Low Power 32-bit DSP Architecture Framework for Advanced Audio and Voice Applications

Ceva-TeakLite-4 is a low-power, native 32-bit, variable 10-stage pipeline, fixed-point DSP architecture framework. The Ceva-TeakLite-4 is a fully synthesizable, process-independent design that allows the SoC designer to select the optimal implementation in terms of silicon area, power consumption, and operating frequency.

Ranging from dual 16x16-bit MAC and single 32x32-bit MAC to quad 16x16-bit MAC and dual 32x32-bit MAC, The Ceva-TeakLite-4 DSP family includes the deeply embedded Ceva-TL410 and Ceva-TL411, along with the cache enabled Ceva-TL420 and Ceva-TL421 DSP cores, that are all fully compatible. The four cores enable much needed scalability and are also backward compatible with previous generation cores of the Ceva-TeakLite family.

Thanks to its scalability, the Ceva-TeakLite-4 DSP family is efficiently handling most demanding audio, voice, sensor fusion and wireless connectivity use-cases, whether targeting ultra-low-power always-on voice control, advanced multi-microphone noise reduction and voice processing, VoLTE or high-performance multichannel audio processing and post-processing. Ceva-TeakLite-4 cores are adopted by mobile, home, IoT and automotive chip vendors, for use in the smallest, lowest-power audio CODEC, audio DSP, voice activation and sensor hub chips, through Baseband, Application Processors and connectivity chips, and up to high-end multi-channel audio such as wireless speakers, digital televisions (DTVs), set-top boxes (STBs), game consoles, and more.

Combined with the Ceva-Bluetooth hardware and software, the Ceva-TeakLite-4 further enables a wide range of wireless applications from Bluetooth Smart (a.k.a. single mode Bluetooth Low Energy or BLE) to Bluetooth Smart Ready (a.k.a. dual mode Bluetooth Low Energy) and wireless audio.
