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 […]

Loongson 2H core board is an electronic device computer motherboard that packs the core functions of MINIPC. Most of the core boards are integrated with CPU, storage devices and pins, which are connected with the base plate of supporting facilities according to the pins to complete a system chip in a certain field. People often […]

Hai Hi2115NB-IOT chip: Hi2115 is a system-on-a-chip (SoC) that works at cellular frequency. It uses an on-chip application processor with integrated memory to support small-footprint IoT applications, and can also communicate with external MCU through various digital interfaces. Hi2115 can work in the frequency range of 698~960MHz and 1695~2180MHz, and the system bandwidth is 200kHz. […]

The domestic operating system UOS was officially released not long ago, while the domestic new generation processor was officially released in December 2019. Recently, the official document introduced its product features and new features. As one of the representatives of “China Core”, Loongson released a new generation of general-purpose processors (CPUs) independently developed, which greatly […]

Loongson 1F is realized by SMIC 0.13 micron process and packaged in Wire Bond BGA448. Loongson 1F chip features: Integrated with a GS232 dual-launch Loongson […]

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 […]
