Imagination delivers radio processor unit IP cores

Available now to developers from Imagination Technologies . is the Ensigma Series4 radio processor unit (RPU) IP core family which takes a different approach to supporting such demanding wireless protocols as 802.11ac 2×2 MIMO and DVB-T2.

According to Tony King-Smith, EVP marketing, Imagination, by adding new highly-specialized data processors combined with a significantly upgraded internal data fabric, the Series4 RPUs are designed for a wide range of wireless applications, from connected home multimedia to advanced continuous data roaming.

The Ensigma 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 baseband 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.

By combining a range of various software programmable radio techniques with a fourth generation multi-processor architecture, he said the new family can support a number of communications standards including:

* All 802.11 based Wi-Fi standards up to full 802.11ac 2×2 MIMO and 802.11n with 4×4 MIMO as well as Bluetooth,
* All major broadcast TV receiver standards, and
* All 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<” he said.

The Series4 family of Ensigma RPUs comes in four ranges: C4xxx cores for supporting various connectivity standards, T4xxx cores for TV standards, R4xxx cores for broadcast radio standards, as well as U4xxx cores which are universal variants supporting all standards.

King-Smith said this approach to supporting multiple standards on a single engine, solves the ever-growing challenge of proliferating broadcast and/or connectivity standards.

He said they also address the issue of ‘future-proof’ integration of all communications requirements onto the latest SoCs, while achieving the lowest system cost, highest performance and lowest power consumption under all operating conditions. A high level of programmability means the same SoC can be used across multiple markets and product generations with only minimal changes.

Ensigma RPUs support all key standards for connectivity including 802.11abg, 802.11n with up to 4×4 MIMO, 802.11ac with up to 2×2 MIMO, as well as Bluetooth. They also enable global TV products supporting DVB-T2, DVB-T, ISDB-T, ATSC, GB20600-2006 (CTTB), DVB-S2, DVB-S, ISDB-S, DVB-C, J.83B, ISDB-C; analogue TV; mobile TV including T-DMB, 1-Seg ISDB-T; and broadcast radio standards including DAB/DAB+, HD Radio, 3-seg ISDB-T, ISDB-Tmm and FM.
