Time-Track Technology releases RISC-V-based DSA architecture end-side intelligent voice chip AT820

Recently, at the second Dishui Lake RISC-V Forum, Yu Xin, president of TimeQing Technology, introduced the company's newly launched RISC-V instruction architecture chip AT820.

Yu Xin said that as one of the earliest teams in China to participate in RISC-V research and development, Time-Track Technology has also grown with the development of the RISC-V industry. Yu Xin said that with the advent of the 5G and IoT era, the total capacity of the chip market is large, but due to the existence of fragmentation, it is difficult to have a universal solution. Time-Track Technology hopes to find common points in different scenarios to cut in.

There are three understandings here. First, the algorithm + chip forms a complete solution for application scenarios. Second, customized chips can fully meet the needs of differentiated scenarios. Third, there needs to be a large enough market to meet the return on investment. Based on these three points, ShiQing Technology believes that the processor/chip of the DSA architecture is one of the effective ways to solve fragmentation.

Time-Track Technology also provides three main product lines to meet the needs of different applications and operators, including master control processors, DSP processors and neural network processors.

AT820 chip

AT820 is a highly integrated, cost-effective, low-power end-side intelligent chip. It is specially optimized for dual-microphone scenarios with software and hardware. It can be applied to intelligent voice interaction, voice front-end processing, intelligent control, noise reduction and other scenarios. The application scenarios include conference treasures, intercoms, microphones, etc.

The built-in self-developed 300MHz 32-bit RISC-V core can support FP16 and FP32 floating-point operations. The self-developed TimesFlow algorithm deployment tool is integrated to support various mainstream network models, various quantization methods and options, including symmetric, asymmetric, online and offline quantization, various mixed precision quantization, etc.
