50d memory card

Today, I tried to implement FFT using cuda, and encountered a problem. If you call the cufft library directly, the memory copy-to-data processing time is about. However, it is said that cufft is not the most efficient, so I want to exercise it myself. My idea is to map each row of two-dimensional data to a block, and each vertex is a thread. First, copy the data to the global memory of the video

Android-system information (memory, cpu, SD card, power, Version)The total memory size of memory (ram) android is stored in the system's/proc/meminfo file. You can read this file to obtain this information: copy the code public void getTotalMemory () {String str1 = "/proc/meminfo"; String str2 = ""; try {FileReader fr

This is a relatively simple problem, but also we often back to the problem, that is, in the development process of Android, how to transfer memory card pictures or other files, and then processing this file, because we can not process the original file, is currently doing a picture of the Android project, So use this knowledge, and share it with you.private void String2file () {tempfiles = new file[resultfi

Android transfers images or other files in the memory card to another path. This is a simple problem, but it is also a problem we often encounter, that is, how to store images or other files on the memory card during Android development, then we can process this file. Because we cannot process the original file, we are

For example, Echo Number_format (285266237); Can output 285,266,237 In addition, if you need to format the size of the file byte, the following methods can be drawn: function Byte_format ($input, $dec =0) { $prefix _arr = Array (' B ', ' K ', ' M ', ' G ', ' T '); $value = Round ($input, $DEC); $i = 0; while ($value >1024) { $value/= 1024; $i + +; } $return _str = Round ($value, $dec). $prefix _arr[$i]; return $return _str; } echo Byte_format (285266237); Display result is 272M For example, Echo

When a user uses a USB flash drive, the USB flash drive is suddenly unplugged, or the USB flash drive is temporarily paralyzed due to power failure. When another machine is inserted into the USB flash drive, the "disk I: not formatted" prompt or the USB flash drive cannot be opened, you need to format the USB flash disk.
