What is energy optimization?
Power optimization is an attempt to reduce power supply by digital devices, such as integrated circuits, balance of parameters such as size, power and heat scattering. It is a very critical area of the design of electronic components, as many portable electronic devices require high low -power capacity. Components must perform complex functions, but generate as little heat and noise as possible, all wrapped on a very slight surface area. Intensely explored area of digital design, performance optimization is essential for the commercial success of many devices.
The idea of optimizing energy in electronic design began at the end of the 80s. Battery life, heating effects and cooling requirements have become very important of environmental and economic reasons. Adaptation to increasingly complex components to smaller chips size has become vital to securing inýbes of smaller devices candle functionality. However, the heat generated by including so many components has become the main problem. Factors such as equipment and reliability are also affected by heat.
to the scale of chips, reduced matrix size and still have maximum power at acceptable temperature levels requires the time to invest in energy optimization methodologies. Manual optimization performance is impossible for existing chips such as integrated circuits because they contain millions of components. Designers usually perform energy optimization by limiting unnecessary energy, which is mostly speculation, architectural and program waste. All these methods try to reduce energy waste from the level of circuit design and application.
Program waste occurs when the top microprocessor performs commands that are not necessary. The execution of these commands does not change the content of memory and registers. Elimination of Waste PRogram means reducing the implementation of dead instructions and getting rid of quiet trades. Speculation waste occurs when the processor loads and performs instructions outside the unresolved branches. Architectural waste happens when structures such as cache, predictors of branch and queues of teaching are too large or too small.
, mostly designed to hold large quantities, architectural structures are usually not used to their full capacity. On the contrary, their smaller also increases energy consumption due to greater wrong speculation. Successful performance optimization requires the use of the system level to select components that consume very little power. All possible combinations of these types of components can be explored in the design phase. Reducing the amount of switching activities also requires less energy consumption.
Some other approaches used to optimize performance include hourly gates, sleep modes and better logical design. Renačovní, Bianging paths and coding status are anotherLogical methods that can reduce energy consumption. Some microprocessors designers also use special formats for code files that insert the power control functions.
