IMEC Flexible Air Interface Baseband Platform for Software Defined Radio

IMEC has completed design and tape-out of a flexible-air-interface (FLAI) baseband platform for software-defined radios (SDR). IMEC’s solution is an ideal basis to support upcoming generations of mobile devices featuring 802.11n, 802.16e, mobile TV, and 3GPP-LTE communication standards. The system-on-chip (SoC) platform and its patented components with their programming environment will be licensed to industry for commercial product development as white-box intellectual property (IP).

The FLAI platform incorporates two IMEC-proprietary ADRES (architecture for dynamically reconfigurable embedded systems) baseband processors fully supported by a proprietary C-code compiler, three digital front-end tiles with a proprietary ASIP (application-specific integrated processor) to assure sync-detection, an ARM(TM)9 processor, and optimized AMBA(TM) interconnect to link the SoC’s modules with on-chip memories. The IP blocks come with reference platform control software and reference firmware for IEEE802.11n, 802.16e and 3GPP-LTE, as well as integration support.

As a result of the patented platform control and power management approach, the SoC consumes only a few milliwatts in standby mode, yet is still capable of receiving an immediate burst from any supported wireless standard (reactive radio). When transmitting or receiving data bursts with multi-antenna encoding at more than 100Mbps, platform peak power is only 300mW.
