A fusion DSP for IoT
To be designed into SoCs for applications such as wearable activity monitoring, indoor navigation or context-aware sensor fusion, the scalable DSP is aimed at applications requiring merged controller plus DSP computation while running at ultra-low power.
Optional Instruction Set Architecture (ISA) extensions are included to accelerate multiple wireless protocols including Bluetooth Low Energy, Thread and Zigbee using IEEE 802.15.4, SmartGrid 802.15.4g, Wi-Fi 802.11n and 802.11ah, 2G and LTE Category 0 release 12 and 13, and global navigation satellite systems (GNSS).
The Tensilica Fusion DSP is claimed to use 25 percent less energy than the company’s previously released HiFi Mini DSP, based on running a power diagnostic derived from the Sensory Truly Handsfree always-on algorithm.
The DSP combines an enhanced 32-bit Xtensa control processor with market-leading base DSP features and flexible algorithm-specific acceleration for a fully programmable approach, supporting multiple existing and developing standards and customer algorithms. IoT device designers can configure just the options they need using the Xtensa Processor Generator to create an optimized Tensilica Fusion processor.
Configurable elements include a tightly integrated floating point, 1 to 4 MACs supporting real and complex operations, AES-128 encryption, a flexible memory architecture, MAC and PHY algorithm acceleration and audio/voice compatibility with the Tensilica HiFi architecture.
Designers benefit from a library of DSP functions and more than 150 audio/voice/fusion applications from over 70 partners.
