RISC-V embedded processing portfolio has new voice-control ASSP solution

06-04-2023 | Renesas | Semiconductors

Renesas Electronics Corporation has expanded its industry-leading RISC-V portfolio with the first RISC-V MCU developed for voice-controlled HMI systems. The new R9A06G150 32-bit ASSP, created in collaboration with RISC-V ecosystem partners, offers a complete, cost-effective, production-ready voice-control system solution that removes the necessity for RISC-V tools and upfront software investment.

Aimed at residential and commercial building automation, toys and healthcare devices, home appliances, the new ASSP supports multiple languages and user-defined keywords for voice-recognition operations. The basis of a turnkey voice-control solution, the device is pre-programmed using specialised application code produced by independent design houses with an ability to bring customer designs to volume production.

"Renesas continues to broaden our RISC-V MCU/MPU offering, in this case by delivering designers an innovative voice-command HMI with pre-developed software that shortens development time and time to market," said Roger Wendelken, senior vice president in Renesas' IoT and Infrastructure Business Unit. "Through close collaboration with the RISC-V partner ecosystem, this flexible, scalable ASSP solution allows customers interested in voice control to support different application classes on the same MCU hardware platform."

The new voice-control HMI ASSP is based on RISC-V processing IP from Andes Technology Corp, which included its AndesCore D25F CPU core based on the AndeStar V5 architecture. "We are excited to be part of Renesas' turnkey voice control solution," said Frankwell Lin, Andes' chairman and CEO. "The 32-bit AndesCore D25F was engineered to deliver high per-MHz performance in a small silicon footprint. Major mixed-signal ASSP developers such as Renesas can thus concentrate on their core engineering innovation and outsource non-critical elements of their design to CPU core suppliers such as Andes."
