C/C++语言编程 基于（英蓓特）STM32V100的看门狗程序
This example shows how to update at regulate period the WWDG counter using theEarly Wakeup interrupt (EWI).
The WWDG timeout is set to 262ms, refresh window set to 41h and the EWI isenabled. When the WWDG counter reaches 40h the EWI is generated and in the WWDGISR the counter is refreshed to prevent ...
可编程逻辑 XAPP228 -Virtex器件内的四端口存储器
This application note describes how the existing dual-port block memories in the Spartan™-IIand Virtex™ families can be used as Quad-Port memories. This essentially involves a dataaccess time (halved) versus functionality (doubled) trade-off. The overall bandwidth of the blockmemory in ...
可编程逻辑 XAPP098 - Spartan FPGA低成本、高效率串行配置
This application note shows how to achieve low-cost, efficient serial configuration for Spartan FPGA designs. The approachrecommended here takes advantage of unused resources in a design, thereby reducing the cost, part count, memory size,and board space associated with the serial configuration ci ...
可编程逻辑 Verilog Coding Style for Efficient Digital Design
 
In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All the ...
工控技术 工业系统安全问题和解决办法
Abstract: As industrial control systems (ICSs) have become increasingly connected and use more off-the-shelfcomponents, new vulnerabilities to cyber attacks have emerged. This tutorial looks at three types of ICSs:programmable logic controllers (PLCs), supervisory control and data acquisition (SCA ...
测试测量 DN427开关控制器故障保护电压监测
 
Have you had the exasperating experience of a laptop orPDA defi antly not responding to your commands? Youfrantically press key after key, but to no avail. As hopeturns to anger (but just before you throw the company’slaptop through the window) you slam your fi nger againstthe on/of ...

人工智能/神经网络 The Hopfield model is a distributed model of an associative memory. Neurons are pixels and can take
The Hopfield model is a distributed model of an associative memory. Neurons are pixels and can take the values of -1 (off) or +1 (on). The network has stored a certain number of pixel patterns. During a retrieval phase, the network is started with some initial configuration and the network dynamics ...
