costs for SiFive to verify the IP and tune up the performance and feature set to match their costumers' needs. A lot of work has been put into Rocket once it made the transition from academic to professional and they would have to do that again for BOOM.
- jabl 9y agoAlso, there was quite recently a BOOMv2 paper describing some improvements, and hints of low-hanging fruits for further work. So I wouldn't be surprised if we'd have at least BOOMv3 before anybody commits to taping it out on ASIC.
- monocasa 9y agoThe BOOMv2 authors apparently had taped it out in TSMC 28 nm HPM.
- phkahler 9y agoYou just wrote that in response to a comment by one of the BOOM and BOOMv2 creators. And yes, there was more than just hints at low hanging fruit, so I'm hoping a v3 is in the works. But all those guys seem to be incredibly busy just giving birth to this (risc-v) thing. BTW, just to put it in writing I'm estimating the BOOMv2 clock at 2.5GHz on 28nm. Depending how much IPC they clawed back it might match the A15 on coremark.
