Sweeping Changes For Leading-Edge Chip Architectures
By Ed Sperling - 08 Sep, 2023 - Comments: 0

Chipmakers are utilizing both evolutionary and revolutionary technologies to achieve orders of magnitude improvements in performance at the same or lower power, signaling a fundamental shift from manufacturing-driven designs to those driven by semiconductor architects. In the past, most chips contained one or two leading-edge technologies, mostly to keep pace with the expected improvements i... » read more

Preparing For Commercial Chiplets

Processor Tradeoffs For AI Workloads
By Ann Mutschler - 10 Aug, 2023 - Comments: 0

AI is forcing fundamental shifts in chips used in data centers and in the tools used to design them, but it also is creating gaps between the speed at which that technology advances and the demands from customers. These shifts started gradually, but they have accelerated and multiplied over the past year with the rollout of ChatGPT and other large language models. There is suddenly much more... » read more

Generative AI Training With HBM3 Memory
By Frank Ferro - 20 Jul, 2023 - Comments: 0

One of the biggest, most talked about application drivers of hardware requirements today is the rise of Large Language Models (LLMs) and the generative AI which they make possible.  The most well-known example of generative AI right now is, of course, ChatGPT. ChatGPT’s large language model for GPT-3 utilizes 175 billion parameters. Fourth generation GPT-4 will reportedly boost the number of... » read more

Server Design With Pin-Efficient CXL Interface (Georgia Tech)
By Technical Paper Link - 10 May, 2023 - Comments: 0

A new technical paper titled "A Case for CXL-Centric Server Processors" was written by researchers at Georgia Tech. Abstract: "The memory system is a major performance determinant for server processors. Ever-growing core counts and datasets demand higher bandwidth and capacity as well as lower latency from the memory system. To keep up with growing demands, DDR--the dominant processor inter... » read more

Pinpointing Timing Delays Can Improve Chip Reliability
By Anne Meixner - 09 May, 2023 - Comments: 0

Growing pressure to improve IC reliability in safety- and mission-critical applications is fueling demand for custom automated test pattern generation (ATPG) to detect small timing delays, and for chip telemetry circuits that can assess timing margin over a chip's lifetime. Knowing the timing margin in signal paths has become an essential component in that reliability. Timing relationships a... » read more

A new technical paper titled "Automatic Creation of High-bandwidth Memory Architectures from Domain-specific Languages: The Case of Computational Fluid Dynamics" was published by researchers at Politecnico di Milano and TU Dresden. The paper states "In this article, we propose an automated tool flow from a domain-specific language for tensor expressions to generate massively parallel acceler... » read more

Tech Forecast: Fab Processes To Watch Through 2040
By Laura Peters - 16 Mar, 2023 - Comments: 0

The massive proliferation of semiconductors in more markets, and more applications within those markets, is expected to propel the industry to more than $1 trillion by 2030. But over the next 17 years, semiconductors will reach well beyond the numbers, changing the way people work, how they communicate, and how they measure and monitor their health and well-being. Chips will be the enabling ... » read more

Will AI Take My Job?
By Brian Bailey - 23 Feb, 2023 - Comments: 0

Everyone is talking about ChatGPT these days, and I am sure we will be comparing it with Google's new offering before long. I thought it was time that I gave it a quick spin, and since I am preparing to moderate a webinar about chiplets as I write this, I decided it was a good example of a fairly new field and would be a good test. I started by asking, "What are semiconductor chiplets, what ... » read more
