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. […]

VisualSim vs. Simulink, how to choose your ideal simulation platform?

January 20, 2021

Do you know if the modeling and simulation software, that you are currently using is the right platform? Can your analysis rise to an abstract level to optimize your system architecture? If yes, what would be the best simulation platform for you? Let us help you in solving such and more concerns. In this article […]

How to interpret Digital System Peak vs. Average Power?

January 19, 2021

Peak power for a Power Manager or power domain, is an indication that several devices are in the Active (full power) state at the same time, such that the peak, or instantaneous power is at a Maximum. In a clocked system, this may indicate that several devices are active at the same time for a particular […]

Accurate Measurement of Latency and Throughput of Time Sensitive Networks

October 22, 2020

A few years ago, engineers in the automotive industry worked on improving the mechanical performance of clutch transmissions, exhaust systems and adding a turbocharger. Due to low data rates, CAN and CAN-FD functioned well for these applications. Today every vehicle shipped has an average of about 60 – 100 complex sensors, higher in the case […]

Exploring the performance and power management of a real-time video application

September 30, 2020

Problem statement The requirement was to select an appropriate hardware platform for a MPEG video application so as to optimize the performance and power usage of the application. As part of its functioning, the application receives the data on the input sensor, for example, a light sensor. After the processing, the output is displayed on […]
