DDR1 clock problems, DDR1 clock Problems I encountered a problem recently. I had a hard time tossing for a week and had a special crash! When the board is powered on, when reading data from Flash, sometimes an error occurs when writing data to DDR. For occasional errors, it is difficult to use reveal to locate the error online, and the location of each error is not the same. Today, the hardware engineer t

FPGA timing problems and fpga timing problems Recently I made a project ------ 4 1080 p (1920x1080) to synthesize a 4 K (3840x2160,297 M) interface board. When 1080 p goes in and p goes out, the video is played normally. However, when P and 4 K are in progress, the video image will have water ripple. At that time, it was assumed that the timing sequence sent by FPGA to the downstream device SII9136 could no

. Creates a picture object, first looking for the object in the cache, and then fetching the object directly, No, the image resource is found from the bundle, and the object is created and returned. There are no picture resources in the bundle, then nil is returned. Objects created by Imagewithcontentsoffile:magewithcontentsoffile are not cached in system memory. The advantage is that the cache is not generated. Cons: Frequent use of s

Xiao Kee 1. About the initialization of fragmentWhen we set up the interface using the avtivity+fragment combination, we usually have new fragment in the activity, but when we need to pass the parameters in fragment, Are we going to have a problem with the way we use the constructor in the fragment? Yes, we are using the method of construction in the Androidstudio parameter, will be error, simply said: "Fragment in the way the parameter assignment can cause a memory leak problem", the code

/topics/ui/actionbar.html. So you can see that this project is intended to be compatible with the SDK for the lower version number.Workaround:Method one, because this project is to be compatible with the low version of the SDK generated, it is only necessary to create a new project when the minimum version number is selected as Android4.0.Method Two, not in the ADT update to the 22.6.x version number appears after the code, 22.3.x before the version number will not have, good then discard the ne

What should I do if blue screen problems occur in win10 and blue screen problems occur in win10? In win10, have you ever encountered a frequent blue screen situation? This situation is sometimes caused by low computer configuration, and may also be caused by the computer itself. Of course, this can be repaired, let's teach you how to fix it today. First, click the dialog box in the lower-right corner of

Ruby string and array maximization problems, ruby Problems Max Method b=[1,3,55,777,2,4,6,8,0] For numeric data, max obtains the maximum value of the array, and min obtains the minimum value of the array. b.max => 777b.min => 0 It has no practical significance for comparing the size of string arrays,The example in ruby is # enum.max -> obj# enum.max { |a, b| block } -> obj#a = %w(albatross dog horse

Definition of A For loop:for (parameter 1; parameter 2; parameter 3), parameter 1 is usually the initialization parameter, parameter 2 is the judgment, Parameter 3 is the operation of the parameter. None of these three parameters is required.Here is to say, the use of parameter 1: such as the following language　　　　　　　　　　　　　　　　int nLine = 0, nList = 0;1. for (nLine = 0; nLine {......;}2. for (; nLine {......;}Here the parameter 1 is already initialized outside the for loop, does it need to be ini

An expression with four variables is used for sortingNow the key is why a must be in front of b the outermost reason is that in order to get the largest number of biscuits to get the biscuits as little as possi
