Latency: is the amount of time that data (a message or packet, or even a bit) is transferred from one segment of the network or link to the other.
Send delay : Is the time taken from the first bit of the sending data frame to the last bit of the frame to be sent.
Transmit delay = data frame Length (b)/channel bandwidth (S/b) [channel bandwidth is data rate]

Delaytime:The duration of the response is milliseconds (milli-second, 1‰ seconds.
Feedback:It is just a few voices (for example, more and more voices), and the larger the set, the more sounds.
Effectlevel:When the original sound pops up, the greater the tlevel, the larger the volume of the first delay sound, the lower the second voice, and the lower the third voice. So if the tlevel is set to small, you will only hear the delayed sounds after the orig
There are no empty statements in the standard C language. But in the MCU programming of C language, it is often necessary to use a few empty instructions to produce short delay effect. This is easy to achieve in assembly language, write a few nop on the line.In Keil C51, call the library function directly:#include//declared void _nop_ (void);_nop_ (); Produce a NOP instructionFunction: For the delay is very

Sensor captures motion input data
The collected data is filtered and transmitted to the host via a cable
Game engine updates logic and render viewports based on acquired input dat

system (this problem is not clear yet), so I used tcpdump to capture packets and analyze it, after the server backend returns the response packet, the client does not immediately confirm the ACK of the data, but waits for nearly 40 milliseconds to confirm. After Google, and read "TCP/IP details 1: Protocol", it is known that TCP Delay confirmation (delayedACK) mechanism.
The solution is as follows: after calling the Recv system, call the setsockopt f
Precise delay of c51Some friends suggested that the accuracy of 51 Single-Chip Microcomputer delay program using C language is not enough. In fact, the C language is eventually compiled into an assembly language for running, so the assembly program will be very large, this affects the precision of latency. Here, we will post some online materials for your reference.The following content is reprinted:A Simpl

The effect of this feature is that if a user enters an incorrect password to try to log in, the time of the authentication before each logon increases as the number of login errors increases, slowing down the possibility of a password attempt to attack the database repeatedly.Howe

The C language code below uses a function that generates random numbers, and a delay function. Please carefully observe its display effect.
From the following code, we can draw an important conclusion: when the above two kinds of functions are put into the loop, we should make some changes. Also focus on the definition of its parameters (outside of the child function?). Inside the child function? Global variable? Local variables? )。
