There are two kinds of SRAM in Loongson chip: one is CPUSRAM； which is closely related to microprocessor (data, code memory); The other is HDCSRAM used for hard disk control, which can’t be read directly by microcontroller, and is a dual-port SRAM. Both of them choose different testing strategies. Test strategy of CPUSRAM Like the […]

The chips designed by HiSilicon cover a wide range, including wifi networks, fixed networks, digital media and other fields, but the most concerned and highly concerned ones are processor chips, including mobile phone processor SoC, server chips and its AI chips. On the technical level and threshold, the mobile phone with processor is obviously the […]

In order to improve and ensure the high-quality welding of electronic circuits, and prevent false welding and virtual welding in circuit welding, it is the key to correctly operate the soldering iron and reasonably select soldering tin and flux, and the treatment of the lead pins of the electronic components to be welded, the proper […]

PCB design is very important for power circuit design, and it is also one of the necessary technologies for beginners. In this article, Xiaobian will share some highlights about PCB design. PCB structure design In this step, according to the determined circuit board size and various mechanical positioning, the PCB board surface is drawn in […]

Domestic Feiteng has reached the level of international mainstream processors a few years ago. When Feiteng 2000 appeared, the opportunity of Feiteng appeared. Without a strong software background, the development of domestic cpu is slow, and it is impossible to develop effectively for a long time. It is very difficult to rely on China’s current […]

As a domestic self-developed processor, Loongson is not easy to develop with backward technology and investment. The biggest question from the outside world is where Loongson is used. To solve this problem, Loongson recently participated in 2019 China International Finance Exhibition and Shenzhen International Finance Expo, and introduced the specific application of Loongson processor in […]
