2007年8月1日 · The aim of the study was to synthesize and characterize an isophorone-based urethane dimethacrylate (IP-UDMA) resin-monomer and to investigate its shrinkage and curing kinetics.

2022年3月23日 · 本文是关于XDMA ip的使用详解，主要从ip的设置与使用两方面介绍。 包括： XDMA 的 IP 设置； XDMA 的 IP 参数选择；中断情况；例程模式；实际实例等方面。

The CORE-V-MCU’s micro-DMA (uDMA), is an intelligent, lightweight and completely autonomous Direct Memory Access controller capable of handling complex I/O schemes. Its primary purpose is to reduce the CPU overhead used to control I/O peripherals.

udma uart The uDMA Universal Asynchronous Recevier Transmiter supports most standard options for UART Tx/Rx. It has a configurable number of data bits from 5 to 8, a configurable number of stop bits(1 or 2) and can add a parity bit at the end of data bits in case of a transmission or check the parity bit in case of a reception.

2022年5月3日 · 本文详细介绍了PCIe的基础知识，包括数据链路与拓扑结构，以及Xilinx 7Series FPGA中PCIe IP核的配置和使用。 内容涵盖配置参数、DMA引擎、BAR映射、描述符设置和传输过程。

IP中涉及的接口： AXI-MM接口，用于高性能、大带宽的数据传输; AXI4-Stream 接口适用于低延迟数据流传输; AXI Lite Master 接口，是简化版的 AXI 接口，用于较少数据量的通信，一般多用于配置外设寄存器等轻量级的数据传输场景。 DMA bypass就是普通的PCIE传输。

• UDMA-C (Controller) – Triggers request and receives response from UTC (Channel controller), DRU, PDMA • UTC (Unified Transfer Controller) – Received Transfer Request from UDMA and performs actual transfers (Transfer Controller) • DRU (Data Routing Unit) – Special UTC for high performance data movement esp meant for C7x algorithms

Ultra DMA的英文拼写为“Ultra Direct Memory Access”，一般简写为UDMA，含义是超直接存储器存取 。 UDMA模式 采用16-bit Multi-Word DMA（16位多字节DMA）模式为基准，可以理解为 DMA模式 的增强版本，它在包含了DMA模式的优点的基础上，又增加了CRC（Cyclic Redundancy Check， 循环冗余码校验）技术，提高 数据传输 过程中的准确性，安全性得到保障。 在以往的硬盘 数据传输 模式下，一个 时钟周期 只传输一次数据，而在 UDMA模式 中逐渐应用了Double …

Objectives: The aim of the study was to synthesize and characterize an isophorone-based urethane dimethacrylate (IP-UDMA) resin-monomer and to investigate its shrinkage and curing kinetics. Methods: The IP-UDMA monomer was synthesized through the reaction of polyethylene glycol 400 and isophorone diisocyanate followed by reacting with HEMA to ...

Using the uDMA I2C master involves writting the appropriate sequence of commands to the Tx buffer, and using the uDMA to send the buffer to the I2C contoller. A list of the available commands and their encoding is shown in the Table below.
