Product Description
The Intel
high-performance parallel processing power and flexibility to a wide variety of networking,
communications, and other data-intensive products. The IXP1250 is designed specifically as a data
control element for applications that require access to a fast memory subsystem, a fast interface to
I/O devices such as network MAC devices, and processing power to perform efficient
manipulation on bits, bytes, words, and longword data.
The IXP1250 combines the popular StrongARM* microprocessor with six independent 32-bit
RISC data engines with hardware multithread support that combined, provide over
1 giga-operations per second. The Microengines contain the processing power to perform tasks
typically reserved for high speed ASICs. In LAN switching applications, the six Microengines are
capable of packet forwarding of over 3 million Ethernet packets per second at Layer 3. The
StrongARM* processor can then be used for more complex tasks such as address learning, building
and maintaining forwarding tables, and network management.
