Portable computer mainboard based on SW 421 processor

Abstract

The invention particularly relates to a portable computer mainboard based on a SW 421 processor. According to the portable computer mainboard based on the SW 421 processor, the SW 421 processor is adopted, the SW 421 processor is connected through a PCI-E expansion bridge piece, PCI-E resource expansion is achieved, and a USB3.0 interface, an Ethernet interface, an audio interface, a serial port, an M.2 interface, a display interface, a lithium battery interface and a keyboard and mouse interface are externally provided. The portable computer mainboard based on the SW 421 processor is autonomous, controllable, safe and available, promotes the localization process of computer products, and further guarantees network information security and industrial control security.

Description

technical field [0001] The invention relates to the technical field of domestic computers, in particular to a mainboard of a portable computer based on the Shenwei 421 processor. Background technique [0002] The current situation in the field of information security is not optimistic, and the computer localization market has broad prospects. In recent years, various security incidents have emerged one after another. Network information security and industrial control security have now risen to the status of national strategic security, seriously threatening national security. The development of independent and controllable information security technology in the future is a strategic goal related to national security, and it has become a consensus that localized computer application technology is the top priority of information technology. [0003] In this situation, the importance of domestic chip development and independent innovation has become increasingly prominent. T...

Problems solved by technology

[0004] However, due to the short development time of domestic independent processors, the software and hardware ecological environment is not perfect, there are few open source materials that can be used for reference, and the promotion and application of domestic independent controllable computers is relatively slow.
