San Jose, Calif. - Cadence Design Systems, Inc. has introduced the new Cadence Tensilica Fusion digital signal processor (DSP) based on the Xtensa Customizable Processor. The Tensilica Fusion DSP uses 25 percent less energy, based on running a power diagnostic derived from the Sensory Truly Handsfree always-on algorithm when compared to the current low-power Cadence Tensilica HiFi Mini DSP, said the company.
The scalable DSP is suited for applications requiring merged controller plus DSP computation, ultra-low energy and a small footprint. It can be designed into systems on chip (SoCs) for wearable activity monitoring, indoor navigation, context-aware sensor fusion, secure local wireless connectivity, face trigger, voice trigger and voice recognition. 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 combines an enhanced 32-bit Xtensa control processor with flexible algorithm-specific acceleration for full programmability. It supports multiple existing and developing standards and customer algorithms. As an example, IoT device designers can configure just the options they need using the Xtensa Processor Generator to create an optimized Tensilica Fusion processor, said the company.
Tensilica Fusion DSP configurable elements include:
- Tightly integrated floating point
- 1-4 MACs supporting real and complex operations
- AES-128 encryption
- Flexible memory architecture
- MAC and PHY algorithm acceleration
- Audio/voice compatibility with the Tensilica HiFi architecture
The Tensilica Fusion DSP offers a library of DSP functions and more than 1540 audio/voice/fusion applications from more than 70 partners. The Tensilica partner ecosystem includes other applications software, emulation and probes, silicon and services.
