PowerPC 440 Processor Core
The PowerPC 440 processor core is designed for high-end applications: RAID controllers, SAN, iSCSI, routers,
switches, printers, set-top boxes, etc. It is the first processor core to implement the new Book E PowerPC
embedded architecture and the first to use the 128-bit version of IBM’s on-chip CoreConnect Bus Architecture.
Features include:
Floating Point Unit (FPU)
