Re: IEEE-1394 (aka FireWire) Core

why not just using an existing link layer chip from Philips (if they still exist) or TI?

AFAIR there is only one (very old) chip (TI TSB something) that has firewire and can connect to an FPGA ... all the others have PCI or PCIe

just had a quick look at
http://www.semiconductors.philips.com/products/connectivity/1394/index.html

The Philips PDI1394L40 is still alive. This one is easily interfaced with an FPGA. We have been quite happy with it.

It was also used in a few other commercial audio products, e.g. in Mark of the Unicorn's audio break-out boxes, along with a QuickLogic FPGA and an 8051.

The advantage here is, that the chip can easily pass the isochronous data to the FPGA, so that the CPU does not need to handle these at all. This makes sure, that you won't need a lot of MIPS, as the CPU will only handle the asynchronous traffic.


Best regards, Felix
