A language monitor provides a full duplex communications path between the print spooler and bi-directional printers that are capable of providing software-accessible status information and adds printer control information, such as commands defined by a printer job language, to the data stream s.

本例展示了如何实现2个SPI之间的在全双工（full-duplex）模式下通信，通过NSS软件管理，实现了由主向从，接着又从向主发送数据。 在本例程中，设置SPI1和SPI2为8bit数据帧，9Mbit/s传输速率。 在第一阶段，由主SPI1把SPI1_Buffer_Tx发送到SPI2，由从SPI2把SPI2_Buffer_Tx发送到SPI1。传输完成后，通过比较判断传输是否正确。 由于NSS管脚由软件管理，因此，可以在不改变硬件配置的情况下使SPI1由主变从，而SPI2由从变主。在第二阶段，由从SPI1把SPI1_Buffer_Tx发送到SPI2，由主SPI2把SPI2_Buffer_Tx发送到SPI1。传输完成后，通过比较判断传输是否正确。 在STM3210B-LK1上，如果以上4个传输都正确，则亮起LED1（LD4），否则亮起LED2（LD3）。

The recent developments in full duplex (FD) commu- nication promise doubling the capacity of cellular networks using self interference cancellation (SIC) techniques. FD small cells with device-to-device (D2D) communication links could achieve the expected capacity of the future cellular networks (5G). In this work, we consider joint scheduling and dynamic power algorithm (DPA) for a single cell FD small cell network with D2D links (D2DLs). We formulate the optimal user selection and power control as a non-linear programming (NLP) optimization problem to get the optimal user scheduling and transmission power in a given TTI. Our numerical results show that using DPA gives better overall throughput performance than full power transmission algorithm (FPA). Also, simultaneous transmissions (combination of uplink (UL), downlink (DL), and D2D occur 80% of the time thereby increasing the spectral efficiency and network capacity

The LPC1700 Ethernet block contains a full featured 10 Mbps or 100 Mbps Ethernet MAC (Media Access Controller) designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control frames, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity. Automatic frame transmission and reception with Scatter-Gather DMA off-loads many operations from the CPU.
