Week In Review: Auto, Security, Pervasive Computing


Automotive Features of Toyota’s key fobs for entering vehicles get turned off when drivers do not start paying a subscription fee when the complementary subscriptions end, says an article in Ars Technica. SiLC Technologies announced its compact Eyeonic Vision Sensor, a FMCW lidar sensor, is now commercially available. The sensor has a silicon photonic chip that keeps a lidar’s size down... » read more

Blog Review: Dec. 15


Arm's Hannah Peeler, Joshua Randall, and Zach Lasiuk examine the carbon cost of data centers and introduce a tool that allows users to make informed decisions about the carbon impact of their compute workloads. Synopsys' Kenneth Larsen provides a primer on the fundamentals of quantum computing, the role of photonics in building quantum systems, and the future potential impact on chip design.... » 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

Revving Up SiC And GaN


Silicon carbide (SiC) and gallium nitride (GaN) are becoming more popular for power electronics, particularly in automotive applications, driving down costs as volumes scale up and increasing the demand for better tools to design, verify, and test these wide-bandgap devices. Both SiC and GaN are proving essential in areas such as battery management in electric vehicles. They can handle much ... » read more

Week In Review: Design, Low Power


Intel intends to take Mobileye public in mid-2022 on a US market through an IPO of newly issued stock. The subsidiary, which Intel acquired in 2017, develops SoCs for ADAS and autonomous driving solutions. Mobileye has achieved record revenue year-over-year with 2021 gains expected to be more than 40 percent higher than 2020, highlighting the powerful benefits to both companies of our ongoing p... » 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

Innovations In Sensor Technology


Sensors are the “eyes” and “ears” of processors, co-processors, and computing modules. They come in all shapes, forms, and functions, and they are being deployed in a rapidly growing number of applications — from edge computing and IoT, to smart cities, smart manufacturing, hospitals, industrial, machine learning, and automotive. Each of these use cases relies on chips to capture d... » read more

Moving From AMBA ACE to CHI For Coherency


Introduced back in 2011, ACE (AXI Coherency Extensions) grew from the existing AXI protocol to satisfy the cache coherency maintenance demands of SoCs with multi core processors and shared caches in smart phones, mobile computers, and servers. It added new channels for cache communication, extra signals to allow new transaction for coherency support, and five state model for caches. AXI + A... » read more

The Physics Of Ports And Associated Ground For EM Simulators Serving RF Designs


The use of ports in electromagnetic (EM) simulators has evolved and matured over the years to make real-world design simulations practical. Having a foundational understanding of ports provides an intuitive skill in their proper selection and use in conjunction with circuit simulation. In this white paper, we examine ports common to EM simulators, which are the most common simulators for microw... » 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
