PPC440SP
Description
Designed specifically to address high-end embedded applications for storage, the PowerPC 440SP Embedded Processor (PPC440SP) provides a highperformance, low power solution that interfaces to a wide range of peripherals by incorporating on-chip power management features and lower power dissipation.
Key Features
- PowerPC‚ 440 processor core operating at up to 667MHz with 32-KB I- and D-caches (with parity checking)
- On-chip 256-KB SRAM configurable as L2 Cache or Ethernet Packet/Code store memory
- Selectable Processor:Bus clock ratios (Refer to the Clocking chapter in the PPC440SP Embedded Processor User’s Manual for details)
- Three DDR PCI-X interfaces (32-bit or 64-bit) up to 133 MHz (DDR
- with support for conventional PCI
- XOR Accelerator with DMA controller
- Processor can boot from PCI memory
- Optional: High throughput RAID 6 hardware acceleration, performs XOR and Galois Field P & Q parity putations, supports up to 255 drives
- I2O Messaging Unit with two DMA controllers
- External Peripheral Bus (24-bit Address, 8-bit Data) for up to three devices
