Hi Jackckang,

Thanks for your help offer. Our main shortcomings are the lack of VIP for AMBA buses and a debugger. Any help on these areas are much appreciated.

Are you guys taping out soon? Which tech? Are you using commercial IPs?

It's great to see more and more adoption about RISC-V! Onchip team, please let us know if there's anything we can help with.

SiFive has also announced the Freedom Everywhere Platform, a RISC-V based microcontroller that will be commercially available. You can learn more at dev.sifive.com.

Yes, the micro has integer multiplication and bit manipulation. It sports aswell interrupts, timers, DPLL and even a test block of CMOS 1-poly NVRAM. 

Although we are still far from a full-featured low-end microcontroller as the SAMD21 on the Arduino-zero, the core performance is similar to it and it has enough peripherals to reproduce a lot of arduino applications. 

RISC-V ISA still young but most of the instructions subsets you mentioned have been already released. The growing momentum and industry attraction is a sign of a strong-possible soon commercial product. Keep tune!

Don't believe everything you read on wikipedia. -.-  (yes, it has atomics, integer multiplication, and more).

Wikipedia says this:

The RISC-V instruction set was designed in part for research, and therefore includes extra space for new instructions. Planned instruction subsets include system instructions, atomic access, integer multiplication, floating-point arithmetic, bit-manipulation, decimal floating-point, multimedia and vector processing.

No interger multiplication? No bit manipulation? I hear people talking about how this is going to replace ARM, but it looks to me like it is really just a research processor. It is certainly good for university groups to experiment with, but I think it needs a lot more development before anyone is going to take it seriously in the commercial sector.

If you're interested in knowing more about this project, Onchip will present at orconf (http://orconf.org) in Bologna next month. We still have a few seats left at the conference, and for those who won't be able to join us, the talks will be recorded and made available, just like the previous years
