Hsinchu, Taiwan, January 8, 2024 (Globe Newswire) — Andes Technology (TWSE: 6533) is a leading supplier of 32/64-bit, high-performance, low-power RISC-V processor cores and a founding company. Premier member RISC-V International and Spacetouch Technology, a high-tech company specializing in smart home, traditional home appliances, and consumer electronics, today jointly announced that the AndesCore™ D25F has been selected as the edge-side audio processor for the SPV60 series. I announced something. Fully integrates traditional and intelligent audio, introducing a new generation of on-device AI audio processors.
Andes Technology’s D25F processor is based on the AndeStar™ V5 architecture and is a 32-bit RISC-V CPU IP core with P extensions (DSP/SIMD extensions, draft version). By combining RISC-V DSP/SIMD ISA compilers, DSP libraries, and emulators with the highly optimized AndeSoft™ NN library, customers can efficiently accelerate AI application computing. Additionally, the D25F has many optional features, including instruction and data cache, low-latency local memory, and ECC for memory protection. The D25F can be configured as an AXI 64-bit or AHB 64/32-bit bus interface, and also has a port that allows direct external access to local memory. It can also be configured with a Platform Level Interrupt Controller (PLIC) that supports over 1,000 interrupt sources and provides rapid interrupt response, prioritization, and preemption. Additionally, Andes Custom Extension™ (ACE) provides additional flexibility through customized special purpose instructions. Integrating this rich set of features and configuration options, the D25F delivers superior efficiency and industry-leading performance, making it the first and perhaps most popular DSP-enabled RISC-V core in the embedded controller market.
At the same time, the new generation SPV60 series edge-side AI audio processor chip launched by Spacetouch adopts CPU + NPU + uDSP heterogeneous multi-core architecture, which combines different types of processors to efficiently perform various tasks, especially in the music field. will be processed accordingly. Audio processing. This heterogeneous multi-core architecture design significantly improves the AI audio processor chip. The SPV60 series on-device AI audio processor integrates the Andes D25F core with Spacetouch’s newly developed uDSP and AI NPU (neural network processor). Among them, the D25F CPU has a maximum frequency of over 400MHz and can handle general-purpose computing tasks. The NPU’s computational power reaches 100GOPs and is specially optimized for neural network computing. The uDSP core focuses on digital signal processing with special parallel acceleration according to known requirements and algorithm accumulation. Together, these features improve audio processing performance and efficiency. The chip also includes a high-performance audio AD (analog-to-digital) converter with over 105dB dynamic range and less than -95dB THD+N. DA (digital to analog) converter with over 105dB dynamic range and <-90dB THD+N. It also features a 0V direct drive headphone amplifier module with semi-professional performance. This chip comes with rich USB2.0, SD, SPI, UART, I2C, I2S and other peripheral interfaces, and supports AI noise reduction, AI echo cancellation, AI acoustic noise suppression, voice recognition and other algorithms. We support this. Spacetouch's edge-side AI audio processor chip focuses not only on superior performance but also on low power consumption. This is critical for area-sensitive use cases in embedded systems and mobile devices, as it allows for high performance while extending device battery life. Spacetouch provides professional development support, including tools and reference designs, to enable the SPV60 series chips to be widely deployed in intelligent voice, smart headphones, professional audio, and other related fields. The chip is already in mass production.
“Thanks to Spacetouch’s long-standing cooperation with Andes Technology, our SoC is equipped with an AndesCore™ processor and delivers powerful performance with multiple optional features,” said Hu Yingzhe, CEO of Spacetouch. “The combination of the D25F RISC-V processor and Spacetouch’s heterogeneous multi-core AI audio processor IC brings further innovation and possibilities to the fields of audio processing, embedded systems, and mobile devices.” With the processor IP and technical support provided by Andes Technology, both companies have laid a good foundation for a more successful cooperation in the future. “
“Andes’ D25F with DSP/SIMD enhancements offers efficient performance and flexible configurations, making it an ideal choice for high-performance embedded controllers.” Frankwell, Chairman and CEO, Andes Technology Lin said, “We are very excited that Spacetouch has collaborated with Andes to launch this new generation of edge-side AI audio processor chips. They continue to work with us to develop successful products while at the same time They also provide us with valuable feedback on our processors and development tools. We are confident that Spacetouch will be competitive with more AndesCore™ embedded products in the smart home, traditional appliances, and consumer electronics fields. We look forward to bringing this solution to market.”
