ARM designs plenty of peripherals. Nearly all ARM SoCs use a PL011 UART, quite a bit have SMMUs, the Mali GPU is an ARM design, etc.

And they work very very closely with fabs; you can't really design highish performance cores like their's without working with the fabs. You'd have all sorts of weird bottlenecks, and wouldn't hit a competitive frequency (think under 100Mhz if you didn't take into account fab design rules).

What they don't do is sell predesigned SoCs (outside of dev systems). They give you all of the tools you need to integrate your own SoC so that you can take nearly all of the capital risk.

Huh i guess i made a bad assumption. Though i'm not surprised they make peripherals and work with the fabs, i just assumed it stayed away from it as much as it could.

edited my comment, thanks for the info!
