Nvidia, Deep Learning, as used with GPU-Accelerated Servers

May 24, 2021

Deep Learning, Nvidia interpretation Deep Learning Concept images Back to server basics, Same Throughput with Fewer Server Nodes To illustrate how throughput and cost savings are related, let’s assume there are two data centers. The CPU-Only data center is comprised of traditional CPU servers and the accelerated data center is comprised of a mix of traditional CPU servers and GPU-accelerated servers. […]

INTEL’s latest H20 Optane memory

May 20, 2021

INTEL has a new consumer-targeted storage product, called Optane H20, as in H twenty, not water. The new device is an M.2 2280 format drive, using QLC (Quad Level Cell) NAND storage running behind an Optane cache layer. This isn’t INTEL’s first try at an Optane-backed hybrid SSD—the first, 2019’s Optane H10, made its way into a few consumer laptops […]

IBM New Memory Class, potential for Neural Processing

May 18, 2021

IBM Research has been working on new non-volatile magnetic memory for over two decades. Non-volatile memory is wonderful for retaining data without power, but it is extremely slow, and does not last forever. Primary computer memory (Dynamic Random Access Memory, or DRAM) is fast but volatile (thats the D part), and on-processor chip memory (Static Random Access Memory, or SRAM) […]

How feasible are 2D film transistors and what lies in the future?

May 17, 2021

Moore’s Law, the famous prediction that the number of transistors that can be packed onto a microchip will double every couple of years, has been bumping into basic physical limits. These limits could bring decades of progress to a halt, unless new approaches are found. One new direction being explored is the use of atomically thin materials instead of silicon as […]

Ford’s GPS-based headlights

May 14, 2021

Prototype headlight system not currently available for specification. The predictive system directs beams into upcoming corners even before drivers may have seen them. Driving at night, especially on unfamiliar roads, can be stressful, with many people choosing to avoid the experience altogether. Manufacturers though are increasingly working on headlight technology to improve road illumination and make driving in the dark easier. Ford, […]

Light detect and Ranging (LiDAR)

May 12, 2021

Earlier this morning Patently Apple posted a report about Apple Vans are out in full force this morning mapping out the streets of Hong Kong. These vans use massive LiDAR sensors on the roof of the vans to capture 360º images. Earlier this year Bloomberg had reported that Apple was in discussions with multiple suppliers of self-driving car sensors known as LiDAR […]

Queueing Theory, Little’s Law

May 11, 2021

In queueing theory, a discipline within the mathematical theory of probability, Little’s result, theorem, lemma, law, or formula is a theorem by John Little which states that the long-term average number L of customers in a stationary system is equal to the long-term average effective arrival rate λ multiplied by the average time W that a customer spends in the system. Customers in a store Imagine a small store with a single counter and an area for […]

Spectre security attack, Intel and AMD

May 10, 2021

Since 2018, an almost endless series of attacks broadly known as Spectre has kept Intel and AMD scrambling to develop defenses to mitigate vulnerabilities that allow malware to pluck passwords and other sensitive information directly out of silicon. Now, researchers say they’ve devised a new attack that breaks most—if not all—of those on-chip defenses. Spectre got its name for […]

Digital System Power, Wireless Power Transmission

May 7, 2021

New Zealand is testing wireless power transmission, first mentioned by Nickolas Tesla. The startup company Emrod has developed a wireless transmission methodology: (1) Collimated RF waves using advanced microwave dish technology. (2) Recognizing birds, or humans might intersect the microwave. (3) Utilizing a recantenna, receiving antenna to convert microwaves back to power. Item (2) would […]

System Level Modeling and Analysis of Processors and SoC Designs

May 6, 2021

Engineers love to optimize their designs, but that implies that there are models and stimulus to automate the process. Process engineers have TCAD tools, circuit designers have SPICE for circuit simulation, logic designers have gate-level simulators, RTL designers use logic simulation, but what is there for the system architects of a processor or SoC design? […]

How L1 and L2 memory chips fit into modern processor chips

May 5, 2021

The development of caches and caching is one of the most significant events in the history of computing. Virtually every modern CPU core from ultra-low power chips like the ARM Cortex-A5 to the highest-end Intel Core i9 use caches. Even higher-end microcontrollers often have small caches or offer them as options — the performance benefits are too large to ignore, even […]

Fine-Grained Performance and Power Analysis in 10 Hours using a Statistical Instruction Set Processor Simulator

May 3, 2021

Architecture exploration, power and performance analysis early in the design flow are mandatory in modern SoC design flow due to complex multi-threaded applications and multi-core processing requirements. Instruction Set Simulator or ISS of a selected processor plays a very important role. However, Current Instruction Set Simulators (ISS) and platform modelers have detailed functional execution, tuned […]
