Steep Spike For Chip Complexity And Unknowns
By Ed Sperling - 05 May, 2021 - Comments: 0

Cramming more and different kinds of processors and memories onto a die or into a package is causing the number of unknowns and the complexity of those designs to skyrocket. There are good reasons for combining all of these different devices into an SoC or advanced package. They increase functionality and can offer big improvements in performance and power that are no longer available just b... » read more

Power/Performance Bits: May 4
By Jesse Allen - 04 May, 2021 - Comments: 0

Speculative execution vulnerable again Computer scientists from the University of Virginia and University of California San Diego warn of a processor architecture vulnerability that gets around the techniques used to secure processors in the wake of Spectre. In 2018, Spectre and the similar Meltdown vulnerability were announced. These types of attacks could allow malicious agents to exploit... » read more

Power/Performance Bits: April 27

Energy-harvesting shirt Engineers at the University of California San Diego developed a 'wearable microgrid' that harvests and stores energy from the human body to power small electronics. The microgrid consists of three main parts: sweat-powered biofuel cells, motion-powered triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen pri... » read more

Tapping Into Non-Volatile Logic
By Bryon Moyer - 21 Apr, 2021 - Comments: 0

Research is underway to develop a new type of logic device, called non-volatile logic (NVL), based on ferroelectric FETs. FeFETs have been a topic of high interest at recent industry conferences, but the overwhelming focus has been using them in memory arrays. The memory bit cell, however, is simply a transistor that can store a state. That can be leveraged in other applications. “Non-v... » read more

Power/Performance Bits: April 20

Multiplexing twisted light Researchers from University of California San Diego and University of California Berkeley found a way to multiplex light by using discrete twisting laser beams from antennas made up of concentric rings. "It's the first time that lasers producing twisted light have been directly multiplexed," said Boubacar Kanté, an Associate Professor at UC Berkeley's Department ... » read more

Faster Than Moore’s Law: Exponential Innovation In Electromagnetic Simulation
By Larry Williams - 13 Apr, 2021 - Comments: 0

Moore’s Law is the most iconic statement of exponential technology advancement, doubling transistor count and hence functional performance every 24 months. Many pundits [1-3] have observed that while technology advancement is exponential, human expectations are linear. We often fail to anticipate when a technology may arrive in short order. Electromagnetic simulation has delivered exponential... » read more

Speedy data transfer Researchers from MIT, Intel, and Raytheon developed a new data transfer system that both boosts speeds and reduces energy use by taking elements from both traditional copper cables and fiber optics. "There's an explosion in the amount of information being shared between computer chips -- cloud computing, the internet, big data. And a lot of this happens over conventiona... » read more

Many Chiplet Challenges Ahead
By Brian Bailey - 12 Apr, 2021 - Comments: 0

Over the past couple of months, Semiconductor Engineering has looked into several aspects of 2.5D and 3D system design, the emerging standards and steps that the industry is taking to make this more broadly adopted. This final article focuses on the potential problems and what remains to be addressed before the technology becomes sustainable to the mass market. Advanced packaging is seen as ... » read more

Verification Effectiveness In The Face Of FPGA Complexity: The 2020 Wilson Research Group Functional Verification Study
By Harry Foster - 08 Apr, 2021 - Comments: 0

Making informed decisions backed by good data is the key to success in highly competitive, robust markets such as FPGA design and verification. Helping our community in that endeavor is the motivation behind the worldwide Wilson Research Group Functional Verification Study. We also use that information to make sure our research and development efforts continue to deliver the solutions our cu... » read more

Interconnects In A Domain-Specific World
By Brian Bailey - 08 Apr, 2021 - Comments: 0

Moving data around is probably the least interesting aspect of system design, but it is one of three legs that defines the key performance indicators (KPI) for a system. Computation, memory, and interconnect all need to be balanced. Otherwise, resources are wasted and performance is lost. The problem is that the interconnect is rarely seen as a contributor to system functionality. It is seen... » read more
