On-Chip Interconnect Control for Multicast Write Port Bottlenecks

The patent segments the write port resource allocation by introducing separate control information for each destination device. Instead of forcing all destinations to share a single write port, the system divides the control mechanism so that each destination device can be assigned its own write port through individualized control information from the source device, thereby eliminating the bottleneck of unified write port usage.

The patent implements dynamic write port assignment where the source device can flexibly select and assign different write ports to different destination devices based on real-time port availability. This dynamic allocation allows the system to adapt to changing conditions and maximize write port utilization, rather than being constrained by a static unified write port requirement.

The patent segments the control mechanism by providing separate control information for each destination device. This allows the source device to independently specify different write port identifiers for different destinations, breaking the constraint of unified write port usage and enabling each destination to utilize appropriate write ports based on their availability and requirements.

The patent applies local quality by allowing different write port assignments for different destination devices. Each destination device can be assigned a write port that is locally optimal for its specific situation, rather than being forced to use a globally unified write port. This localized optimization improves overall system adaptability and write port utilization.
