Digital System Power for GPUs

February 9, 2021

Digital System Power for GPUs is an area of rapid development, as even small improvements in power efficiency can have significant impacts on energy consumption and the environment. Optimizing GPU power consumption is crucial for enhancing performance and reducing the carbon footprint of data centers and personal computing devices. One notable advancement is the Apple […]

Digital System Power for Robotics

February 8, 2021

Digital System Power for Robotics might be related to arm motion, reducing the power required for taking certain actions in an optimal way; or robotic power considerations might relate to an EV active-suspension, for example. The robotic arm may be plugged into the grid, while the EV active-suspension is most likely a mobile battery? In either […]

Digital System EV Battery Considerations

February 6, 2021

EV Battery Management: Keeping Your Electric Vehicle Running Smoothly Unlike a simple flashlight battery that you just replace, electric vehicle (EV) batteries are complex and require constant monitoring for optimal performance and lifespan. This guide dives into the world within your EV’s battery and explains how technology keeps it running like a champ. Inside Your […]

Digital System Power for Sensors and Analog Components

February 5, 2021

Electric vehicles (EVs) rely on a network of sensors to monitor everything from battery health to tire pressure. These sensors play a vital role in ensuring your EV operates safely and efficiently, but they also consume power. This can impact your overall battery life. Let’s break down how sensor power works in an EV and […]

Digital System On-Chip Electro-Migration relation to Power

February 4, 2021

Electro-migration is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms. The effect is important in applications where high direct current densities are used, such as in microelectronics and related structures. As the structure size in electronics such as integrated circuits (ICs) decreases, the practical significance of this effect increases. Electro-Migration is a secondary effect of power being distributed […]

Digital System Hardware Power Monitor

February 3, 2021

A hardware monitor is a common component of modern motherboards, which can either come as a separate chip, often interfaced through I²C or SMBus, or as part of a Super I/O solution, often interfaced through Low Pin Count (LPC).These devices make it possible to monitor temperature in the chassis, voltage supplied to the motherboard by the power supply unit and the speed of the computer fans that are connected directly to one of the fan headers […]

Digital System Strategies to Reduce Power

February 2, 2021

Power Up Your Tech: Strategies to Reduce Power Consumption in Digital Systems In today’s world, our devices are constantly demanding power. From laptops and smartphones to gaming consoles and servers, keeping these digital systems running smoothly can eat into our energy bills. But fear not, there are clever strategies that developers and engineers can use […]

Digital System Power Table Configuration

February 1, 2021

A Power_Manager can be updated via the Power Table directly, or through the use of RegEx expressions that will manually alter the same Power Table entries. A Power_Manager Table references the devices included in the power domain, including specific state names, speed (Mhz), t_OnOff (time), and operating voltages. The power domain may be a single centralized or decentralized power […]

Digital System Device Junction Temperature vs. Power

January 27, 2021

Chip expressions used to determine Chip Device from a Texas Instrument white paper on junction temperatures, ultimately determining junction temperature >> device based on power. The actual chip junction temperature may differ depending on parameters entered below, especially Theta_CS => case to heatsink or vapor chamber; previously discussed. Steps outlined: • Measure the case temperature using the […]

Digital System Vapor Chamber vs. Heat Sink

January 25, 2021

Digital Systems must maintain a Thermal Design Power (TDP) requirement per chip, else chip reliability may be drastically reduced, ultimately resulting in a failure? Currently, the TDP requirement can be maintained, if heat energy can be removed faster than power, energy is added. Vapor Chamber: (1) Vapor Chamber is a heat accumulator, exchanger that limits the maximum temperature based […]

Digital System Centralized vs. Distributed Power Management

January 22, 2021

Power management can be either centralized, distributed, or a combination of both. The type of devices supported by a power manager chip, or integrated into a system-on-chip presents different power management alternatives. If the devices, such as memory chips, are homogenous; then a centralized power manager function becomes more attractive for a number of reasons: (1) Same […]

How to order Digital System Task or Thread Power?

January 20, 2021

Prior blog on peak and average power highlights benefits of reordering device activity to increase Digital System reliability. This blog carries this concept one step further by accumulating task or thread requests to avoid leaving memory in Active state (full power) spread out over time. The type of task or thread determines if this is feasible. […]
