A poll message is a control-acknowledgment message.. In a multidrop line arrangement (a central computer and different terminals in which the terminals share a single communication line to and from the computer), the system uses a master/slave polling arrangement whereby the central computer sends message (called polling message) to a specific terminal on the outgoing line.
The Data Plane Development Kit (DPDK) is an open source software project managed by the Linux Foundation.It provides a set of data plane libraries and network interface controller polling-mode drivers for offloading TCP packet processing from the operating system kernel to processes running in user space.
Both PS/2 and USB allow the sample rate to be overridden, with PS/2 supporting a sampling rate of up to 200 Hz [5] and USB supporting a polling rate up to 1 kHz [3] as long as the USB mouse runs at full-speed or higher USB speeds.
The maximum signaling rate in USB 2.0 is 480 Mbit/s (60 MB/s) per controller and is shared amongst all attached devices. Some personal computer chipset manufacturers overcome this bottleneck by providing multiple USB 2.0 controllers within the southbridge.
The xHCI reduces the need for periodic device polling by allowing a USB 3.0 or later device to notify the host controller when it has data available to read, and moves the management of polling USB 2.0 and 1.1 devices that use interrupt transactions from the CPU-driven USB driver to the USB host controller.
The Poll Police have sifted through their archives and have come up with five potential namings of their latest criminal -- the new Sixaxis controller featuring Immersion's TouchSense technology ...
This DMA controller uses the UART's DMA mode signals that were defined for the 16550. The DMA controller requires the CPU to set up each transaction and poll a status register after the transaction is started to determine if the transaction is done. Each DMA transaction can transfer between 1 and 128 bytes between a memory buffer and the UART.
Democratic U.S. Rep. Mary Peltola’s 2022 victory in Alaska has served as a bogeyman for opponents of ranked choice voting. How could a Democrat wind up winning in a deeply red state?
