Book excerpt: In recent years, power consumption has become a major concern in the electronic industry. Power reduction can be accelerated in the design cycle by fast and accurate power estimation tools. Since the units of lower-levels of design abstraction are transistors or gates, power estimation becomes a slow process at these levels. Therefore designers need to have tools for fast and accurate power estimation at the higher levels of design abstraction such as register transfer level (RTL). A novel RTL power estimation technique called CRAB-RPE will be presented in this thesis. The CRAB power model is built upon four important properties which most of the previous RTL models did not support at the same time. First, the model is based solely on the first and second-order primary input bit-level transition probabilities which provide detailed information about the primary input bit activity dependency of the circuit. Second, the model is based on the power characterization of a microarchitecture library with a complete range of primary input bit transition probabilities without any assumptions about this activity. Third, the pairwise spatial correlations of the primary input nodes are considered by including second-order crossterms of the primary input switching probabilities. Fourth, the first-order temporal correlations of the primary input bits are considered by including 1 to 1 and binary switching transition probabilities. With the proposed model, fast power estimation can be achieved from input bit-level statistics without further simulation. The model was evaluated using the ISCAS combinational circuit benchmarks and other commonly used micro-architectural circuit blocks. Second-order terms were observed to be important for modeling the low bit activity effects on power dissipation. The CRAB power model returned under 5% of the low-level simulator estimates for either biased single, pair PIN statistics or uniform white noise, DBT-like data.

This book was released on 2018 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a chip design project, early design planning has a strong impact on the schedule and the cost of design. Power estimation is part of early design planning, and it greatly affects design decisions. Power modeling performed at a high level of abstraction is fast but inaccurate due to lack of circuit switching activity information. By contrast, power modeling performed at a low level of abstraction is more accurate as the synthesized circuit synthesis is known, but this simulation is typically slow. This report explores a power modeling approach performed at register transfer level (RTL). It exploits machine learning models in order to have a fast yet relatively accurate cycle-by-cycle power estimation. The approach is data-dependent, where cycle-specific models are trained based on the switching activity of signals obtained from RTL simulation and cycle-by-cycle power values obtained from a reference gate-level simulation of an existing RTL design. Therefore, if any changes are applied to the RTL design, re-training of models is required. The approach aims at obtaining fast yet accurate power predictions for new invocations of a given trained model using signal activity information collected during simulation of the unmodified RTL. At a low level, the complete visibility of signals in a design unintuitively might cause overtraining the model leading to inaccurate estimation. The suggested model employs automatic feature selection in each cycle. Based on the invocations used to train the cycle-by-cycle models, only signals that may switch during a given cycle will be selected as the features for their respective cycle-specific model. The method was tested on an 8-by-8 DCT design and the power estimates were within 6.5% of those from a commercial power analysis tool. This report also simulates and compares the approach of cycle-specific models to the approach of a single global model for all cycles and show that the cycle-specific approach is twice as accurate.

This book was released on 2003-10-02 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welcome to the proceedings of PATMOS 2003. This was the 13th in a series of international workshops held in several locations in Europe. Over the years, PATMOS has gained recognition as one of the major European events devoted to power and timing aspects of integrated circuit and system design. Despite its signi?cant growth and development, PATMOS can still be considered as a very informal forum, featuring high-level scienti?c presentations together with open discussions and panel sessions in a free and relaxed environment. This year, PATMOS took place in Turin, Italy, organized by the Politecnico di Torino, with technical co-sponsorship from the IEEE Circuits and Systems Society and the generous support of the European Commission, as well as that of several industrial sponsors, including BullDAST, Cadence, Mentor Graphics, STMicroelectronics, and Synopsys. The objective of the PATMOS workshop is to provide a forum to discuss and investigate the emerging problems in methodologies and tools for the design of new generations of integrated circuits and systems. A major emphasis of the technical program is on speed and low-power aspects, with particular regard to modeling, characterization, design, and architectures.

Download or read book Power Estimation on Electronic System Level using Linear Power Models written by Stefan Schuermans and published by Springer. This book was released on 2018-12-14 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a flexible and largely automated methodology for adding the estimation of power consumption to high level simulations at the electronic system level (ESL). This method enables the inclusion of power consumption considerations from the very start of a design. This ability can help designers of electronic systems to create devices with low power consumption. The authors also demonstrate the implementation of the method, using the popular ESL language “SystemC”. This implementation enables most existing SystemC ESL simulations for power estimation with very little manual work. Extensive case-studies of a Network on Chip communication architecture and a dual-core application processor “ARM Cortex-A9” showcase the applicability and accuracy of the method to different types of electronic devices. The evaluation compares various trade-offs regarding amount of manual work, types of ESL models, achieved estimation accuracy and impact on the simulation speed. Describes a flexible and largely automated ESL power estimation method; Shows implementation of power estimation methodology in SystemC; Uses two extensive case studies to demonstrate method introduced.

This book was released on 2010-07-23 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human lives are getting increasingly entangled with technology, especially comp- ing and electronics. At each step we take, especially in a developing world, we are dependent on various gadgets such as cell phones, handheld PDAs, netbooks, me- cal prosthetic devices, and medical measurement devices (e.g., blood pressure m- itors, glucometers). Two important design constraints for such consumer electronics are their form factor and battery life. This translates to the requirements of reduction in the die area and reduced power consumption for the semiconductor chips that go inside these gadgets. Performance is also important, as increasingly sophisticated applications run on these devices, and many of them require fast response time. The form factor of such electronics goods depends not only on the overall area of the chips inside them but also on the packaging, which depends on thermal ch- acteristics. Thermal characteristics in turn depend on peak power signature of the chips. As a result, while the overall energy usage reduction increases battery life, peak power reduction in?uences the form factor. One more important aspect of these electronic equipments is that every 6 months or so, a newer feature needs to be added to keep ahead of the market competition, and hence new designs have to be completed with these new features, better form factor, battery life, and performance every few months. This extreme pressure on the time to market is another force that drives the innovations in design automation of semiconductor chips.
