Data transfer from GPIO port to RAM buffer using DMA upon receiving a trigger signal on the timer capture input channel. Our requirement is to configure the DMA so that it transfers data from the GPIO lines (8 bit data lines) to the RAM buffer upon r…

AN2548 -- 使用 STM32F101xx 和 STM32F103xx 的 DMA 控制器 DMA控制器 DMA是AMBA的先进高性能总线(AHB)上的设备,它有2个AHB端口: 一个是从端口,用于配置DMA,另一个是主端口,使得DMA可以在不同的从设备之间传输数据. DMA的作用是在没有Cortex-M3核心的干预下,在后台完成数据传输. 在传输数据的过程中,主处理器可以执行其它任务,只有在整个数据块传输结束后, 需要处理这些数据时才会中断主处理器的操作. 它可以在对系统性能产生较小影响…

原文:https://www.ibm.com/developerworks/library/j-zerocopy/ <Efficient data transfer through zero copy> 本文描述通过一种叫做Zore Copy的技术来提升运行在Linux和UNIX上的Java程序的IO性能. Zero copy避免冗余的数据拷贝并减少用户态和内核态之间的上下文切换. 很多WEB应用都服务大量的静态文件,这些静态文件大多从磁盘读取并返回到socket中.这些操作需要相对较少的CP…

BACKGROUND Embodiments of this invention relate to RDMA (remote direct memory access) data transfer in a virtual environment. Traditional RDMA allows data to move directly from the memory of one computer into that of another without involving either…

BACKGROUND OF THE INVENTION The present invention relates to data transfer across domains, and more particularly, to data transfer across a number of different protection domains using page remapping. Operating systems that utilize different protecti…

There are four data transfer types defined in USB(USB中有4种数据传输类型). Each type is optimized to match the service requirements between the client software and the USB device. The four types are: Interrupt Transfers(中断传输) - Small data transfers used to co…

Data transfer object (DTO) is a design pattern used to transfer data between software application subsystems. DTOs are often used in conjunction with data access objects to retrieve data from a database. The difference between data transfer objects a…
