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
