Meeting 112 SerDes Based System Design Challenges


The need for higher bandwidth networking equipment as well as connectivity in the cloud and hyperscale data centers is driving the switch technology transition from 25Tb/s (terabytes) to 51Tb/s and soon to 100Tb/s. The industry has chosen Ethernet to drive the switch market, using 112G SerDes or PHY technology today and 224G SerDes in the future. This article describes how designers can overcom... » read more

Electronics And Sustainability: Can Smart Engineering Save The Planet?


We just celebrated Earth Day 2022 with great fanfare. In discussions with my favorite Gen Z family member, I sense genuine concerns that sustainability goals seem like a tall order. Let’s review the contributions the electronics industry can make to sustainability. First, defining sustainability seems to lead to three main pillars—environmental, social, and economic sustainability. I fou... » read more

High-Performance SerDes Enable The 5G Wireless Edge


Investment at the core of the global internet is red hot. The number of hyperscale data centers jumped to 700 worldwide at the end of 2021, and with more than 300 in the pipeline, should rise to over 1000 by 20241. In the span of five years, total hyperscale data centers will have doubled. And as the raw number shoots up, more powerful compute and networking hardware is rapidly being deployed, ... » read more

Silicon Lifecycle Management’s Growing Impact On IC Reliability


Experts at the Table: Semiconductor Engineering sat down to talk about silicon lifecycle management, how it's expanding and changing, and where the problems are, with Prashant Goteti, principal engineer at Intel; Rob Aitken, R&D fellow at Arm; Zoe Conroy, principal hardware engineer at Cisco; Subhasish Mitra, professor of electrical engineering and computer science at Stanford University; a... » read more

Power Now First-Order Concern In More Markets


Concerns about energy and power efficiency are becoming as important as performance in markets where traditionally there has been a significant gap, setting the stage for significant shifts in both chip architectures and in how those ICs are designed in the first place. This shift can be seen in a growing number of applications and vertical segments. It includes mobile devices, where batteri... » read more

Why Comparing Processors Is So Difficult


Every new processor claims to be the fastest, the cheapest, or the most power frugal, but how those claims are measured and the supporting information can range from very useful to irrelevant. The chip industry is struggling far more than in the past to provide informative metrics. Twenty years ago, it was relatively easy to measure processor performance. It was a combination of the rate at ... » read more

Assuring Reliable Processor Performance At Scale


In today’s data center environment, resilience is key. Cloud providers are built on as-a-service business models, where uptime is critical to ensure their customers’ business continuity. Reputation and competitiveness require service at extremely high performance, low power, and increasing functionality, with zero tolerance for unplanned downtime or errors. If you’re a hyperscaler, o... » read more

Data Center Architectures In Flux


Data center architectures are becoming increasingly customized and heterogeneous, shifting from processors made by a single vendor to a mix of processors and accelerators made by multiple vendors — including system companies' own design teams. Hyperscaler data centers have been migrating toward increasingly heterogeneous architectures for the past half decade or so, spurred by the rising c... » read more

Thermal Management Implications For Heterogeneous Integrated Packaging


As the semiconductor industry reaches lower process nodes, silicon designers struggle to have Moore's Law produce the results achieved in earlier generations. Increasing the die size in a monolithic system on chip (SoC) designs is no longer economically viable. The breakdown of monolithic SoCs into specialized chips, referred to as chiplets, presents significant benefits in terms of cost, yield... » read more

Why Data Center Power Will Never Come Down


Data centers have become significant consumers of energy. In order to deal with the proliferation of data centers and the servers within them, there is a big push to reduce the energy consumption of all data center components. With all that effort, will data center power really come down? The answer is no, despite huge improvements in energy efficiency. “Keeping data center power consum... » read more
