The co-existence of numerous Wireless Networking standards, as well as the continuous development of new standards has created a demand for processing platforms that support multiple protocols while offering the required flexibility, efficiency and performance. The UniPHY™ DSP-core is the first ultra-high performance, fully synthesizable DSP core optimized for physical layer processing to address these multi-protocol requirements.
Optimized for the 3DSP family of synthesizable, high performance, low power SuperSIMD™ DSP cores, the programmable 802.11a/b softPHY baseband implementations incorporates all mandatory and optional Wireless LAN features and data rates per IEEE802.11a/b standards, while leaving headroom for future enhancements and standards The DSP baseband software consists of highly efficient assembly code that runs on 3DSP’s UniPHY™ core.
New standards will be added as they become ratified and deployed.

The unprecedented computational power of the UniPHY architecture, enables simultaneous operation of multiple WLAN applications and protocols, up to 3 different modulation / demodulation schemes in parallel. This enables access points to support different WLAN networks simultaneously or multiple channels for extended data rate throughput.
3DSP has five patent applications in process on the channel estimator, equalizer, and Viterbi decoder algorithms. These patents represent methods that greatly reduce the computational load and power consumption while maintaining or improving performance.
Advanced Filtering and AGC techniques are used for the best system performance and optimal matching with the RF radio components of your choice.
