Phoronix: OpenRISC Emulator In JavaScript Can Run Wayland

An interesting open-source project pointed out to Phoronix this week was an OpenRISC emulator that's written in JavaScript. Making things more interesting is that it can now even run Wayland and a Linux image with keyboard support while being able to use JavaScript and other common open-source programs from this JavaScript-based emulator that runs in modern browsers...

About 40-80 mips on my i7 netbook. Its pretty impressive I did have to make sure I had power management mostly disabled cause it throttles down if I don't.

I wonder if this app is more useful (especially with Wayland support) than a painting of a panda's ass.

Just for reference ...

How does Wayland run on that? For comparison purposes:

• Intel i486DX2/66: 54 MIPS
• Intel Pentium/100: 188 MIPS
• ARM 7500FE (Acorn RISC OS Network Computer), ARM3.5running at 40 MHz: 35.9 MIPS
• ARM11 (Nokia N97, iPhone), at 412 MHz: 515 MIPS
• ARM Cortex M0 (the slowest modern processor available, it consumes about 0.67 miliwatts running at full power), 50 MHz: 45 MIPS.

Poorly... but it does run. It seems to lock up after interacting with it a bit though. I imagine wayland would run acceptably with some sort of acceleration. In this cases none of the drawing is accelerated.

Ok let me get this straight, We have this processor, with and OS already on it, and a browser running on top of it, running a java script process on top of that, running they machine instruction cycle of another processor, that is running and OS that can run a browser, that can run JavaScript, that can emulate another processor that can...

Is this a vanity project or is it useful in some way that I missed?

A webgl backend?

I don't think there are other OpenRISC emulators, in which case any emulator for it is useful, of course.

And there is another one: http://opencores.org/or1k/Or1ksim

In this case, it's only useful to let people use an OpenRISC system in their browser, e.g. when they don't have their OpenRISC development environment around
