Zedboard power consumptionThese options are important for many Zynq-based systems that are designed to run from battery power or other constrained power sources. There are several elements of the design we can look at, from the system and board level down to the PS and PL levels inside of the Zynq SoC. At the system level, we can look at component selection. We can use low-voltage devices wherever possible because they will have a lower static power consumption. One of the simpler choices would be selecting a single-core Zynq SoC as opposed to a dual-core device. There are two categories we can consider when it comes to reducing power consumption in Zynq-based systems:. The first option allows us to reduce the power consumption after we have detected that the system has been inactive for a period and should therefore enter a low-power mode to prolong operating life on a battery charge. The second option allows us to make the best use of the battery capacity while operating. Most of these techniques relate to how we configure the clocking architecture within the PS. We can use this flexibility to reduce the power consumption of the Zynq PS. The first approach we can take is to trade off performance against power consumption. Of course, this also reduces APU performance. However, as engineers one of our roles is to understand the overall system requirements and balance them. CMOS power dissipation is frequency dependent so we reduce power consumption by reducing the APU frequency, which has the potential to significantly reduce PS power dissipation. The clocking architecture allows downstream connections to use any one of the PLL sources, so a clocking scheme that uses fewer than all three PLLs results in lower power dissipation as unused PLLs can be disabled and their power consumption eliminated. In addition, the application being developed may not require the use of all peripherals within the PS. I performed a very simple experiment with a MicroZed board by inserting an ammeter into the USB power port supplying power to the MicroZed. So we see that turning off unused PLLs can have a big effect on power consumption. For many applications, this may not be feasible but for some it may, so I thought it worthy of a test. Sign In Help.

Power Rails monitoring
ZED is an amazing little desk for small band mixing. It is ultra portable for carrying to the gig, and can be used for recording live or in the studio. Equipped with professional XLR stereo outputs and a flexible monitoring section with headphone and speaker feed outputs. Getting audio to and from a computer easily is now a common requirement for live sound and music production. The way this has been implemented on ZED is super-flexible and super-easy! No longer do you need to fiddle around the back of your PC to get to the soundcard inputs, only to find that the levels are all wrong and noisy. CD quality audio to and from your PC or Mac. ZED features a responsive 3-band, swept mid frequency EQ design which utilises MusiQ — with optimised slope or Q factor for equalising individual instruments. These newly designed inputs have been crafted with the aim of replicating the sound of a classic guitar or instrument tube pre-amp in a combo or head amp. An extremely high input impedance ensures loading on pick-ups is minimal and a Class A FET field effect transistor circuit powered from 48V is employed to give the valve-like gain stage. All this makes for a wonderfully natural sound to be reproduced from the instrument, full of warmth and character.

We purchase our own TVs and put them under the same test bench, so that you can compare the results easily. No cherry-picked units sent by brands. If you wonder how much electricity a TV uses, check the following calculator to estimate the annual electricity cost of a television as defined by size, viewing habits, electricity cost, and TV technology. Energy consumption is a much smaller factor in buying appliances today, and TVs especially reflect this. Modern technologies such as LED and OLED have brought television power usages down a fair margin, and long gone are the days of inefficient CRTs and Plasma sets that could run up electricity costs by a good amount. TVs have grown to be larger with time. While great strides in efficiency have allowed us to have TVs that consume significantly less energy than before, bigger sizes inevitably have bigger requirements. Most of the time though, this just amounts to TVs consuming about the same as they used to a couple of years ago. They are better TVs overall though, and they do get much brighter. Larger TVs also leads to more heat, as any circuit will. As you can see in this chart plotting TVs from andthere is a definite link between size and power consumption. Some features, such as full-array local dimming, are more costly, both to build and use. Something to keep in mind is that almost all the electricity your TV uses ends up becoming heat. The heat generated by the TV just ends up slightly lowering the amount of heating that your heater has to do. In summer, though, or in areas that are warm year-round, the extra heat can be a problem. If this extra heat is a big problem for you, you may want to make energy consumption one of the things you look at before diving in and buying a TV. Not only does consumption scale with size, but it also almost perfectly scales with brightness. As you can see above, raising your brightness from minimum progressively leads to higher consumption and inevitably higher costs. Even if the difference is relatively marginal cost-wise, it is quite obvious that the Samsung MU, even if it's about as bright as the LG C7, consumes significantly less power. The bigger or brighter your TV, the more power it will take to run you can see how much power a TV uses with our power consumption calculator. Sign Up Log In View All. New — —. Sign Up Log In.

I'm new to zedboard. Does anyone know if there is a way that I can measure the power consumption of a particular application running on the zedboard? You can measure total board power by measuring the voltage across pins 1 and 2 of J21 and divide by 10milliohms to get the input current. Then multiply that by your measured input voltage should be 12V but measure it anyway for more accurate results. If you need more specific power numbers like for each individual rail there is no easy way to do that. That type of power measurement would mean modifying the PCB to insert current loops on all the outputs. Just monitoring the change in total board power should give you a pretty good idea of relative power changes though. Thanks Chris. I'm running different applications on the board each time and trying to do a comparison, but the measurements I got were always 2. Hi, Do you figure out why you always get the same results when running different applications? I have a same problem on the measurement :. Skip to main content. Login Register. Search form Search.
