“Open Source Godson Motherboard” is a Godson embedded motherboard developed by Godson Club and Godson in an open source way. It integrates Godson 1CSOC, network port, USB port, power supply, SD card slot, RTC clock and other main components on a small circuit board with the same specifications as “Raspberry Pi”. It can run embedded […]

Loongson (English: Loongson, formerly known as GODSON) is a general CPU designed by Hu Weiwu, Institute of Computing Technology, Chinese Academy of Sciences, etc. It adopts MIPS and LoongISA® reduced instruction set architecture, and buys out the MIPS instruction set patent. Godson-1 series are embedded domain chips, which have been used by many enterprises. The […]

1. Brief introduction, blind holes and embedded fillers are mainly made of high-density and small microplates. Purpose depends on saving circuit space, so as to reduce PCB volume, such as mobile phone board. Second, classification: 1). Laser drilling, 1. the reason for drilling with laser: a. customer data requires drilling with laser; B because the […]

Loongson Zhongke released ——2K1000, the smallest industrial system solution produced in China, which is suitable for application scenarios such as Internet of Things and independent controllable industrial security system. In this scheme, the domestic Godson 2K1000 processor is adopted, the surface-mounted DDR3 2GB domestic memory is used, the maximum surface-mounted 2GB NAND FLASH is stored, […]

The introduction of Loongson 3A2000 processor, which is “Loongson 3A3000/3B3000 is the latest upgraded product of Loongson 3 series processors. Based on the design of Loongson 3A2000, Loongson 3A3000 has made a few structural improvements, such as increasing the number of key queue entries of processor cores, expanding on-chip private/shared cache capacity, etc., which is […]

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 […]
