This application note demonstrates the use of the Multi-Hannel (MCH) On Chip Peripheral
Bus (OPB) External Memory Controller (EMC) in a MicroBlaze™ processor system. The MCH
ports of the MCH OPB EMC connect to the cache ports of the MicroBlaze processor to allow
efficient cacheline accesses by the processor. The OPB Central DMA controller is also
included in this system to illustrate the capability of the MCH OPB EMC to handle cacheline
access from MicroBlaze processor and OPB sequential address (burst) transactions on the
OPB from the OPB Central DMA controller simultaneously.
