Although inChipsIn terms of process technology, China lags behind the United States by several generations, but inMilitaryIn the field, most of China's performance has surpassed that of the United States. This is especially evident in various types of military equipment. Advanced military drones,Fighters, missiles, rocket artillery,Navycombat ships, etc., these equipment have surpassed those of the United States. Even RussianMilitaryExpert Vasily Kashin said that the ChineseMilitaryThe strength has already surpassed Russia to become the second in the worldMilitaryPower.
For this phenomenon, we can't help but think about why ChinaMilitaryEquipped inChipsIn the case of backward technology, it can still surpass the United States?The answer is actually quite simple, that isrequired for the deviceChipsIt's not that the more advanced the better, but that it's enough. On the contrary, the more advancedChipsThe worse the anti-interference ability, the less stable it isChips
First of all, we need to recognize that in:In the equipment, the general comprehensive computing power usedChips(e.g. CPU, .)socRelatively few, more professional is usedChips(Such as.)asicfpga、assp）。Because forEquipment, there is no need to perform complex calculations, but to focus on executing specific instructions. Therefore,ChipsIt does not need to have a strong comprehensive computing power, but only needs to stably execute its specified instructions. Therefore,asicfpga, ASSP and other majorsChipsMore applicable. These professionsChipsSimple and mature, the process requirements are low, even the 130nm process is enough to use, and the operation is stable.
In addition, we can pass through the Russian oneequipment to observe this. RussianMany of them are basically not used in modern generalsChips, but adoptTubesand other old-fashioned components. Despite this, these pieces of equipment are known for their outstanding performance. This shows that inEquipped,ChipsCraftsmanship is not the most important factor. In practice, area, power consumption and cost are not decisive factors. If we really need to pursue high performance, we can do it with a mature processChipsThe area is enlarged, and the heaps are moreTransistorsto achieve the required high performance.
Second, we need to recognize the difference between advanced and mature processes. Compared with mature technology, advanced technology is mainly reflected in:TransistorsHigher density, lower power consumption, smaller area, lower cost, etc. However, inIn equipment, these factors are not the most critical. If you don't take into account the cost,ChipsUnder the premise of area and power consumption, we can manufacture the same performance as the advanced process under the mature processChips, only the area and power consumption will be larger. Therefore,ChipsThe advanced technology is not the decisionAdvanced key factors. Otherwise, thoseChipsTechnologically backward countries, in modern warfareLieutenant GeneralUnsustainableMilitaryStrength.
To sum up, despite the fact that China is inChipstechnologically lagging behind the United States, but itsMilitaryThe main reason why the performance surpasses the American is the specialization required for the equipmentChipsStable enough and capable of executing specific instructions. WhileChipsThe sophistication of the process is not the decisive factor. EspeciallyIn equipment, area, power consumption and cost are not the most important, on the contrary, stable and reliable execution ability is the key. Thus, China is able to:ChipsAchieved in the case of backward technologyMilitaryEquipping superiority, this is indeed a remarkable achievement.
In modern timesMilitaryEquipped,ChipsTechnology plays an indispensable role, despite the combined computing powerChipsInThere are relatively few applications in equipment, butChipsAs an important part of the overall system, for:Gear provides powerful calculations, control, andCommunicationsAbility. Let's take a look at the different types of majorsChipsIn modern timesMilitaryApplications in equipment.
asic(applicationspecificintegratedcircuit): dedicatedIntegrated circuits
asicIt is tailor-made for specific applicationsChips, with specific functions and specific structures, are mainly used to perform specific tasks. InMilitaryEquipped,asicChipsIt is widely used in:Radar, missile guidance system,Communication systemsand other key areas. The advantages are low power consumption, high speed, reliability, and a high degree of customization to meet the needs of a wide range of complex tasks.
Take, for example, modernFightersThe anti-aircraft missile launch system in the case was specially designedasicChips。theseChipsIt has high speedData Processingcapabilities, capable of obtaining target information in real time, calculating rocket launch trajectories, and conducting automatic guidance. Due to the function sheet.

3. ASSP (ApplicationSpecificStandard Product): Standard products for specific applications.
ASSP is a class of pre-designed applications for specific applicationsChips, with specific features andinterface。InMilitaryEquipped, asspChipsIt is mainly used in control systemsSensorsetc. The advantages are low cost, reliability, and the ability to provide the required requirements for specific applicationsinterfaceand features.
For example, a control system on a modern ** uses multiple controllersChipstheseChipsIt is designed specifically to control different subsystems, such as missile systemsRadarsystem, etc. Due toChipsSpecificity of function, ASSPChipsIt can better meet the specific requirements of each subsystem, and has a high degree of stability and reliability.
To sum up, there are different types of majorsChipsIn modern timesMilitaryequipment plays an important role. Either wayasicfpgaOr asspChips, they are all forMilitaryGear provides powerful calculations, control, andCommunicationsAbility. theseChipsIt is characterized by functional specialization.
