The High But Often Unnecessary Cost Of Coherence


Cache coherency, a common technique for improving performance in chips, is becoming less useful as general-purpose processors are supplemented with, and sometimes supplanted by, highly specialized accelerators and other processing elements. While cache coherency won't disappear anytime soon, it is increasingly being viewed as a luxury necessary to preserve a long-standing programming paradig... » read more

The Return Of DAC In-Person


Apart from masked faces everywhere, you could be excused for not knowing that there was a pandemic going on. Sure, the numbers were down, the show floor was smaller, and most of the parties didn't happen, but everyone was so happy to be able to bump elbows with their colleagues. Buttons were available for attendees to show the level of comfort they had with various types of greetings, from "... » read more

What’s Next For Transistors And Chiplets


Sri Samavedam, senior vice president of CMOS Technologies at Imec, sat down with Semiconductor Engineering to talk about finFET scaling, gate-all-around transistors, interconnects, packaging, chiplets and 3D SoCs. What follows are excerpts of that discussion. SE: The semiconductor technology roadmap is moving in several different directions. We have traditional logic scaling, but packaging i... » read more

New Power, Performance Options At The Edge


Increasing compute intelligence at the edge is forcing chip architects to rethink how computing gets partitioned and prioritized, and what kinds of processing elements and memory configurations work best for a particular application. Sending raw data to the cloud for processing is both time- and resource-intensive, and it's often unnecessary because most of the data collected by a growing nu... » read more

Bumps Vs. Hybrid Bonding For Advanced Packaging


Advanced packaging continues to gain steam, but now customers must decide whether to design their next high-end packages using existing interconnect schemes or move to a next-generation, higher-density technology called copper hybrid bonding. The decision is far from simple, and in some cases both technologies may be used. Each technology adds new capabilities in next-generation advanced pac... » read more

The Good And Bad Of Auto IC Updates


Keeping automobiles updated enough to avoid problems is becoming increasingly difficult as more complex electronics are added into vehicles, and as the lifetimes of those devices are extended to a decade or more. Modern vehicles are full of electronics. In fact, the value of electronic devices used in modern vehicles is expected to double in the next 10 years, growing to $469 billion by 2030... » read more

Heterogeneous Computing Model Delivers Order-Of-Magnitude Performance Breakthrough


By Srinivas Kodiyalam (NVIDIA) and Samad Parekh (Synopsys) With the ever-increasing demand for more computing performance, the HPC industry is moving towards a heterogeneous computing model, where GPUs and CPUs work together to perform general-purpose computing tasks. In this heterogeneous computing model, the GPU serves as an accelerator to the CPU, to offload the CPU and to increase comput... » read more

Tradeoffs To Improve Performance, Lower Power


Generic chips are no longer acceptable in competitive markets, and the trend is growing as designs become increasingly heterogeneous and targeted to specific workloads and applications. From the edge to the cloud, including everything from vehicles, smartphones, to commercial and industrial machinery, the trend increasingly is on maximizing performance using the least amount of energy. This ... » read more
