third one: in cooperation with ingenic we will be doing a JZ4775-based CPU Card, i have received the schematics and PCB EVB files just today, this is a dual-core 1ghz MIPS SoC with a dual 1Ghz X-Burst Vector Processor that can do i believe it's 720p video decode and 3D graphics. it's entirely software-based - no proprietary GPU or VPU - which means it will also be FSF Endorseable (hooray!). again we will follow their progress into next year's products, i would expect them to have a quad-core out that can do 1080p video decode which would be awesome if they did. power consumption is really low on the ingenic SoCs.
i will put this one with 1gb of RAM. the layout of the EVB is quite spread out, but i have made some measurements and it is *just* (barely) possible to leave the DDR3 RAM layout untouched, the SoC will almost be hard up against one edge and the RAM against the other: it is going to be very tight, so there will be no extra interfaces except for an SD/MMC Card. it does however have GbE which is fantastic, and there are two USBs (one USB 480mbit/sec and one 11mbit/sec) - i will route these both to the EOMA68 interface just out of sheer peversity.
more later as it happens.

Congratulations! Thanks Luke for supporting MIPS. I have been waiting for a MIPS CPU card. I can donate. Please private message me.
"Unfortunately, MIPS Release 5 has the VZ module to support hardware assisted virtualization." https://www.linux-mips.org/wiki/KVM Though there is little information on the internet on the VZ module, most likely it would be less of a surveillance threat than TrustZone and Mobicore.

Luke, I too would be interested in getting an FSF-endorseable card, so will be following your progress on this card.
Freebirds, you don't know the technologies you're talking about. From the linux-mips article about VZ: "The root is in full control of what the guest is permitted to do, which allows a guest operating system to run unmodified and unaware that it is being virtualised." If you are worried about TrustZone, then you should be equally worried about VZ.
Me, on the other hand, I would like to have hardware support of virtualization. I'm excited for this technology.

awesome.

derek, please do educate her... preferably patiently... :)

Are you sure that JZ4775 is dual-core?

These links show that JZ4775 is single-core.
Thanks.

yep thanks for checking that miguel, you're right it is.
