Optimized software enables low-power neural
network inferencing for advanced audio, voice and sensing
applications
Cadence Design Systems, Inc. (Nasdaq: CDNS) today announced that
software for Cadence® Tensilica® HiFi digital signal processors
(DSPs) has been optimized to efficiently execute TensorFlow Lite
for Microcontrollers, part of the TensorFlow end-to-end open-source
platform for machine learning (ML) from Google. The combination of
edge-based ML running on the ultra-low power cores supports the
increasing demand for pervasive intelligence in advanced audio,
voice and sensing applications. For more information on the

The HiFi DSPs are the first DSPs to support TensorFlow Lite for
Microcontrollers. With the addition of optimized software support
for TensorFlow Lite operators on the HiFi DSP cores, developers can
now take full advantage of the TensorFlow platform. This promotes
rapid development of edge applications that use artificial
intelligence (AI) and ML, removing the need for hand-coding the
neural networks and resulting in faster time to market and higher
performance.
Implementing AI at the edge, including devices that use voice
and audio as a user interface, requires running the inference model
on the device. This has many benefits:
- Eliminates the latency associated with sending data to a cloud
service and waiting for the response to be sent back to the
device
- Reduces power consumption associated with sending/receiving
large amounts of data across a network
- Maintains privacy and minimizes security issues since the data
never leaves the device
- Without cloud dependency, the device can be disconnected from
the network and still operate
“Voice and audio AI applications are now mainstream, as
voice-based user interfaces become more popular with consumers,”
said Ian Nappier, product manager at Google. “TensorFlow Lite’s
microcontroller software combined with optimized operators for the
HiFi DSP makes developing and deploying innovative neural nets on
low-power, memory-constrained audio DSPs easier than ever.”
“Our powerful crossover microcontroller, the i.MX RT600,
includes a 600MHz Tensilica HiFi 4 DSP that delivers 4.8GMACs of
performance,” explained Joe Yu, VP of microcontrollers at NXP®
Semiconductors. “This new MCU provides the optimal balance in power
and performance. The compute power makes the i.MX RT600 ideal for
our customers deploying voice, audio, and other neural
network-based applications at the edge. Supporting the popular,
end-to-end toolchain, TensorFlow, as well as other inferencing
technologies, on the HiFi DSP will enable ML developers to take
advantage of the compelling combination of compute and memory on
this chip.”
“Enabling ML at the edge saves power, protects privacy and
greatly reduces latency,” observed Yipeng Liu, director of
audio/voice IP at Cadence. “Tensilica HiFi DSPs are the most widely
licensed DSPs for audio, voice and AI speech. Support for
TensorFlow Lite for Microcontrollers enables our licensees to
innovate with ML applications like keyword detection, audio scene
detection, noise reduction and voice recognition, with the
assurance that they can run in an extremely low-power
footprint.”
Tensilica HiFi DSPs are part of the broad Cadence IP portfolio
and support Cadence’s Intelligent System Design™ strategy, enabling
pervasive intelligence.
