2024年5月16日 · AXI UART 16550是 Xilinx FPGA中提供的一个 UART IP核，它允许通过AXI接口与UART设备进行通信。 本文描述了如何使用Xilinx的Vivado Design Suite环境中的工具来定制和生成 UART 16550 IP核，以及如何配置和使用该IP核。 以下是针对如何定制IP核的步骤的简要概述： （1）打开或新建一个工程。 （2）如下图所示，找到UART 16550 IP核。 （3） 双击IP，或从工具栏或右键菜单中选择“Customize IP”命令，打开该IP核的配置页。 在AXI UART 16550 Vivado …

Programmable Communications Interface: 16550. A universal asynchronous receiver/transmitter (UART). Operation speed: 0-1.5M Baud (Baud is # of bits transmitted/sec, including start, stop, data and parity). Includes: A programmable Baud rate generator. Separate FIFO buffers for input and and output data (16 bytes each). Asychronous serial data:

The 16550 UART consists of five interconnected entities (see fig. 5): transmitter, receiver, modem interface, bau- drate generator and interrupt controller. This structure is reflected in the...

Examine the upper schematic, 74138 Addressing Scheme. There are 12 registers in the UART as shown left in 2 charts (16550 UART Register Selection, UART Register to Port Conversion Table). Both charts indicate the port value to be added to your base IO address for the device. Example: we used $00 as the base address for the 8255 PPI.

Register level and functionality compatibility with NS16550A (but not 16450). Debug Interface in 32-bit data bus mode. Optional baud rate output signal. The signal here is the 16 x actual baud rate. Due to the 16-bit clock divider 1258Mhz is the maximum frequency if the minimum bps required is 1200.

This UART core is very similar in operation to the standard 16550 UART chip with the main exception being that only the FIFO mode is supported. The scratch register is removed, as it serves no purpose. This core can operate in 8-bit data bus mode or in 32-bit bus mode, which is now the default mode.

Programmable Communications Interface: 16550 The 16550 can control a modem through DSR, DTR, CTS, RTS, RI and DCD. In this context, the modem is called the data set while the 16550 is called the data terminal .

The UART_16550 IP is a Universal Asynchronous Receiver Transmitter module fully compatible with the de-facto standard 16550. This is the standard that can be found in most personal computers and for which a lot of software knowledge and programs is available.

2024年10月29日 · axi-uart16550是Xilinx的一款串口IP核，支持配置成16450或16550模式，16550和16450是指的早期电脑主板上的串口芯片型号，16550相比于16450多了FIFO，现在已经很少使用。

Core16550 is a standard UART providing software compatibility with the popular 16550 device. It performs serial-to-parallel conversion on data originating from modems or other serial devices, and performs parallel-to-serial conversion on data from a CPU to these devices.
