OPB-to-PLB bridge

Hi,

I need to access a PLB slave from the Microblaze CPU via the OPB-to- PLB bus. The PLB slave requires a cache line when written to. Can I generate this? It seems to me that since the Microblaze only writes byte, half-word or word to the OPB-to-PLB, the bridge will never do a line write on the PLB. Any suggestions?

Thanks, e

Hey eascheiber,

You can write your own bridge for this purpose.

You know exactly what type of transfer the slave will accept. A stripped-down PLB master is quite easy to do (without Xilinx IPIF).

Regards, Marc
