I must use a virtex5 with a PPC and a virtex6 without processor. The PPC (virtex5) must read and write some memory connected to virtex6.
I want know if it is possible to connect 2 plb bus from 2 fpga. With what solution?

Yes is easy answer,
how is the hard answer.
How fast do you want to do it ? How oftern ?
Simple , you could put say a rs232 on each plb, and wire across.
make both rs232 masters on the PLB, and away you go.
slow , but reliable.
at the other end,
You could put PLB <-> PLB bridges on each chip, and drive across say LVDS,
use DMA and it would be quite fast,

Thank, for your answer.
But a RS232 link is too slow for update the memory. I need update 2 memorys of 32Mbits.
With your solution, can I utilize a PCIe link for accelerate the transmission?

you can also try the xps_mch_emc core, which supports the burst like cacheline transfer.
And design a logic in V6 for the SRAM like interface
