Opencores website was really useful during my undergrad days. Thanks Damjan for it. Am bit skeptical about the success of another CPU core competing with ARM. The royalty of ARM is around 1-2% which is almost free. So the no royalty argument may not fly. BTW any IP issues with ARM/Intel ?

One reason people don't like royalties is the costing of counting sales and working out what is owed. So 0% is preferable to any% on that basis.

Which ones are the ARMv2 implementations? Those are very old and I were, I think, the Acorn RISC Machine as used in some Acorn computers running RiscOS.

The ARM royalty is usually calculated by the foundary such as TSMC. They know which devices have it and how many wafers have been run, so the accounting isn't that hard. Of course, no royalty is easier. It will be interesting to see how much of the pie Beyond can get.

The beauty about royalty is you will only end up paying significantly for successful chips ie ones you make a lot of and presumably make some revenue from. Paying an upfront fee means you take all the risk and costs upfront and this might force the vendor to make the fee so low to attract customers that it is not viable

Interesting legal position, given the BA processors are based on the OpenRISC architecture, the implementations of which are licensed under LGPL.

Beyond Semiconductor owns all including commercial rights to the OpenRISC architecture. Furthermore, the BA2 processors are not based on OpenRISC architecture but on much more efficient architecture proprietary to Beyond Semiconductor.

THe initial one time license fee still apply. Royalty/ device sold is free.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
