Domestic high-end chips [Weikewei]]

What is a high-end chip? There is no strict definition or unified statement for this internationally. Nowadays, people generally refer to chips as circuits integrated on silicon blocks. So high-end chips generally refer to digital logic circuits or specialized circuits that have a qualitative leap on the basis of ordinary chips, with higher integration, faster speed, stronger functions, and even on-site programming. Modern weapons and equipment have widely adopted various chips since the 1990s.

It is a memory structure that separates program instruction storage and data storage. It has an independent address bus and an independent data bus, which are shared by program memory and data memory in a time-sharing manner. This also overcomes the bottleneck of data stream transmission and greatly improves the computing speed.

Taking the F-35, the fifth generation fighter jet of the United States, as an example, it is known as the world's first fighter jet designed entirely according to the requirements of information warfare, as it can achieve "seamless compatibility" with the current combat system of the US military. During combat, the F-35 exists as a node in information warfare. The design purpose of the integrated electronic warfare system equipped on board is to maximize the pilot's perception of the entire battlefield situation; Its single machine electronic warfare capability can even reach the performance of professional electronic fighter jets.

58彩票 The main task of electronic devices in modern weapon systems is to receive information, process and quickly calculate it, and output instructions to control the executing components. Taking modern radar as an example, its data rate is as high as tens of times per second, which means it needs to complete one operation in just a few tenths of a second. Therefore, information processing chips are required to have real-time, fast, and high-capacity computing capabilities. The most commonly used algorithms currently are convolution and Fourier transform.
