| Up to 800 MHz CPU, Integrated PCI Express* to PCI-X* Bridge, Application Accelerator for RAID 6, and Dual-ported Memory Controller Delivers Superior Performance |
|
High-performance, I/O processor based on Intel XScale® technology The
Intel® IOP333 is a highly integrated I/O system-on-a-chip for RAID on
Motherboard and I/O-intensive storage, networking, and communications
applications. The IOP333 features an 800 MHz CPU, high-performance
internal bus, dual-ported memory controller, high-bandwidth PCI Express
to PCI-X bridge, an application accelerator tuned for intelligent RAID
6, and an improved interrupt controller to provide a high-performance,
highly integrated processor solution. Target applications include RAID
on Motherboard and PCI Express host-based adapters (RAID cards, iSCSI
cards, FC cards, Security SSL NICs, etc.), and a host of other
intelligent I/O applications that require a highly integrated,
high-performance system-on-a-chip processor with an integrated PCI
Express interface.
As Intel's next-generation I/O processor, the
Intel® IOP333 continues to build on Intel's strength in delivering high
performance, low-power Intel XScale microarchitecture processors. It
integrates Intel's Superpipelined RISC Technology with a 7-stage
integer/8-stage memory superpipelined core, 32 Kbyte data and
instruction caches, and operates up to 800 MHz. The IOP333 is
code-compatible with previousgeneration Intel XScale microarchitecture
processors such as the Intel® IOP332, Intel® IOP331, and Intel® IOP321
I/O processors and other ARM*-based devices, simplifying code porting
from existing designs. It is compliant with the ARM v5TE instruction set
(excluding the floating-point instructions). The internal bus operates
at 333 MHz and offers internal bandwidth of up to 2.7 GB/sec. For more
information see the product brief.
