Need 30GB data streamed at 500MB/sec to C6678 EVM, what hardware will support it?

Joel Graber

I have a C6678 evm for building a demo system. The application needs a ~500MB/sec input stream, slurping an entire file from a ~30GB selection of data.

The closest thing I can find seems to be a PCIE x4 SSD card. Since C6678EVM has only PCIEx2, the x4 card would have to auto-negotiate downward.

Does that seem like the right track?

Are there any device drivers or libraries for C6678 to access PCIE disk drives?

What else would I need?

Hi Joel,

I recommend you have a look at SPRABK8 - PCIe Use Cases for KeyStone Devices.

There are some throughput measurements included ...

Kind regards,

Thank you for that pointer. The benchmarks show >~600MB/s for 2 lane PCIe, so it looks like I'm on the right track regarding throughput.

This link: http://linux-c6x.org/wiki/index.php/Roadmap suggests that there are not PCIe drivers for C6678 available yet.

Hi Joel,

under Linux there should be drivers available - but not for Windows.

Thank you, I'll look there and dig in, in more detail.

Meanwhile, I need to hook up the External 80pin Expansion bus to get diagnostic data output.

The BOM for the C6678 EVM lists it as TEST_PH1 FEMALE HEADER 2x40P 1.27mm 180D(F) SMD 22L8742

I can't find a matching male connector on eg digikey.

Any idea where I can find a male header --ribbon-cable--male header that will plug into this connector?
