Automotive Outlook: 2022


The auto industry is widening its focus this year, migrating to new architectures that embrace better security, faster data movement, and eventually more manageable costs. The auto industry is facing both short-term and long-term challenges. In the short term, the chip shortage continues to top the list of concerns for the world's automakers. That shortage has delayed new vehicle deliveries,... » read more

Building Multipurpose Systems With Dynamic Function Exchange


One of the most-common oversights that designers can make is to not fully use available system resources. Typically, design and optimization efforts are focused on performance and efficiency. Mission-critical and real-time tasks are allocated hardware-based resources to accelerate their execution. But when large portions of the architecture are underutilized – in other words, they remain idle... » read more

2021 Top Tech Videos


While the world’s chip shortage dominated the 2021 headlines, the semiconductor industry blazed new trails with the increased electrification of cars, focused AI applications, improving power/performance, better utilization of data deluges, dealing with design challenges in advanced nodes and much more focus on chip security. Semiconductor Engineering’s Tech Talks reflected these focus a... » read more

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

Week In Review: Design, Low Power


Memory CEA-Leti demonstrated 16-kbit ferroelectric random-access memory (FeRAM) arrays at the 130nm node. It utilizes back-end-of-line (BEOL) integration of TiN/HfO2:Si/TiN ferroelectric capacitors as small as 0.16 µm² and solder reflow compatibility for the first time for this type of memory. The researchers anticipate it will be useful for embedded applications such at IoT and wearable dev... » read more

Radiation Hardening Chips For Outer Space


What’s the difference between radiation tolerant and radiation hardening, and where is each one used? Minal Sawant, director of the aerospace and defense vertical market at Xilinx, talks about different striations in the Earth’s atmosphere, how those various levels can affect radiation, and what impact that has on the functionality of increasingly dense chip circuits over extended periods o... » read more

Amdahl Limits On AI


Software and hardware both place limits on how fast an application can run, but finding and eliminating the limitations is becoming more important in this age of multicore heterogeneous processing. The problem is certainly not new. Gene Amdahl (1922-2015) recognized the issue and published a paper about it in 1967. It provided the theoretical speedup for a defined task that could be expected... » read more

Big Changes Ahead For Inside Auto Cabins


The space we occupy inside our vehicles is poised to change from mere enclosure to participant in the driving experience. Whether for safety or for comfort, a wide range of sensors are likely to appear that will monitor the “contents” of the vehicle. The overall approach is referred to as an in-cabin monitoring system (ICMS), but the specific applications vary widely. “In-cabin sensing... » read more

Why It’s So Difficult — And Costly — To Secure Chips


Rising concerns about the security of chips used in everything from cars to data centers are driving up the cost and complexity of electronic systems in a variety of ways, some obvious and others less so. Until very recently, semiconductor security was viewed more as a theoretical threat than a real one. Governments certainly worried about adversaries taking control of secure systems through... » read more

Innovative Technology Drives Rapid Deployment Of New 5G Products, Services, And Business Models


The wireless future is about developing the most compelling products using a combination of advanced technologies to maximize system performance, while optimizing both cost and power. Doing so will unlock deployment of new 5G products and services for mobile operators and the whole 5G ecosystem, from businesses to consumers to the economy. With 5G offering so much potential, how can the industr... » read more
