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 […]

Investment in Avionics spurs new systems engineering methodologies

May 3, 2021

Reducing trade barriers in technology exchange between US and India will create a new market for avionics organizations in India. These companies must compete on reliability, greater integration and quality, not on price alone.  To facilitate this, the design teams will require new methodologies to improve engineering productivity.  These methodologies must be done during the […]

Volkswagen plans to design own autonomous-driving processor chips

May 3, 2021

HAMBURG, Germany — Volkswagen plans to design and develop its own high-powered chips for autonomous vehicles, along with the required software, Chief Executive Herbert  Diess told a German newspaper. “To achieve optimal performance in light of the high demands that exist for cars,  software and hardware have to come out of one hand,” Diess told Handelsblatt. Volkswagen did not plan to build […]

Why do we need system modeling?

April 30, 2021

To cause a system upgrade, we must first understand what we are attempting to change as a system, which necessitates the creation of a system model of it. We think of a system as just a summation of its parts and thus requires no special attention. It is necessary to change our approach in which […]

Stochastic Modeling; over, under Delay importance

April 30, 2021

VisualSim can be used to construct stochastic models using SystemResource blocks; where priority and preemption can be factored into the shared resource.  Stochastic models are in contrast to detailed cycle-accurate models.  If stochastic models are constructed, then they can use time estimates for first order of approximation; or a specific number of cycles with the SystemResource specifying the SystemResource speed in MHz […]

Processing Basics

April 29, 2021

Software Pipeline In software engineering, a pipeline consists of a chain of processing elements (processes, threads, coroutines, functions, etc.), arranged so that the output of each element is the input of the next; the name is by analogy to a physical pipeline. Usually some amount of buffering is provided between consecutive elements. The information that flows in these pipelines is often a stream of records, bytes, or bits, and the elements of a pipeline […]

Apple M2 Chip using AI or deep learning

April 28, 2021

Apple’s M2, the successor to the M1 and the SoC variant expected to ship in higher-end systems, is said to have now taped out on TSMC’s N5P process [5nm+].  N5P is said to be a small improvement over TSMC’s N5 node, offering an additional 10 percent improvement to power consumption and a 5 percent performance improvement over […]

Google Quantum Sycamore processor

April 27, 2021

Sycamore is a quantum processor created by Google Inc.’s Artificial Intelligence division.  It comprises 53 q-bits, while actually having 54 q-bits.  In 2019, Sycamore completed a task in 200 seconds that Google claimed, in a Nature paper, would take a state-of-the-art supercomputer 10,000 years to finish. Thus, Google claimed to have achieved quantum supremacy. To estimate the time that would be taken by a classical supercomputer, Google […]

Earthquake Prediction using AI or deep learning

April 26, 2021

Forecasting earthquakes is an important problem in Earth science, because of their devastating consequences. The success of earthquake prediction can potentially save many lives. Current scientific studies related to earthquake prediction focus on when and where it will occur and its magnitude. Different technologies have been used to address this, such as mathematical analysis, machine learning algorithms like […]

Quantum counting algorithm

April 23, 2021

A Quantum counting algorithm is for efficiently counting the number of solutions for a given search problem. The algorithm is based on the quantum phase estimation algorithm and on Grover’s search algorithm. Counting problems are common in diverse fields such as statistical estimation, statistical physics, networking, etc. As for quantum computing, the ability to perform quantum counting efficiently is needed in order to use […]

Quantum Internet

April 21, 2021

Purdue University engineers have addressed an issue barring the development of quantum networks that are big enough to reliably support more than a handful of  users. The method, demonstrated in a paper published in Optica, could help lay the groundwork for when a large number of quantum computers, quantum sensors and other quantum  technology are ready to go […]
