今天我们学习一个方向的概念:上行(Upstream)和下行(Downstream)。 在一个PCIe系统中,方向的定义是以大佬RC为准的。RC高高在上,面往RC方向称之为上行(红色粗箭头),反之称之为下行(蓝色粗箭头)。 由于PCIe是点对点连接的,每个连接的地方,我们称之为Port。对于Root Complex而言,它仅有一个下行端口。对于PCI-Express...
Upstream facing ports 是上游面临的端Downstream facing port是下游面临的端口
Learn the differences and applications of upstream and downstream ports, crucial for understanding modern digital connectivity.
[translate] a有句话说“只有失去之后才懂得珍惜” After has a speech to say “only then loses only then understood treasures” [translate] aIt also forwards the bus traffic between its upstream port and downstream ports. 它也批转公共汽车交通在它的在上游口岸和顺流口岸之间。 [translate] ...
主機USB埠是定義為USB纜線的上行端(Upstream)或「A」接頭,即PC端。而裝置USB埠是定義為USB纜線的下行端(Downstream)或「B」接頭,即行動產品端。 Reference http://www.2cm.com.tw/technologyshow_content.asp?sn=1012210010 A four-port "compact design" USB hub: upstream and downstream ports shown ...
Part Number: XIO3130 i have XIO3130 PCIe,downstream port of PCIe receiving some data from SBC(single board computer).i want to transfer that data from downstream
The apparatus may bind, based on the assignment, the downstream USB port to a first upstream USB port that connects the first physical host device to the display device. The binding may cause the component to be coupled to the first physical host device. The apparatus facilitates assignment of...
aRoot hub acts as a port for the USB device attachment. USB hub provides an extension of connection on the USB system and detects the attachment and detachment of the devices at its ports. It also forwards the bus traffic between its upstream port and downstream ports. 根插孔作为一个口岸为...
The second USB port can then be used as downstream for a low power device (such as a mouse). There is also a MCU on the device that is also connected with USB. The device is also bus powered from the host. Is there any proposed solution for a usb hub that can ...
