Co-Packaged Optics And The Evolution Of Switch/Optical Interconnects In Data Centers
By Synopsys - 27 Oct, 2021 - Comments: 0

Driven by a need to reduce power and increase bandwidth density in data center network switches and other devices, the data networking industry is moving toward adoption of co-packaged optics (CPO). This paper provides a brief overview of the history of copper and optical interconnects, the limitations of existing interconnect solutions, and the future of co-packaged optics, including the benef... » read more

Will Co-Packaged Optics Replace Pluggables?
By Bryon Moyer - 14 Oct, 2021 - Comments: 0

As optical connections work their way deeper into the data center, a debate is underway. Is it better to use pluggable optical modules or to embed lasers deep into advanced packages? There are issues of convenience, power, and reliability driving the discussion, and an eventual winner isn’t clear yet. “The industry is definitely embracing co-packaged optics,” said James Pond, principal... » read more

Servers And The Drive To DDR5
By Rambus - 13 Aug, 2021 - Comments: 0

This IDC Technology Spotlight Study, sponsored by Rambus, discusses server demands on DRAM and different workloads. DRAM must dynamically adjust to the needs of these disparate workloads. The history of dynamic random-access memory (DRAM) is characterized by the ability of the technology to adapt to the increasingly specialized real-time memory requirements of the applications that utilize it. ... » read more

Lowering Energy Per Bit
By Ann Mutschler - 12 Aug, 2021 - Comments: 0

Energy is emerging as a focal point in chip and system design, but solving energy-related issues needs to be dealt with on a much broader scale than design teams typically see. Energy is the amount of power consumed over a period of time to perform a given task, but reducing energy is a lot different than reducing power. It affects everything from operational costs and system performance to ... » read more

Sweeping Changes Ahead For Systems Design
By Ann Mutschler - 29 Jul, 2021 - Comments: 0

Data centers are undergoing a fundamental change, shifting from standard processing models to more data-centric approaches based upon customized hardware, less movement of data, and more pooling of resources. Driven by a flood of web searches, Bitcoin mining, video streaming, data centers are in a race to provide the most efficient and fastest processing possible. But because there are so ma... » read more

Cheng Wang, co-founder and senior vice president of software and engineering at Flex Logix, sat down with Semiconductor Engineering to explain the process of bringing an inferencing accelerator chip to market, from bring-up, programming and partitioning to tradeoffs involving speed and customization.   SE: Edge inferencing chips are just starting to come to market. What challenges di... » read more

CXL Memory Interconnect Initiative: Enabling A New Era of Data Center Architecture
By Rambus - 30 Jun, 2021 - Comments: 0

In response to an exponential growth in data, the industry is on the threshold of a groundbreaking architectural shift that will fundamentally change the performance, efficiency and cost of data centers around the globe. Server architecture, which has remained largely unchanged for decades, is taking a revolutionary step forward to address the growing demand for data and the voracious performan... » read more

Data Centers On Wheels
By Ann Mutschler - 28 Jun, 2021 - Comments: 2

Automotive architectures are evolving quickly from domain-based to zonal, leveraging the same kind of high-performance computing now found in data centers to make split-second decisions on the road. This is the third major shift in automotive architectures in the past five years, and it's one that centralizes processing using 7nm and 5nm technology, specialized accelerators, high-speed memor... » read more

Architectural Considerations For AI
By Brian Bailey - 24 Jun, 2021 - Comments: 2

Custom chips, labeled as artificial intelligence (AI) or machine learning (ML), are appearing on a weekly basis, each claiming to be 10X faster than existing devices or consume 1/10 the power. Whether that is enough to dethrone existing architectures, such as GPUs and FPGAs, or whether they will survive alongside those architectures isn't clear yet. The problem, or the opportunity, is that t... » read more

Shifting Toward Data-Driven Chip Architectures
By Ed Sperling and Ann Mutschler - 16 Jun, 2021 - Comments: 0

An explosion in data is forcing chipmakers to rethink where to process data, which are the best types of processors and memories for different types of data, and how to structure, partition and prioritize the movement of raw and processed data. New chips from systems companies such as Google, Facebook, Alibaba, and IBM all incorporate this approach. So do those developed by vendors like Appl... » read more
