DesignWare IP Subsystem Integrates New Audio/Voice/Speech and I3C Hardware and Software to Address Expanding Processing Requirements of Secure, Multi-Sensor SoCs

Highlights:

• ARC Data Fusion IP Subsystem includes choice of ARC EM DSP processor (EM5D, EM7D, EM9D or EM11D), tightly coupled memory, peripherals and hardware accelerators that reduce SoC area and power
• ARC EM DSP processors provide combination of high-efficiency control and signal processing to minimize energy consumption for always-on IoT functions
• Audio software library, tightly coupled pulse density modulation (PDM) and I²S peripherals simplify the integration of voice and audio interfaces increasingly common in IoT devices
• Integrated hardware extensions accelerate cryptography algorithms such as AES, SHA and RSA/ECC with minimal impact to silicon area
• MIPI I3C option enables higher performance sensor interfaces for portable devices

Synopsys, Inc. (Nasdaq: SNPS) today announced it has enhanced its  DesignWare^® ARC^® Data Fusion IP Subsystem with a new suite of tightly coupled interface peripherals including pulse density modulation (PDM), I²S and I3C, as well as an audio processing software library to speed application software development. The Data Fusion IP Subsystem is an integrated, pre-verified hardware and software IP product optimized for use in devices requiring minimal energy consumption. The latest enhancements to the subsystem simplify the implementation of voice and speech functionality in a range of applications such as far-field voice user interfaces and hands-free voice commands. In addition, the standards-compliant MIPI I3C controller enables high data rate transmission for the integration of multiple sensors in a system-on-chip (SoC). The DesignWare ARC Data Fusion IP Subsystem offers the choice of an ARC EM DSP processor (EM5D, EM7D, EM9D or EM11D) and delivers the efficient real-time control and DSP performance required for ultra-low-power IoT applications requiring sensor fusion, audio playback, voice detection and speech recognition.   

"The audio, voice and speech requirements of IoT devices demand excellent DSP performance within tight area and power budgets," said Dr. Alexander Goldin, CEO at Alango Technologies. "The combination of Synopsys' power-efficient ARC Data Fusion IP Subsystem with our voice enhancement software provides developers with an excellent solution that can be rapidly deployed into SoCs for always-on applications."

The ARC Data Fusion IP Subsystem processes data from digital and analog sensors with minimal energy consumption, offloading the host processor and enabling more efficient data processing. The fully configurable subsystem, with its choice of power-efficient ARC EM DSP processors, delivers a 2x performance boost for typical signal processing functions such as filtering, matrix operations and complex math compared to other available processors. In addition, the subsystem significantly reduces frequency and memory requirements to run audio codecs and speech/voice communication software, saving energy and costly die area.

The ARC Data Fusion IP Subsystem also includes an audio processing software library of common functions, including gain control, mixer and sample rate converter. Tightly coupled PDM and I²S peripherals simplify integration of external audio devices such as MEMS microphones used for far-field voice user interfaces and hands-free voice commands. The hardware PDM interface implementation is 6x more energy efficient than the equivalent software implementation, with minimal gate count impact. An optional MIPI I3C master/slave peripheral, compliant with the MIPI Camera Control Interface (CCI), I2C and I3C specifications, provides a high-performance sensor interface. It is equivalent to SPI performance and backward compatible with I2C interfaces. The integrated I3C peripheral and included software driver simplify mobile sensor integration and provide power and area savings over discrete implementations.

In addition, the separately licensable ARC CryptoPack option provides special instructions that accelerate common cryptographic algorithms such as AES, SHA-256, RSA and ECC (elliptic curve cryptography) to deliver up to 7x greater performance compared to software-only implementations. Synopsys' embARC Open Software Platform gives software developers online access to a comprehensive suite of free and open-source software that accelerates code development for the IP subsystem.

"The proliferation of voice-enabled IoT devices requires designers to incorporate more audio capabilities into their SoCs while maintaining performance efficiency and minimal power consumption," said John Koeter, vice president of marketing for IP at Synopsys. "With the latest enhancements to the silicon-proven DesignWare ARC Data Fusion IP Subsystem, designers can efficiently integrate the voice and speech functionality required for multi-sensor IoT designs and accelerate their project schedule."
