-//	2. no priorty arbitor , 8 masters are processed in a round

-//	3. if WB_USE_TRISTATE was defined, the share bus is a tristate
-//	   bus, and use less logic resource.
-//	4. wb_conbus was synthesis to XC2S100-5-PQ208 using synplify,
-//     Max speed >60M , and 374 SLICE if using Multiplexor bus
-//		or 150 SLICE if using tri-state bus.
