Reference system: MCH OPB EMC with OPB central DMA

Posted: 16 Apr 2007 ?? ?Print Version ?Bookmark and Share

Keywords:MCH OPB EMC? MicroBlaze processor? OPB central DMA?

This application note demonstrates the use of the Multi-CHannel (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.
