Toni_McConnel-November 27, 2013

Imagination Technologies has announced IP that combines Wi-Fi, Bluetooth 4.0 and FM receiver in one configurable solution - the world's first, according to the company. With this combination of technologies, a new family of Ensigma Series4 ‘Explorer’ radio processor unit (RPU) cores provides a range of solutions for integration onto Systems-on-Chips (SoCs) targeting next-generation mobile, wearables, IoT and other connected products.

The new IP is available in configurable cores including:

  • C4531: Wi-Fi 802.11ac 2x2 + Bluetooth 4.0 + FM for products including tablets, ultrabooks, gaming consoles, smart TVs and more
  • C4521: Wi-Fi 802.11ac 1x1 + Bluetooth 4.0 + FM for devices including smartphones and tablets
  • C4511: Wi-Fi 802.11n 1x1 + Bluetooth + FM for products such as mobile handsets and wearables

The new Ensigma combo IP cores incorporate advanced algorithms and production-ready implementations of all supported standards to deliver better data throughput, sensitivity, and other key performance metrics, while minimizing host processing and power requirements.


Coexistence algorithms feature:
  • Advanced scheduling algorithms based on Bluetooth TX/RX cycle prediction
  • Coexistence-aware Carrier Sense, Packet Sync and Transmission
  • Efficient baseband/MAC level information sharing to track frequency and signal threshold adaptation
  • Multiple packet priorities for QoS across Bluetooth and Wi-Fi
  • Optional shared antenna
  • Support for standard 2, 3, 4 wire interface

Features include:
  • Unified memory architecture for the lowest possible silicon footprint
  • Maximum use of unified system memory, minimizing on-chip RPU memory demands for data and program storage
  • Removal of interface bottlenecks and processing requirements for USB/SDIO
  • Reduction of off-chip communication and external I/Os for increased power savings
  • Better host power management for reduced overall system power consumption
