Chiplet-based processors have become the dominant architecture for modern servers, partitioning functionality across compute chiplets and a centralized I/O chiplet. While this design improves scalability, it introduces a new bottleneck— the I/O Chiplet Wall—where off-chip memory and device requests contend along a shar...
