      Um, it's an open standard (by some definition), not open source.

      From the SPARC website:

      Any version of the SPARC Instruction Set can be licensed from SPARC International, and then used to design processors implementing that open standard. Truly - in letter and in spirit, SPARC's open - for business!
      Hell, it doesn't even look like much of an open standard. You need to license the instruction set in order to be able to implement it. This is like saying UNIX is open source, since anyone can implement POSIX and license the UNIX trademark, and because a lot of people have licensed the source code. That's not open source; it may be an open standard (although I'd argue that in order to be an open standard, you can't restrict who implements it with licensing agreements). So really, SPARC is in no way open source, and I wouldn't even consider it an open standard.

      OpenCores, on the other hand, is really open source. You get the full design of the entire chip; you could just produce the chip by sending the CAD files to a chip fab and having them produce it. All of the Verilog/VHDL/etc. are open and freely available for you to use and modify. Even if you license the SPARC ISA, you still have to design the chip yourself.

      Hell, there are plenty of ISA's that you can license. The IA32 architecture is implemented by Intel, AMD, Transmeta, and others. PowerPC is implemented by IBM and Motorola. MIPS chips are produced by lots of people. Open ISA's are a dime a dozen. What's important about OpenCores is that the full chip design is completely open.

This is interesting, and it's maybe even more interesting that I haven't noted it in any trade journals (did I miss it, or has this thing been going on under the industry radar?)

    However, it seems like the CPU core itself is open-source, while a lot of the bonus features on the SoC (System On a Chip) example cited are IP from Flextronics (the the company that did the physical design for this open-source CPU core, which was manufactured by UMC). I can't tell for sure because the site is slashdotted already. The links on PCI, JTAG etc. would presumably tell if all these IP macros (besides the CPU) are open source also -- does anyone know for sure?

    Either way, the specs on the sample chip are interesting: SoC with OR1200 CPU implemented by Flextronics Semiconductor: 32-bit general-purpose microcontroller, UMC 0.18um fab process, maximum clock frequency of 160MHz. This SoC contains (1 each I assume): OR1200 processor, Memory Controller (FLASH, SDRAM, SRAM, DPRAM), PCI 2.2 32-bit interface 33/66MHz, Ethernet MAC 10/100. UART16550, GPIO, JTAG/Debug Interface.

    BTW, 160MHz is pretty darn good, until you see that 160MHz is not really "MAX" as in "max (worst-case) operating conditions" as one usually specs these things. Usually, when a spec says "maximum clock frequency", it means that you can safely run the part at these speeds under the entire range of allowed operating conditions (temperature and voltage). It's rather meaningless to tell the fastest it canpossibly go (which would be 0Kelvin, with a voltage almost high enough to fry the cip), so wpecs tend to tell you the max safe speed.

    That would be the highest temperature (usually ~70C, but it's really based on the junction temp, which is calculated from ambient temp, airflow, and package thermal characteristics -- higher than 25C in any case, since that's usually called "typical"), lowest voltage (usually nominal minus 5% or 10%; so for 3.3V system, worst case voltage would be 3.3-0.33=2.97V, for 1.8V core it would be 1.62V), and slowest process from the fab (whther this is the case or not is unspecified in the list). Instead, lower down the page I see:

    Max system clock 160MHz was obtained at 25C ambient temperature, 3.3V IO and 1.8V core

    I could take a wild guess and say the thing would run at least 125MHz (respectable for the tech at hand), so calling it 160MHz (but not at worst-case conditions) is a little odd, or at least non-standard. If it were a "normal" industry player quoting me a part's clock rate that way, I'd become very, very suspicious of them for the rest of the negotioations.

    It's still way cool, and if those IP cores are all available open source also, I'm really excited. But, I still have a lot of unanswered questions that I expected to see at least a brief mention of:
