StarLink-500
StarLink-500 is StarFive's first self-developed interconnect fabric IP with cache coherence support, supporting the construction of multi-cores and SoC to provide cache coherence NoC: connecting multiple CPU clusters, IO devices, and DDR, and maintaining cache coherence within the SoC.
Feature
High Performance:
- Provides Last Level Cache (LLC), offers Snoop Filter, and improves the efficiency of coherence maintenance modules, and memory hierarchy performance.
Efficient Data Exchange
- Supports CPU and IO device sharing of LLC, simplifying CPU and IO data exchange and improving performance.
Low Power Consumption
- Supports LLC way shutdown, cache retention, and other low-power technologies.
High Reliability
- Snoop Filter and LLC support SEC-DED (Single Error Correction Double Error Detection).
Control Interface Support (CFG & MMIO)
- CPU configuration of IO devices and on-chip SRAM reading; IO device access and configuration of on-chip interconnect coherence.
