AI DSA Processor - 9-Stage Pipeline, Dual-issue

NI900 is a DSA processor based on 900 Series.

Overview

NI900 is a DSA processor based on 900 Series. NI900 is optimized with features specifically targeting AI applications.

Key features

  • Base Processor:
    Can be configured into any RV32 or RV64 processor ---N900/U900/NX900/UX900.
  • RVV1.0 VPU:
    Support VPU based on RISC-V V Extension (RVV1.0 Vector ISA), with 512-bit to 1024-bit VLEN configurable.
    • Lite-VPU: VPU can be configured to Lite-VPU, supporting frequently used embedded AI vector instructions and data types to save VPU area.
    • Shared VPU across Multiple Cores: Multiple cores within one cluster can share one VPU while keeping software consistent in a SMP architecture to save area.
  • NPU Accelerator:
    Can be tightly coupled with CPU through NI900's IOCP(IO Coherent Port) to maintain cache coherence with CPU.
  • User Defined Instruction Interface:
    Users can add customized scalar/vector instructions through Nuclei NICE interface, maintaining coherency with main CPU core.

RISC-V Based TinyML Accelerator for Depthwise Separable Convolutions in Edge AI

While lightweight architectures like MobileNetV2 employ Depthwise Separable Convolutions (DSC) to reduce computational complexity, their multi-stage design introduces a critical performance bottleneck inherent to layer-by-layer execution: the high energy and latency cost of transferring intermediate feature maps to either large on-chip buffers or off-chip DRAM. To address this memory wall, this paper introduces a novel hardware accelerator architecture that utilizes a fused pixel-wise dataflow.

Accelerating Your Development: Simplify SoC I/O with a Single Multi-Protocol SerDes IP

Enter the Multi-Protocol SerDes (Serializer/Deserializer)—a flexible, reusable IP block that allows a single PHY to support multiple serial communication protocols, such as PCIe, SATA, Ethernet, USB, and more. This approach enables SoC vendors to meet diverse customer requirements and application needs without redesigning I/O for each target market.
