FLAI takes lead in new generation mobile devices
( 01 May 2008 )
|
The flexible-air-interface (FLAI) baseband platform for software-defined radios (SDR) 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-propriety architecture for dynamically reconfigurable embedded systems (ADRES) baseband processors fully supported by a propriety C-code compiler, three digital front-end tiles with propriety application-specific integrated processor (ASIP) to assure sync-detection, ARM9 processor, and optimized AMBA 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.
Due to its patented 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. During data transmission or reception, the platform’s peak power is only 300mW.
The device features 38mm2 die area; four power domains, eight clocks; 270 I/O pins; 6.7Mb memory; two FLAI-ADRES processors, each with 33 memory macro at 400MHz; 32KB instruction cache; 128-entry configuration memory; 34KB data scratchpad and 400MHZ WCC clock rate.
In the near term, the FLAI platform will be combined with flexible radio front-end (SCALDIO) to demonstrate a fully operational software-defined radio. This platform achievement will be followed by a new generation of SDR research results, focusing on SDR and cognitive radio. This new generation also includes a unified application-specific processor architecture that can reduce the area cost of implementing multi-mode advanced forward error correction.
