Mobile WiMAX chip specialist picoChip will start sampling its third generation picoArray processors by mid year. The multi-core processors, dubbed PC202, PC203 and PC205, integrate around 200 individual processors on to each die and deliver over 100GIPs and 25GMACs.

The processors are fully backward compatible with picoChip’s 101 and 102 family of processors that are already designed into products from companies such as Intel, Airspan, Nortel, Fujitsu and Ericsson.

Two of the devices, the PC202 and PC205 integrate an ARM 926EJ-S 280MHz core for control and MAC functionality, the result of a partnership revealed last September. picoChip and Wintegra earlier announced a development platform for mobile WiMAX that integrates picoChip's PC102 picoArray DSP running its IEEE 802.16e PHY with the Wintegra WinMax access processor programmed with 16e MAC software for transport and backhaul.

According to Rupert Baines, vice president of marketing at picoChip, the multi-core processors are “the most competitively prices parts of its type, and are amongst the first to get near the $1/GMAC metric when ordered in volume”.

Reference designs are being readied for both 16d and 16e version WiMAX and W-CDMA cellular systems, including versions for HSDPA that will be software upgradeable to HSUPA.

The entry point PC202 is targeted at access points and client side CPE systems, but Baines stressed, “we will not go down to the handsets side of the business. And we have no wish to go head to head with potential customers such as Intel in for instance the lap-tops business.”

The PC203, with 248 processors, is firmly positioned for basestations and support for algorithms such as MIMO and beamforming. This is meant to be used with external control or network processors. The PC205, which also integrates 248 processors and is suitable for high signal processing needs of, for instance, software defined radios.

Airspan Demonstrated Its Low-Cost, "Pay-as-You-Grow" WiMAX Base Station at CeBIT 2006, and plans to begin shipments of its 3.5 GHz system in April 2006. Their MicroMAX-SOC, is based on the high-performance SQN2010 WiMAX Certified base station design of Sequans. Later in the second quarter, Airspan will introduce support for the 5.8 GHz TDD and 3.3-3.4 GHz TDD bands, followed by a range of other 3.X GHz and 5.X GHz products in second half of 2006.

Airspan's other car, their MacroMAX basestation, uses picoChip components to handle the added funtionality of beamforming and scaleable COFDM found in Mobile WiMAX.

The picoArray chip is said to improve price / performance by combining the price and programmability of a traditional DSP with the performance of a FPGA / ASIC.
