Open Platform for Communication-AI Convergence Fusion

ACE-Echo

Communication.
Intelligence.
One architecture.

An open development platform built on Venus, our programmable RISC-V processor for communication–AI convergence. Explore the architecture. Build applications for our hardware. Shape what comes next.

The Echo ecosystem

  • Communication & AI operators for FFT, Decoder, Conv2D/3D, GELU/SiLU and more
  • An integrated development workflow with external compiler tools
  • Gem5 simulation for Venus application development and approximate performance evaluation
  • Application demonstrations and research directions: 5G/LTE, AI-based channel estimation, GNSS, LoRa and more
  • An initial Agent-assisted development framework in 1.0

An idea.
Now in your hands.

Our first-generation chip has taped out
and achieved first light.

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 such as the vector engine
  • Composed of Venus Tile, Venus Scheduler, and Venus DFE
  • Research directions spanning wireless baseband, edge AI and communication–AI integration

For details, see A Hierarchical Dataflow-Driven Heterogeneous Architecture for Wireless Baseband Processing.
