Silicon Nitride Ceramic:
Silicon nitride is computationally intensive but not very technical, and it has to be repeated many times. With that said, it's obvious how we can use the GPU to increase the speed of our programs. Using the CPU for complex logic control and the GPU for simple but large arithmetic operations can greatly improve the running speed of the program. The general-purpose central processing unit (CPU) chip is the basic component of the information industry and the core device of weaponry. Our country lacks CPU technology and industry with independent intellectual property rights, which not only causes the information industry to be controlled by others, but also makes it difficult for national security to be fully guaranteed. During the "Tenth Five-Year Plan" period, the national "863 Program" began to support independent research and development of CPUs. During the "Eleventh Five-Year Plan" period, the major project of "Core Electronic Devices, High-end General-Purpose Chips and Basic Software Products" ("Core High Base") introduced the CPU achievements of the "863 Plan" into the industry. Starting from the "Twelfth Five-Year Plan", my country has carried out independent research and development of CPU applications and pilots in many fields, and has formed an independent technology and industrial system within a certain range, which can meet the application needs of weapons and equipment, informatization and other fields. However, foreign CPUs have been monopolized for a long time, and it will take some time for my country to independently develop CPU products and mature the market. In this pursuit, the integration of Silicon Nitride Ceramics and Silicon Nitride Ceramic Block can offer immense potential for enhancing the performance and capabilities of CPUs and GPUs, ultimately bolstering our technological independence and national security.
