An Introduction to RISC-V Vector Programming with C Intrinsic


Speaker: Chih-Mao Chen, Advanced Engineer | English

The "V" ISA extension for vector processing has been proposed to RISC-V to exploit data parallelism in domains such as machine learning and high-performance computing applications. In contrast to traditional SIMD processors with fixed-length vectors, the RISC-V vector extension defines a vector-length agnostic architecture where work is vectorized independently of a vector length that can be discovered at run-time. This is a departure from existing SIMD frameworks where the vector lengths are known statically, and a new intrinsic interface that takes advantage of scalable nature of RISC-V vectors is being developed by the community. This talk will provide an overview of the vector extension and how to program the vector processor, using Andes NX27V as an example, with C-level scalable vector types and intrinsic functions, as well as design choices and future evolution of the API.

Andes Infuses into AI: High-Efficiency and High-Flexibility Processor IPs+NN SDK for AI


Speaker: John Min, Director of NA Field Application Engineering

To fulfill the diversity of AI applications (e.g., keyword spotting, object detection, etc.) in different environments including edge and cloud, Andes provides you with different choices to fit your AI targets with various requirements (computing power, power consumption, SRAM and code size). In this talk, Andes will introduce how RISC-V Packed-SIMD/DSP processors and RISC-V vector processors provide the high computing efficiency and flexibilities. Further with Andes NN SDK, it will be easy to integrate your AI applications to the shorter time-to-market, and achieve the outstanding utilization of hardware capabilities.

RISC-V Vector Extension and NX27V, the First Commercial RISC-V Vector Processor IP ​


Speaker: John Min, Director of NA Field Application Engineering

The applications of AI, AR/VR, computer vision, cryptography, and multimedia require high-speed processing of large volumes of data. A RISC-V processor with the powerful RISC-V Vector (RVV) extension instruction set and parallel execution capability can significantly accelerate the performance of those applications.

AndesCore™ NX27V is the first commercial RISC-V processor to support RVV scalable vector instruction set, designed from ground up to be a Cray-like full vector computation machine. The NX27V provides a Vector Register File (VRF) with each register as large as 512 bits. Its supports RVV standard data types such as integer, fixed point, and floating point as well as Andes-enhanced data types optimized for AI representations. The NX27V contains a scalar unit and a Vector Processing Unit (VPU). The VPU has multiple functional units, operating on inputs of up to 512 bits each cycle in parallel to sustain the computational throughput needed in diversified applications. For software development support, in addition to the compilation tools and the performance simulator, Andes also provides a powerful visualization tool for the NX27V to help analyze and optimize the performance of critical computation kernels.

Andes High Memory Efficiency 27 Series and Superscalar 45 Series CPU IP Cores​


Speaker: KY Hsieh, Senior Technical Manager

Inheriting technologies from its successful 25-series, AndesCore™ 27-series is Andes Technology's second-generation RISC-V CPU IP solution. The recently released 32-bit A27 and 64-bit AX27 offer over 2 times higher bandwidth and deliver lower latency with its MemBoost technology, it is well suitable for memory-intensive applications, such as those run on Linux operating system.

The new 32/64-bit 45-series is an 8-stage in-order superscalar processor benefits from Andes’ proven 25-series cores, and compliant with the latest RISC-V specifications. It can issue two instructions per cycle and therefore significantly increases its performance. The superior pipelining results in world-class 5.4 Coremark/MHz, and can run up to 1.2GHz at 28nm in the worst case. The 45-series cores are ideal for embedded applications where response time and determinism are critical, such as 5G, AI, AR/VR, ADAS, IP surveillance, networking, storage, and V2X.

TWS (True Wireless Stereo) Solution Using Andes D25+ACE ​


Speaker: Tung Wei, Advanced Engineer

Andes D25, a power-efficient RISC-V CPU that supports P-extension for rich SIMD/DSP computation, is widely used in audio, voice, image and DSP applications. In addition, D25 is equipped with the powerful ACE (Andes Custom Extension™), which, by writing simple scripts and concise RTL codes, allows designers to new instructions to speed up critical functions and reduce power consumption at the same time.

TWS (True Wireless Stereo), a Bluetooth 5.0 technology, is expected to have continuous growth following leading vendors’ great success in their hot-selling TWS earphones. The challenge for SoC designers is to perform many complex computations fast and with low power consumption. In this webinar, we will introduce a unique solution for TWS based on D25 plus ACE acceleration. With the advantages of high flexibility, easy-to-integrate and low power, it perfectly addresses the requirements of TWS. It is the TWS solution you are looking for!
