At present, our army's informatization construction is dominated by technological revolution, focusing on the development of informatization weapons and equipment, and the core lies in the electronization and computerization of equipment. As the basis of electronic hardware, military chips are known as the "nerve center" of information equipment, which largely determines the combat effectiveness of information weapons and equipment.

Meaning and current situation of military chip

Chip is the general term of semiconductor component products. It is the carrier of integrated circuit (IC). It is divided by wafer. Integrated circuit is a circuit module that integrates a variety of electronic components to achieve a specific function, which undertakes a variety of functions such as operation and storage. The application of integrated circuit covers almost all electronic equipment in military industry and civil industry.

Military chip is a professional integrated circuit used in military field. It is widely used in military computer, navigation, aviation, aerospace, radar, missile and other fields.

The module level basically has the integration capability, and the bottleneck is the high-end military chip at the component level.

Over the past five years, China's annual import of semiconductor chips has reached US $200 billion. China has imported a large amount of semiconductor chips every year. Since 2013, the annual foreign exchange for imported chips has reached more than US $200 billion. In 2017, China imported 377 billion integrated circuits, a year-on-year increase of 10.1%; The import amount was 260.1 billion US dollars, a year-on-year increase of 14.6%.

The research on military chips in China started relatively late. Due to the lack of high-end talents, it is relatively backward in the design of core components, manufacturing equipment and manufacturing technology, and most of them still rely on imports in the field of high-end components.

Reverse + independent two pronged approach, replacing military chips one by one and series by series

The availability of imported chips continues to decline, and module suppliers cut into the core field of components. In the past, military module suppliers usually obtained core components by purchasing foreign commercial chips or obsolete military chips, and based on this, they carried out secondary development and integration to design and complete sub modules to realize specific functions. Due to the decreasing availability of foreign chips and the increasing requirements of military complete machine manufacturers for the localization rate of core components, some module suppliers have cut into the core field of components and invested in the R & D and design of core chips.

Reverse + independent two pronged approach, replacing military chips one by one and series by series. For a long time in the past, the development of military chips in China can only take the reverse design method to realize function imitation on the basis of referring to the functions and interfaces of foreign products, and the technical indexes such as various performance parameters of products can not be completely consistent. Imported devices have been selected in product design. If domestic devices are needed to replace due to shutdown embargo and other reasons, it is often difficult to replace many domestic military chips due to differences or no use experience. The article "Discussion on localization and substitution of electronic components" once made a statistical analysis on the adoption of localization and substitution of electronic components. Only 35% of them can be replaced by domestic ones, and the rest of them can not be replaced due to differences in packaging volume, key performance indicators, no use experience, poor quality reliability and other reasons. At the same time, domestic scientific research institutions have made some breakthroughs in some key areas, such as military CPU, autonomous controllable DSP, military GPU, etc.
