RISCV ?

Sure, lots.

http://www.ensilica.com/ip/ - 16 & 32-bit RISC CPU IP, AMBA bus, peripherals (both digital and analog) and other stuff. They also offer design services so can do other parts of the design for you, including the physical implementation and manage production.


SRAM + Flash would probably come from your foundry or specialised IP provider though. It's standard practice to work with multiple IP suppliers on a project.

MIPS + ARC upfront licensing fees are higher, but their processors are better than the M0.

However, $40k is not all you will pay with ARM. You'll pay a high royalty on top of that. So you need to look at the total cost over expected volumes. Other CPUs (like EnSilica's) will probably work out cheaper. Also, you need to consider the cost of s/w development tools on top. Some have free options, others don't.

--- Quote from: coppice ---That $40k is the probably the smallest cost you will have in the whole process, so why worry about the competitors?

What you say is probably true, but I want to know as a comparision, fact being ARM has been a leader in the IP sector long enough so needed to know the competitors pricing.

This is amazing, can you toss up a few more name's, just for comparison. Also have you tried their offerings.

Haven't done much research on that one so don't know what to expect, Same probably goes  for Ensilica's offerings.
I would have preferred to stick to one of the popular ones floating around at the moment, but things can still change.

EnSilica are in the UK, so probably convenient for you, assuming your flag is correct. I know them quite well  ;) Cadence & Synopsys both have their own CPUs, associated IP and offer design services in the UK, but will be significantly more expensive. (Of course, IC design isn't cheap wherever you go :P)

There are lots of other IP providers + design services companies. But not so many who do everything.
