OPB bus burst transfer support?

Dear All,

Does OPB bus(V2.0) included in Xilinx EDK6.2 support burst transfer mode (fixed burst or variable burst)? If yes, how many data can it transfer(read/write) at one operation?

The OPB inclued in the EDK supports burst transactions. However, a potential limiting factor may be some of the IP that we deliver which doesn't support burst transactions (for instance, the MicroBlaze I and D Master OPB connections do not support burst currently).

Hi Matt,

If we write our own IP Master that supports burst transfers and attach it to OPB along with microblaze. Will the system work?
