Is there anyboay work on the subject with the embeded system |
|
|
Now I want to implement a arm core in the xilinx v4 or v2,but I
can't get the soft ip core,anybody konw how to get the free soft
ipcore,thanks!
Also If I choose the hardcore from alter or xilinx,which is
better?And what I need list below:an embeded hardcore(with some
peripheral devices) and pci-express interface .with the price and
performence,which is better?and the cpu core I need do'nt need high
speed. |

no. |
nothing more that I already told or what you can find yourself buy googling.
for fun I checked the design for synthesis pass, thats it.

google: nnARM
and you get the free opensource ARM softcore
but its pretty rotten, it does synthesize but is huge
http://xilant.com/content/view/21/55/
there is a little info about our testing of it
short: hardly useable
the only FPGA with hardcore processor and PCIe capabilities is the xilinx
Virtex4FX, Altera PCIe ready devices do not have hardcore processors

Virtex II Pro devices also have PPCs and are PCI-E capable. (Good luck
getting a V4-FX :) )

well, yes both V2P and V4FX are can be used for PCIe when exeternal clock
recovery is used. I think Xilinx claimed a little better confirmance to the
PCIe spec for Virtex-4, but very strictly taken none of the FPGA serdes
currently on market is 100% PCIe specification compliant, some features are
missing or out of required range
