PowerPC 440 Processor Core
The PowerPC 440 processor core is designed for high-end applications: RAID controllers, routers, switches,
printers, set-top boxes, etc. It is the first processor core to implement the Book E PowerPC embedded architecture
and the first to use the 128-bit version of IBM’s on-chip CoreConnect Bus Architecture.
Features include:
Internal Buses
The PowerPC 440GP features three IBM standard on-chip buses: the Processor Local Bus (PLB), the On-Chip
Peripheral Bus (OPB), and the Device Control Register Bus (DCR). The high performance, high bandwidth cores
such as the PowerPC 440 processor core, the DDR SDRAM memory controller, and the PCI-X bridge connect to
the PLB. The OPB hosts lower data rate peripherals. The daisy-chained DCR provides a lower bandwidth path for
passing status and control information between the processor core and the other on-chip cores.
Features include:
