External DMA Slave Support
External master interface
– Write posting from external master
– Read prefetching on PLB for external master reads
– Bursting capable from external master
– Allows external master access to all non-EBC PLB slaves
– External master can control EBC slaves for own access and control
Ethernet Controller Interface
Ethernet support provided by the PPC440EP interfaces to the physical layer but the PHY is not included on the
chip:
One to two 10/100 interfaces running in full- and half-duplex modes
– One full Media Independent Interface (MII) with 4-bit parallel data transfer
– Two Reduced Media Independent Interfaces (RMII) with 2-bit parallel data transfer
– Two Serial Media Independent Interfaces (SMII)
– Packet reject support
DMA to PLB 64 Controller
This DMA controller provides a DMA interface between the OPB and the 64-bit PLB.
Features include:
Supports the following transfers:
– Memory-to-memory transfers
– Buffered peripheral to memory transfers
– Buffered memory to peripheral transfers
Four channels
Scatter/Gather capability for programming multiple DMA operations
32-byte buffer
8-, 16-, 32-bit peripheral support (OPB and external)
32-bit addressing
Address increment or decrement
Supports internal and external peripherals
Support for memory mapped peripherals
Support for peripherals running on slower frequency buses
