dma Dynamic Memory Allocation 动态内存分配 Explanation: 为了解决上述问题,C++ 提供了一种“动态内存分配”机制,使得程序可以在运行期间,根据实际需要,要求操作系统临时分配一片内存空间用于存放数据。此种内存分配是在程序运行中进行的,而不是在编译时就确定的,因此称为“动态内存分配”。 http://c.biancheng.net/view/206.html -------------------------------------------------- Note added at 1 day 13 hrs (2021-03-06 07:09:01 GMT) -------------------------------------------------- Dynamic memory allocation (DMA) in C Programming https://www.programtopia.net/c-programming/docs/dynamic-memo... 也可能是:Direct Memory Access,直接内存存取 / 直接存储器存取 / 直接内存访问 https://en.wikipedia.org/wiki/Direct_memory_access |

dma 直接内存存取 Explanation: 应该是直接内存存取,即direct memory access。 DMA(Direct Memory Access,直接内存存取) 是所有现代电脑的重要特色,它允许不同速度的硬件装置来沟通,而不需要依赖于 CPU 的大量中断负载。否则,CPU 需要从来源把每一片段的资料复制到暂存器,然后把它们再次写回到新的地方。在这个时间中,CPU 对于其他的工作来说就无法使用。 Example sentence(s):
