RAWDATA 文件里面只有 32 个浮点数。 写文件的代码 #include <stdio.h> #include <stdlib.h> #define BLOCKMAX 4 #define FRAMEINBLOCK 8 struct rawdata { double frame[FRAMEINBLOCK]; }; int main (){ FILE *outfile; double cache[32]; struct rawdata data_arr[BLOCKMAX]; int *ptr_data_arr; ...
看一个例子,简单了解其用法。 目前没有编译器支持该特性,使用的是https://raw.githubusercontent.com/kokkos/mdspan/single-header/mdspan.hpp实现的版本,所以在experimental下面。 ms2是将数据以二维形式访问,ms3则以三维访问,Views可以改变原有数据,因此最终遍历的结果为: 这个特性值得剖析下其设计,这里不再深究,...
与unique_ptr不同的是,unique_ptr是独占管理权,而shared_ptr则是共享管理权,即多个shared_ptr可以共用同一块关联对象,其内部采用的是引用计数,在拷贝的时候,引用计数+1,而在某个对象退出作用域或者释放的时候,引用计数-1,当引用计数为0的时候,会自动释放其管理的对象。 void fun() { std::shared_ptr<Type> ...

In addition to using intrinsics from C, raw Intel assembly language solutions to this problem are also welcome. The main problem, as others have pointed out, is that the 128-byte data you are checking is missing the data cache and/or theTLBand going to DRAM, which ...

BUFFER 的 RAW DATA 通过 BOUBLE BUFFER 再写到硬盘上, 重放没有问题。 RAW DATA 通过端序转换, 存入数组(SIGNED INT 或者 FLOAT), 存入硬盘文件以后。 通过软件重放, 发现存在高频噪音。(已解决) 缓冲区数据转换成 INT 或 FLOAT 或 DOUBLE,似乎有点问题,有待进一步学习。端序的问题貌似已经理解。 ### C ...
