This is where the Milkymist project is different - you can implement the SoC on a small, affordable FPGA and still get good performance, in part thanks to dedicated accelerators. By the way, there is also FPGA platforms for OpenSPARC so your estimate is too high, but they're still quite expensive and OpenSPARC runs pretty slowly on them.

The LM32 _is_ a good example of open source CPU; and there's more to open source than GNU. Also, it is simply more technically appropriate here than LEON, OpenRISC and OpenSPARC. There was some confusion about the LM32 license (sparkled among other things by confidentiality notices left in the source files) but Lattice cleaned up most of the mess a few months ago. The Lattice license says: " The Provider grants to You a personal, non-exclusive right to use object code created from the Software or a Derivative Work to physically implement the design in devices such as a programmable logic devices or application specific integrated circuits." So - yes, we can implement it in non-Lattice FPGAs. There is no MMU; some people talked about building one but it did not happen. We are open to switching to OpenRISC should it become as small and fast as LM32.

Submission + - Open Source CPUs Coming to a Club Near You? ( 1

lekernel writes: The Milkymist project have started shipping their so-called "video synthesizer", a device used by concert and other event organizers to create live visual effects. Most interestingly, the device is based on their fully open source system-on-chip design, including both a CPU and graphics accelerators — the latter being a significant part of what Open Graphics is still struggling with.

Submission + - A Free and Open Replacement for Wireless LAN ( 3

dvdkhlng writes: Qi-Hardware, the community that brought us the Ben NanoNote handheld computer, have just released their next piece of all-out free and open hardware: the AtBEN+AtUSB wireless dongles. Aiming for a solution that works without proprietary firmware blobs, WLAN compatability was abandoned. Instead the project went for simpler, yet more open 6LowPAN technology.

The first batch of AtBen+AtUSB dongles is now ready for shipment trough Tuxbrain. Designs and source code are available under GPL and CC licenses.

I do not make any special effort to sound negative here, but honestly that SoC did not really work on anything. Most of the stuff posted to Opencores is in fact half-finished, buggy projects, and Milkymist SoC does not use any other Opencores stuff than Wishbone (and still, this was because of LM32) for this very reason. Even the OpenRISC GCC/glibc toolchain was crippled with various major problems until recently. The OpenRISC RTL still is, but I can see things moving in the right direction. Maybe Milkymist SoC will integrate OpenRISC at some point, if those technical improvements happen. OpenSPARC and LEON were also considered, but they are very heavy resource-wise.

We considered this option, but OpenSPARC is very resource hungry. It is a good design for a stand alone ASIC microprocessor, but in our case it is better to use a small and resource efficient CPU and leave the bulk of the calculations to dedicated accelerators.
