Echo — The Open Platform for Communication–AI Convergence Fusion
🌍 What Is Echo?
Echo is an open-source development platform built on Venus, our RISC-V processor designed for communication-AI fusion. Echo empowers developers to build, test, and deploy next-generation applications where signal processing meets intelligent computation.
Echo includes:
- Communication & AI operators for FFT, Decoder, Conv2D/3D, GELU/SiLU and more
- A full toolchain: compiler, debugger and hardware simulator
- Functional & Performance Simulator: Simulates Venus workloads and output Latency & throughput estimation
- Real-world application demos (5G/LTE, AI-Based Channel Estimation, GNSS, LORA, etc.)
- Comprehensive documentation & tutorials
🔋 Powered by AURA Architecture & Venus Chip
AURA: AI Unified Radio Architecture
AURA is the foundational computing architecture behind Echo. It is designed for tight integration of perception, communication, and computation, optimized for edge and low-latency scenarios.It is composed of Venus Language, Zoozve Compiler, and Mathematic Libraries. ( If you want to learn more about compilers, you can see Zoozve: A Strip-Mining-Free RISC-V Vector Extension with Arbitrary Register Grouping Compilation Support (WIP) )

Venus: Our RISC-V Communication-AI Chip
Venus is a custom RISC-V processor based on the AURA architecture:
- Instruction set extensions for communication and neural workloads
- Built-in accelerators (vector engine, etc.)
- Composed of Venus Tile, Venus Scheduler, and Venus DFE ( For details, see A Hierarchical Dataflow-Driven Heterogeneous Architecture for Wireless Baseband Processing )

- Ideal for 5G/6G, GNSS, LoRa, edge AI, V2X, and more
