Memory-Based Cyberattacks Become More Complex, Difficult To Detect


Memories are becoming entry points for cyber attacks, raising concerns about system-level security because memories are nearly ubiquitous in electronics and breaches are difficult to detect. There is no end in sight with hackers taking aim at almost every consumer, industrial, and commercial segment, and a growing number of those devices connected to the internet and to each other. According... » read more

How Memory Design Optimizes System Performance


Exponential increases in data and demand for improved performance to process that data has spawned a variety of new approaches to processor design and packaging, but it also is driving big changes on the memory side. While the underlying technology still looks very familiar, the real shift is in the way those memories are connected to processing elements and various components within a syste... » read more

HBM-based scalable multi-FPGA emulator for Quantum Fourier Transform (QFT)


New technical paper titled "A Scalable Emulator for Quantum Fourier Transform Using Multiple-FPGAs With High-Bandwidth-Memory" from researchers at Tohoku University in Japan. Abstract: "Quantum computing is regarded as the future of computing that hopefully provides exponentially large processing power compared to the conventional digital computing. However, current quantum computers do not... » read more

Keeping IC Packages Cool


Placing multiple chips into a package side-by-side can alleviate thermal issues, but as companies dive further into die stacking and denser packaging to boost performance and reduce power, they are wrestling with a whole new set of heat-related issues. The shift to advanced packaging enables chipmakers to meet demands for increasing bandwidth, clock speeds, and power density for high perform... » read more

Standardizing Chiplet Interconnects


The chip industry is making progress on standardizing the infrastructure for chiplets, setting the stage for faster and more predictable integration of different functions and features from different vendors. The ability to choose from a menu of small, highly specialized chips, and to mix and match them for specific applications and use cases, has been on the horizon for more than a decade. ... » read more

DRAM Choices Becoming Central Design Considerations


Chipmakers are paying much closer attention to various DRAM options as they grapple with what goes on-chip or into a package, elevating attached memory to a critical design element that can affect system performance, power, and cost. These are increasingly important issues to sort through with a number of tradeoffs, but the general consensus is that to reach the higher levels of performance ... » read more

Choosing The Right Server Interface Architectures For High Performance Computing


The largest bulk and cost of a modern high-performance computing (HPC) installation involves the acquisition or provisioning of many identical systems, interconnected by one or more networks, typically Ethernet and/or InfiniBand. Most HPC experts know that there are many choices between different server manufacturers and the options of form factor, CPU, RAM configuration, out of band management... » read more

Clocks Getting Skewed Up


At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it's fraught with the most problems at the physical level. To some, the clock is the AC power supply of the chip. To others, it is an analog network almost beyond analysis. Ironically, there are no languages to describe clocking, few tools t... » read more
