The list might be interested in recent developments on another mailing list I follow, http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook, a list for discussing a completely free-software-compatible modular hardware design. In particular, I'm thinking of this recent message http://lists.phcomp.co.uk/pipermail/arm-netbook/2012-February/002278.htmlin which the project's leader Luke Leighton writes about the possibility of building a SoC including such features as... <blockquote> [...] create a new (entirely software-based) SoC that would be entirely FSF-Endorseable as it would be entirely software-programmable. [...] the company that i've found that has an alternative 32-bit RISC core not only has SMP cache coherency already done, but also they have an absolutely amazing set of Instruction extensions, including DSP, Audio, Video, Base-band (for RF handset processing) and much more. the plan is, therefore, to target this CPU at a very very wide range of markets, based on it having: * 8 CPUs at 1.2ghz or above * SMP Cache Coherency * 32-bit DDR3 1333mhz RAM (with a 2nd version having 2 DDR3 interfaces) * virtually everything software-programmable (with the exception of CABAC decode) meaning that it will do 3D graphics _and_ 1080p Video entirely in software. the interfaces i've selected so far will include: * HDMI Out _and_ In * 24-pin RGB/TTL * 2-channel LVDS * 2 PCIe (2-lane each) * USB-OTG, USB-2 and USB-3 * SATA-3 * NAND controller (8-bit with 4-way CS) * 3 SD/MMC interfaces * 3 SPI interfaces * 3 UARTs, 3 IIC interfaces, CAN-Bus, 2 PS/2, Touchscreen, 3 PWMs * 2 MPEG Transport Stream Interfaces * Smartcard Interface that means that it could be used in at least the following products: * Laptops, Netbooks, Tablets, Desktops, PCs, NAS-Boxes * PVRs, TVs, Set-Top Boxes, Satellite Decoders * Smartphones, Base Stations, GNU/Radio SDR Products bearing in mind that this will be out some time in middle of 2013, if it's started soon, i could reallly do with some help reviewing the interfaces and capabilities, to make sure i've got it right. </blockquote> If anyone here is interested in the possible intersection of Frank with this hardware project, please do get in touch with Luke, either directly or via the list. Jecel, perhaps you could critique the idea, given your experience with alternative (for want of a better term) architectures?
