#2Let the battle begin! Wonder how RISC-V movement in the open source ISA front has influenced this decision.

#3Sounds really good. Is it only free as in free beer or editable too?
The interesting applications for RISC-V are Vector Extensions and other application specific mods.

#4Wow, not only FPGA-optimized Cortex-M1, they also releases Cortex-M3, one of the most popular MCU IP.
BTW, are there many applications integrating a MCU core with FPGA rather than a AP core? I only have seen Xilinx products that uses Cortex-A core.

Beer. Pretty sure they will be precompiled RTL blobs.

It is for Xilinx FPGAs only so at least it is not open-source friendly.

It's not unheard of to throw a soft core in there too, but in the past it'll be something like a Microblaze. An MCU vs. an AP are pretty orthogonal as it's pretty hard to cycle counting real time determinism out of an AP.

Came to the comments for the same question. The difference between beer and speech is important here, as the impact of a free-as-in-speech open-source design would be substantial.
Either way, thanks, ARM!

"DesignStart Eval enables completely free access to fixed-configuration Cortex-M0 and Cortex-M3 and full subsystem RTL for evaluation, prototype, teaching, and research. Available to all*, the packages can be downloaded instantly, requiring only a simple click-through agreement. "
and if you want to make a product,
"DesignStart Pro enables access to the full Cortex-M0, Cortex-M3, and subsystem RTL. Available to companies for commercial use with a no-risk, $0 license fee and success-based royalty model. Access to the IP can be requested online, requiring the signing of a simplified license agreement."
so free as in... kinda freeish free trial.

Not even. You have to pay a royalty to ship one of these M0 designs, still. It's just designed to be more appealing to research.
