O2P – Software Defined Radio (SDR) Processor

The processing of OFDM (Orthogonal Frequency Division Multiplex) based 4G signals requires far more processing power than the equivalent 3G or 2G.  The large signal bandwidth used by 4G technologies, and the usage of sophisticated, advanced antenna techniques such as MIMO (Multiple In Multiple Out) pose a significant challenge for baseband chip designers.  There is a need to combine a high degree of flexibility and programmability in a chip solution, with very high performance and low power consumption.

DSP (Digital Signal Processor) cores, which were once considered ideal for implementing older generation GSM and CDMA basebands, are not capable of delivering the intense processing required by 4G.  An industry trend for meshing several general purpose DSP cores has emerged, at times dubbed SDR (Software Defined Radio) which addressed the performance shortage.  However, it resulted in high power consumption, excess heat generation by the chip and quick device battery discharge.

O²P is a completely new architectural approach to solving the flexibility/performance/power paradigm.  Designed and optimized from its atomic level up to the switching fabric, to process 4G/OFDM signals, the O²P processor is capable of performing more than 16 GIGA MACS (Multiply Accumulate per Second) per second operations while consuming a fraction of the power of any communications-optimized DSP in the market.  Harnessing such extreme processing capabilities enables the O²P SDR to cope with not only 4G processing but also with legacy 2G/3.5G technologies. The O²P’s architecture is software defined to support various combinations of 2G/3.5G standards (e.g. LTE/WiMAX in conjunction with EDGE/HSPA) simultaneously, implementing a true roaming-capable, multimode “world” solution.
