Demultiplexing-200-MHz-Data-Streams.rar - Modern serial data protocols (e.g.,
FireWire, SONET, ATM, T4) sometimes require
clocks that are faster than maximum FPGA
global clock speeds. To solve this problem,
the incoming clock (200 MHz in the example
below) can be used to demultiplex the incoming
single data stream into two parallel data
streams clocked at one-half the speed (100
MHz here),2016-04-16 22:15:17,下载1次

PC-Fan-Control-using-ATtiny13.zip - PC Fan Control using ATtiny13...
This application note describes the operation of 12 volt DC cooling fans typically
used to supply cooling air to electronic equipment: These fans are typically based
on two-phase Brushless DC (BLDC) motors drawing between 1 and 50 watts of
power. Single-phase brushless DC motors are also used in fans, but this is outside
the scope of this application note.
Further discussion describes the addition of an Atmel ATtiny13 microcontroller and
the benefits this offers, such as variable speed by external thermistor input. An
additional input is a PWM pulse width-varying signal, which also controls fan
speed.,2012-12-11 18:44:00,下载10次

vga2pal_ntsc.zip - VGA to PAL and NTSC converter...
This circuit is based on AD722 IC from Analog Devices. The AD722 is a low cost RGB to NTSC/PAL Encoder that converts red, green and blue color component signals into their corresponding luminance (baseband amplitude) and chrominance (subcarrier amplitude and phase) signals in accordance with either NTSC or PAL standards. These two outputs are also combined to provide composite video output. All the outputs can drive standard 75 ohm terminated video cables directly without extra amplifiers. The chip is a very compact solution, because operates from a single +5 V supply and it need no external delay lines or filters. ,2012-12-11 17:57:19,下载15次
Takagi-Sugeno-fuzzymodel.rar - The fuzzy inference process discussed so far is Mamdani s fuzzy inference method, the most common methodology. This section discusses the so-called Sugeno, or Takagi-Sugeno-Kang, method of fuzzy inference. Introduced in 1985, it is similar to the Mamdani method in many respects. The first two parts of the fuzzy inference process, fuzzifying the inputs and applying the fuzzy operator, are exactly the same. The main difference between Mamdani and Sugeno is that the Sugeno output membership functions are either linear or constant.,2011-02-05 00:46:12,下载36次

crc-algorithm.rar - The cyclic redundancy check, or CRC, is a technique for detecting errors in digital
data, but not for making corrections when errors are detected. It is used primarily
in data transmission. In the CRC method, a certain number of check bits, often
called a checksum, are appended to the message being transmitted. The receiver
can determine whether or not the check bits agree with the data, to ascertain with
a certain degree of probability whether or not an error occurred in transmission. If
an error occurred, the receiver sends a “negative acknowledgement” (NAK) back
to the sender, requesting that the message be retransmitted,2010-12-29 23:03:17,下载4次

USBtoUART_protocol_converter.zip - The USB interface has become extremely popular, due to its simplicity for end user
applications (Plug and Play without restart). For developers, however, USB
implementation into their devices has been more complicated when compared to
e.g. RS232. In addition there is a need for device drivers as software support on
the PC side. Because of this, RS232 based communication is still very popular
among device manufacturers. This interface is well established and has good
operating system support, but recently the physical RS232 port has been removed
from the standard PC interface, giving ground to USB ports.,2009-11-18 23:30:39,下载1次
