DesignArt Networks Ltd, which originally pitched itself as a developer of silicon for WiMAX infrastructure, announced a SoC "platform architecture" that integrates backhaul capability with WiMAX and LTE base station functions. The device is based on multiple ARM cores.

The fabless chip company's DAN2400 IC is its first product.

The DAN2400 is an open WiMAX SoC platform, based on a software-centric, multicore architecture, designed for networking. The chip includes PHY and MAC functions for a mobile WiMAX base station and includes a DSP core to control a six-channel antenna module, an embedded high-capacity network processor and several control plane CPUs.

The company did not say what process technology the DAN2400 has been implemented or where the silicon is being fabricated.

According to the company's website, the CPU subsystem is based on "multiple ARM cores." The network processor is based on multiple unnamed RISC engines. However, Tensilica Inc. announced that DesignArts was designing in several Xtensa LX2 configurable processors to handle PHY and MAC functions.

"As more cells are needed for increased coverage and capacity, an underlay network of cost-effective and compact outdoor and indoor micro, pico and femto cells is required to complete the macrocellular network. The backhaul of these cells is one of the most critical impediments for 4G roll-out," said Oz Barak, CEO, DesignArt Networks, in a statement.

DesignArt's SoC supports macro, micro, femto and picocell base stations and all integrated backhaul topologies, the company said.
