High-scalable, high-performance Interconnect fabric IP with cache coherence support

StarNoC-700 is the vendor's self-developed high-scalable, high-performance interconnect fabric IP supporting cache coherence, enabling the construction of manycore SoC solution.

Providing NoC with cache coherence

• Connecting up to 256 CPU cores, IO devices, and DDR, while maintaining cache coherence within the SoC scope

High Performance:

• Providing a maximum of 512 MB Last Level Cache (LLC) with Snoop Filter, enhancing the efficiency of coherence maintenance modules and memory hierarchy performance.

High scalability

• Employing mesh NoC to enhance expandability, and a dedicated control NoC to support control command transmission

Low latency

• Adopting a semi-custom design approach to reduce NoC transmission latency.

Efficient data exchange

• Supporting CPU and IO devices to share the LLC, simplifying CPU and IO data exchange, and improving performance

Low power consumption

• Supporting low power consumption technologies such as LLC way shutdown and Architecture Clock Gating

High reliability

• Snoop Filter and LLC support ECC (SEC-DED, Single Error Correction Double Error Detection)

• High bandwidth, low power consumption, low latency
• Support Component Aggregation Layer (CAL)
• Topology: Mesh
• Support multiple I/O Coherent Master Nodes (CIO)
• Maximum node count: 12x12
• Single node supports 3-5 devices
• Configurable data path link width: 128/256/512b
