Preliminary Data Sheet
PowerPC 440 Processor
The PowerPC 440 processor 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
Floating Point Unit (FPU)
The chip has a built-in super scalar FPU that supports both single- and double-precision operations, and offers
single cycle through put on most instructions.
Features include:
Five stages with 2 MFlops/Hz
Hardware support for IEEE 754
Single- and double-precision
Single-cycle throughput on most instructions
Thirty-two 64-bit floating point registers
SRAM Controller
The internal SRAM controller (ISC) supports the following features:
One bank (Bank 0) of 16 KB configurable as 4KB, 8KB or 16KB (128 bits wide)
128-bit slave attachment addressable by any PLB master
Transfers by PLB slave cycles:
– Single-beat read and write (1 to 8 bytes for 64-bit masters, 1 to 16 bytes for 128-bit masters)
– 4-word line read and write
– 8-word line read and write
– Double word read and write bursts for 64-bit masters
– Quadword read and write bursts for 128-bit masters
