Integer fast multiplication/fast Power + matrix fast power +strassen algorithm

The fast power algorithm can be said to be a kind of ACM competition is necessary, and is also a very basic type of algorithm, given that I have been learning more fragmented, so today with this post summed upFast multiplication usually has two types of applications: First, integer operation, calculation (A*B) mod C second, matrix fast multiplicationinteger operations: (Fast multiplication, fast power)Let's

Failure analysis of automatic power-on on a power supply

"Fault phenomenon" a computer recently connected to the power on its own boot, sometimes inexplicably on the boot. "Failure analysis and processing" causes this kind of failure may have the following: (1) First check whether the computer in the BIOS setup will be timed to boot function set to "Enabled", so that the computer in the set time automatically boot. (2) Again check whether the computer in the BIOS setup item to open the function of the call

5G technology, the power consumption and cost problems of far-reaching optical power supply are enough for it to drink a pot, 5g a pot 5G is getting closer and closer, but not all places have it, and it will not be abrupt. The first version that comes to people's eyes is not the fastest version of the technology. In reality, 5G is the first to show in a densely populated metropolis. Since 2020 or 2021, 5g

Geometric artboard power output power function image how to make?

function image of power output power of geometric artboard How to make ? First of all, to understand the power output power and the relationship between the external resistance: set the power of the electromotive force is e, internal resistance is r, outside the resistance

Pay attention to the design of power supply fan when purchasing computer power

Chassis power supply as a source of computer energy, its importance is more and more people pay attention to, but, the importance of power supply fan is still neglected by most consumers. As a result, a sudden increase in the noise of the power supply fan has occurred. The reason is that because the fan is running all the year round, the fan blade and the fan's e

Master LU 2015 Intelligent Power saving and total power saving how to set

What are the differences between intelligent power saving and total power saving in Master LU 2015 Intelligent Power Saving: The use of computer idle time, Master LU detected the computer temperature is too high to start cooling program. Intelligent power saving does not affect the speed of the system. (It is recommen

Principle of switching power supply and Design of series-connected Switching Power Supply for Energy Storage filtering inductance (III)

1-2-3. Calculation of energy storage filter inductance of tandem Switching Power SupplyFrom the above analysis, we can see that the output voltage of the tandem switch power supply is related to the duty cycle D of the control switch and the energy storage inductance L, because the energy storage inductance L determines the current rise rate (DI/dt), that is, the output current size. Therefore, it is import

Power-on and power-supply of DSP6000

1. DSP6000 power-on sequence Problems DSP is indeed a freak. Two common problems are: (1) unable to connect to the CCS development environment; (2) burning chips. I am using TMS320C6713 now. The following experiences are based on DSP6000. Other series may be different. It seems that the performance of the chip has changed, and the chip has never been burned. However, CCS still often cannot be connected. Some of the reasons are related to the stability
