Like other Ubicom network chips, The IP3000 family processors have been designed with close attention of requirements of wireless networking and packet processing.

The first family member, the IP3023-250, is ideal for 802.11a/b/g devices, such as routers, bridges, and access points.

Ubicom claim, IP3023 has been proven to deliver up to three times the performance of comparable ARM- and MIPS-based SOC solutions.

IP3023 implements techniques such as:

Eight-way multithreading, allows the device to effectively operate as eight separate processors. Six otf the threads can be dedicated to I/O operation.
Zero-cycle context switching.
Memory-to-memory architecture, allows direct manipulation of packets in on-chip memory at full speed, eliminating the need for caches.

Folowing table, directly from Ubicom, show comparation between IP3023 and IP2022.
