Breakthrough Wireless Processor Architecture Cuts Power Consumption Dramatically for Multimode Broadband Wireless Devices
Premier WiFi Processor Validates WBSP(TM) as World's Lowest Power Baseband Technology
CommASIC announced, today, the successful realization of its three-year effort to implement a revolutionary architecture for broadband multimode wireless processors. Rigorous performance testing of the first processor implementing the new technology demonstrates that CommASIC's Wireless Broadband Signal Processor(TM) (WBSP) architecture offers huge benefits in terms of power efficiency, performance, and die size compared to conventional ASIC and DSP approaches. CommASIC is a fabless semiconductor supplier founded in 2001 to develop and implement WBSP.
Specifically designed for high performance broadband applications, WBSP is programmable, giving it so-called multimode capability (i.e., the capability to support multiple cellular (e.g., GSM, WCDMA) and WLAN standards as well as other broadband standards in a single CMOS processor). Integrated into a wireless solution, a processor implementing WBSP offers handset-class power consumption without compromising performance. A concrete demonstration of the advantages of WBSP can be seen in CommASIC's premiere product, a soon-to-be-announced WiFi baseband processor that will be the industry's most energy-efficient, most compact 802.11a/b/g solution.
WBSP, developed specifically to satisfy the rapidly emerging need for broadband wireless devices with multimode capability, offers several key advantages over conventional ASIC and DSP methods. A WBSP implementation of WCDMA, for example, is 1/5th the power consumption of comparative ASICs and half the die size. Compared to traditional ASICs, WBSP also offers considerably more flexibility, creating an easy migration path towards multimode implementation. Furthermore, WBSP is networking technology transparent, and because it is programmable, it can accommodate virtually any and all wireless standards, from 802.11 a/b/g to WCDMA to WiMax or others. Such multimode capability cannot be efficiently implemented using conventional approaches.
Debut of the CommASIC 802.11a/b/g baseband processor is expected to set a new industry benchmark for power consumption. Independent testing of pre-production samples show that the processor more than doubles talk and usage time and also offers the lowest standby power consumption in the industry.
The CommASIC 802.11a/b/g product is expected to be announced before year-end.
