Bellovin, Jason Nieh Email privacy is of crucial importance. Existing email encryption approaches are comprehensive but seldom used due to their complexity and inconvenience. We take a new approach to simplify email encryption and improve its usability by implementing receiver-controlled encryption: To avoid the problem of users having to move a single private key between devices, we implement per-device key pairs:

Arteris Upgrades NoC for AI [Brief Item] Whereas human intelligence lives in neurons and synapses, artificial intelligence resides in transistors and wires.
Arteris IP helps engineers design the wires. At the recent Linley Fall Processor Conference, the company announced several upgrades for its licensable network-on-a-chip NoC technology, including some AI features.
Although the upgrades are useful for designing the interconnects on any chip, some features are particularly useful for processing deep neural networks DNNs. For example, a new intelligent multicast feature enables a source such as a CPU to simultaneously broadcast the same data to multiple destinations such as memory-mapped coprocessors.
In a multicore AI chip, it can distribute DNN-training weights and image-map updates to multiple cores at different memory addresses.
Your teenagers are safely home, but do you know where your cows are? Tracking farm animals is only one application for a low-power location device that employs a global navigation satellite system GNSS.
Others include cargo logistics, smart-city infrastructure, remote patient monitors, and any mobile IoT client. But conventional GNSS positioning may use too much energy for a small battery-powered tracking device. It's licensable intellectual property IP for chip designers that's based on previous Ensigma designs for Wi-Fi and Bluetooth.
At the recent Linley Fall Processor Conference, the company announced three new variants that omit some features to reduce cost and power. The LSA follows a new company strategy. Although NXP has always offered industrial processors and microcontrollers, networking was the main target for the high-performance QorIQ line.
More recently, the convergence of wired and wireless communications with industrial automation is opening new opportunities while the company's sales decline in the network-infrastructure market.
The new trend is called "Industrial IoT" or "Industry 4. Comparison of three embedded processors for industrial applications: This model accesses DRAM through external buffer chips, which provide industry-leading memory bandwidth and capacity for enterprise servers that handle large workloads.
They provide less bandwidth but are better suited to lower-cost systems such as web servers that handle threads with modest memory requirements. By offering Power9 products with both types of memory subsystems, IBM is targeting a wide range of servers with the same basic chip design.
Power9 offers the best per-core performance of any server processor. SPECint benchmark comparison. Comparison of high-end server processors: At the recent Xilinx Developer Forum, the company also replaced the Everest code-name with the official brand: Versal, a portmanteau of "versatile" and "universal.
Although we doubt other vendors will adopt that name, we agree these devices are full-fledged SoCs containing programmable logic, not just FPGAs with some SoC elements.
Some Versal products will include the new software-programmable accelerators described at Hot Chips in August. Xilinx Versal SoC block diagram. Although Fujitsu's product roadmap still shows a 7nm SPARC design in progress, the company's next-generation supercomputer switches to a custom bit Arm processor built in the same technology.
This powerful core chip will appear in the mammoth Post-K supercomputer scheduled to debut in The company has initial silicon samples of the chip and demonstrated a single-rack Post-K prototype at a supercomputer conference earlier this year.
The company estimates Post-K will be about x faster than its predecessor, which contains 88, processors. Fujitsu A64FX block diagram. Comparison of Fujitsu supercomputer processors: They upend the traditional orientation of FPGAs by surrounding the programmable gates with more of everything: At the recent Hot Chips conference, Xilinx focused on one new aspect: Xilinx Everest conceptual block diagram.
Configuring the mesh as a data-flow graph. The folks at AMD will sell you one anyway, just because And because Intel can't. Video editing, software development, and other compute-intensive tasks are the justification for these monster chips.The history of computing hardware covers the developments from early simple devices to aid calculation to modern day computers.
Before the 20th century, most calculations were done by humans. Early mechanical tools to help humans with digital calculations, such as the abacus, were called "calculating machines", called by proprietary names, .
Since , cloud computing has come into existence. In August , Amazon created subsidiary Amazon Web Services and introduced its Elastic Compute Cloud (EC2). In April , Google released Google App Engine in beta. In early , NASA's OpenNebula, enhanced in the RESERVOIR European Commission-funded project, became the first open-source software for deploying private and hybrid .
Intraclass correlation (ICC) is one of the most commonly misused indicators of interrater reliability, but a simple step-by-step process will do it right. A lot of time and effort can be wasted collecting data and analyzing the results. Fortunately, Overall Equipment Effectiveness, or OEE, is one of those metrics that is easily calculated and can be applied to any process, department, or the entire organization.

The workforce is changing as businesses become global and technology erodes geographical and physical timberdesignmag.com organizations are critical to enabling this transition and can utilize next-generation tools and strategies to provide world-class support regardless of location, platform or device.
