All Silicon IP


Audio/Voice DSP reference design platform is developed based on the CEVA-TeakLite-4 DSP core and fabricated at SMIC s 55nmLP process, running up to 500MHz. The platform provides designers with a powerful means to add smart and connected capabilities to these devices, including always-on sensing, local processing and intelligence connectivity. The platform also provides real-time power measurement that allows developers to improve power consumption of system by optimizing their DSP software effectively. It provides a complete development and demo system integrating DSP and multiple peripherals & interfaces IP, and supports diverse wireless technologies including Bluetooth Smart and Smart Ready, Wi-Fi, ZigBee and GNSS. It can be adopted on mobile, wearable devices, wireless speaker, smart home, surveilance, automotives and so on.
