Revision 1.16 – July 19, 2006  
440GR – PPC440GR Embedded Processor  
PowerPC 440 Processor Core  
Preliminary Data Sheet  
The PowerPC 440 processor core is designed for high-end applications: RAID controllers, SAN, iSCSI, routers,  
switches, printers, set-top boxes, etc. It implements the Book E PowerPC embedded architecture and uses the  
128-bit version of IBM’s on-chip CoreConnect Bus Architecture.  
Features include:  
• Up to 667MHz operation  
• PowerPC Book E architecture  
• 32KB I-cache, 32KB D-cache  
– UTLB Word Wide parity on data and tag address parity with exception force  
• Three logical regions in D-cache: locked, transient, normal  
• D-cache full line flush capability  
• 41-bit virtual address, 36-bit (64GB) physical address  
• Superscalar, out-of-order execution  
• 7-stage pipeline  
• 3 execution pipelines  
• Dynamic branch prediction  
• Memory management unit  
– 64-entry, full associative, unified TLB with optional parity  
– Separate instruction and data micro-TLBs  
– Storage attributes for write-through, cache-inhibited, guarded, and big or little endian  
• Debug facilities  
– Multiple instruction and data range breakpoints  
– Data value compare  
– Single step, branch, and trap events  
– Non-invasive real-time trace interface  
• 24 DSP instructions  
– Single cycle multiply and multiply-accumulate  
– 32 x 32 integer multiply  
– 16 x 16 -> 32-bit MAC
