Turn: http://blog.sina.com.cn/s/blog_4e00cfd30100a1wk.html In FPGA design, wiring problems caused by unreasonable design often occur.Clock Control and multi-fan out problems. The clock isYou do not need to use the global clock resource bufg in FPGA to control the trigger clock along the input end.InsteadThe signal generated by the combination logic and other time series logic (such as the divider) is used as the trigger clock along the input en

To really realize the low noise of the cooling fan, the choice of fan bearing is very important, the different type of fan bearing, its noise control difference is very big. How to choose the CPU fan? In fact, when we buy the cooling fan, the general can get the relevant bea

2. process chain and process fan(1) Create process Chain　　① Process Chain : That is, the parent process creates a child process, and the child process that is created creates the child process that belongs to itself again, so that it loops down as shown in turn.　　② key implementations: determines that if the parent process exits , the parent process will only create a child process. if it is a child process, continue to create the next process and th

Tag: no 51ctoIn the game development often need to calculate the fan-shaped field of view or hit range.In fact, this is divided into two parts,The first part is within the fan range (i.e. regardless of the angle, in fact the circle range)The second part is in the fan angle rangeThe first part is very simple, vector3.distance (A, b); calculating distancesHere is t

In fact, this is not familiar with the circuit of the user may not know the internal structure of the chassis, generally bought chassis fan, built-in 3PIN interface, but will bring a large 4PIN transfer wiring. Computer motherboard is a Sysfan interface, generally there are two interfaces are 3PIN interface, if your chassis fan is also 3PIN interface can be directly connected. If it is a large 4PIN, it can

1. Computer power supply fan turn and stop Should be power protection, unplug the power from the motherboard, hard disk, optical drive, video card, and so on the internal components of the connection between, and then to the power supply, with a wire will be the largest power source of a large line of the plug in the Green Line and black line short-circuit, if the power supply is working properly, the focus of the chassis to check the components, The

The most affordable is to repair themselves, the material is very simple, as long as a small piece can aluminum skin and a little butter. 　　Cause of May be the video card fan due to the lack of oil, bearing hole is worn--fan shaft and bearing gap between the too large. Fan in the rotation of the axial movement, and the rotation plane of the blade is also shakin

the fabrication of the fan blades 1. Open Photoshop and create a transparent background document with a width of 10cm, 5cm, and 72ppi resolution. 2. Use the rounded Rectangle tool inside the shape tool (paint only, do not draw path mode, fillet radius 15 or so), and draw a blue-purple rounded rectangle about 9cm long, as shown in Figure 1. Figure 1 Fillet Rectangle 3. Press "Ctrl+t" to pull out the deformation tool, move its deformation center to

1, remove the fan from the chassis, you will find a sticker sticker on the back 2, use tweezers to take down the post. Some fans have stickers on both sides, I do not know which side is the sealing effect, then the two sides are open to see it. 3, uncovered after the bearing is found in which, carefully again see, will find a small stop ring. Many friends may be in this step, they will be injected into the f
