Supercharging Agentic AI: How Leo X-Series Smart Memory Controllers Accelerate Inference With KV Cache Offload

In the early days of chat-based LLMs, the memory wall was driven by linear context growth. For each individual inference workload, expanding context length pushed available memory demand beyond capacity.But we are now in the agentic era. Agentic workloads operate on dynamic loops: They generate reasoning tokens, call external tools and APIs, parse returned data, and append state updates… Read more

The Ecosystem of Optical Fiber-to-Chip Connectors: Building Blocks of NPO and CPO for Scale-Up AI

We’ve been framing the increasing adoption of optical connectivity for scale-up applications with a clear organizing principle: Copper where you can, optics where you must. At today’s per-lane signaling rates in rack-scale AI fabrics, “must” is moving inside the rack. The reach and loss budgets available to passive copper compress with every protocol generation, and a growing number of… Read more

Seven Years Later: 200G Ethernet Retimers vs. Redrivers

Seven years ago, I wrote about the eye-popping difference between retimers and redrivers. The central point was that a redriver boosts an impaired signal, while a retimer recovers the data, extracts the embedded clock, and retransmits a fresh copy of the data on a clean clock. That distinction is still accurate and directly influences design decisions; but it’s not the only factor!On… Read more
