Imagination Technologies recently rolled out its Ensigma Series4 radio processor unit (RPU) IP core line. The new Series4 family of RPUs introduces a highly efficient and high-bandwidth architecture, enabling support for the most demanding communications standards such as 802.11ac 2x2 MIMO and DVB-T2 in an optimal and low-power implementation. By adding new highly-specialised data processors combined with an upgraded internal data fabric, the latest Series4 RPUs deliver unprecedented performance and throughput ideal for next generation applications from connected home multimedia to advanced continuous data roaming.

The Series4 architecture uniquely combines fully programmable modulation and coding processors with multi-standard hardware accelerators and a multi-stream DMA (Direct Memory Access) fabric to yield a power and area optimised multi-standard base band solution. The core modulation and coding processor is complemented by an array of configurable, and in some cases programmable, hardware accelerators implementing functions less suited to software, such as signal down-conversion and advanced error correction, and are themselves re-used between standards.

The Ensigma Series4 family of RPUs provides a universal and scalable solution for integrating global connectivity and broadcast communications capabilities into SoCs. By combining the latest software programmable radio techniques with an advanced 4th generation multi-processor architecture, a wide range of communications standards are fully supported, including 802.11 based Wi-Fi standards, major broadcast TV receiver standards and major digital and FM broadcast radio standards.

The flexible hardware architecture of Ensigma Series4 RPUs means that the engine can be easily scaled to address everything from the smallest most cost-sensitive embedded connected processors to the most advanced connected smart TVs or tablets targeting global markets.
