>From my understanding. Qi-Hardware was going to follow PRC(Loongson) in developing a MIPS compatible CPU core. But as they were not able[sic] to develop a MIPS compatible CPU without a MIPS licence. As for the Nanonote moving to MilkyMist CPU Qi-hardware has already decided that NOT TO USE Lattice Semiconductor Corporation's LatticeMico32 Open Source Licensing, because no one could understand it. Go look up the discussion about is the LM32 license GPL compatible. The over summarize. Qi asked Lattice Semi if it is GPL compatible. and Lattice Semi replied, 'It's suppose to be, but no guarantee on it' to quote from Groklaw's _The_GPL_is_a_License,_Not_a_Contract,_Which_is_Why_the_Sky_Isn't_Falling_ http://www.groklaw.net/article.php?story=20031214210634851 Here is a definition of 'license' from Steven H. Gifis' "Law Dictionary, 2d Edition: "LICENSE: A right granted which gives one permission to do something which he could not legally do absent such permission; 'leave to do a thing which the LICENSOR [the party granting the license] could prevent.'" A contract, on the other hand, is defined like this: "a promise, or set of promises, for breach of which the law gives a remedy, or the performance of which the law in some way recognizes as a duty. I Williston, Contracts Section 1. The essentials of a valid contract are 'parties competent to contract, a proper subject-matter, consideration, mutuality of agreement, and mutuality of obligation.' 286 N.W. 844, 846: 'a transaction involving two or more individuals whereby each becomes obligated to the other, with reciprocal rights to demand performance of what is promised by each respectively.' 282 P. 2d 1084, 1088. 'The total legal obligation which results from the parties' agreement as affected by law.' U.C.C. Section 1-201." Lattice didn't never said what the LICENSE for the LM32 is outside the contract and the contract is(was did Lattice ever update it?) so complex you have to be a lawyer to understand it. So while the LM32 is open source hardware it is still undetermined it is copylefted hardware or not. > so far away that it's worth to change to a new temporary CPU for the Ya? exactly the point. The LM32 core in the MilkMist is also a temporary CPU. The last time I followed it they(MilkyMist and NanoNote folks) where trying to decide on if they wanted to still with LM32 compatible core or go with a different CPU architecture. which goes back to the debate of WinModem folk(like Werner Almesberger) vs. Accelerated Graphic Card folk(like Chuck Moore). Should the peripheral processors be tasked with any processing or should they be "Keeping the microcontroller's task simple and doing the heavylifting on the host...." That is from the Werner about switching from a uC with an 8051 CPU to one with a AVR(32?) CPU.
