Hard precision company substrate series chips are designed and developed by Zhongke Technology Co., Ltd., Chinese Academy of Sciences. They adopt MIPS architecture and have independent intellectual property rights. The products now include Godson No. 1 small CPU, Godson No. 2 medium CPU Zirconia Ceramic Sleeve and Godson No. 3 large CPU three A series, in addition to the Godson 7A1000 bridge. Loongson No. 1 series 32/64-bit processors are specially designed for the embedded field, mainly used in cloud terminals, industrial control, data acquisition, handheld terminals, network security, consumer electronics and other fields, with low power consumption, high integration and high cost-effective features. Among them, the Loongson 1A 32-bit processor and the Loongson 1C 64-bit processor work stably at 266-300 MHz, and the Loongson 1B processor is a lightweight 32-bit chip. The Loongson 1D processor is a dedicated chip for ultrasonic heat meters, water meters and gas meters. In 2015, the new generation of Beidou navigation satellites was equipped with the Loongson 1E and 1F chips independently developed by my country. These two chips are mainly used to complete the data processing task of the inter-satellite link. The Loongson 2 series are 64-bit high-performance low-power processors for desktop and high-end embedded applications. Loongson 2 products include Loongson 2E, 2F, 2H and 2K1000 chips. For the first time, the Loongson 2E has achieved external production and sales authorization. The average performance of Loongson 2F is more than 20% higher than that of Zirconia Ceramic Sleeve Loongson 2E, and it can be used in personal computers, industrial terminals, industrial control, data acquisition, network security and other fields. The Loongson 2H was officially launched in 2012, which is suitable for the needs of computer, cloud terminal, network equipment, consumer electronics and other fields, and can be used as a full-featured chip with HT or PCI-e interface. In 2018, Loongson launched the Loongson 2K1000 processor, which is mainly a dual-core processing chip for the field of network security and mobile intelligence. The main frequency can reach 1 GHz, which can meet the needs of the rapid development of the Industrial Internet of Things and the needs of an autonomous and controllable industrial security system.
The Loongson 3 series are multi-core processors for high-performance computers, servers and high-end desktop applications, featuring high bandwidth, high performance and low power consumption. The Loongson 3A3000/3B3000 processor adopts an independent microstructure design, and the main frequency can reach more than 1.5 GHz; the Loongson 3A4000, which is planned to be market-oriented in 2019, is the first quad-core chip of Loongson's third-generation products. The chip is based on the 28nm process and adopts new research and development GS464V 64-bit high-performance processor core architecture, and implements 256-bit vector instructions, while optimizing on-chip interconnect and memory access paths, integrated 64-bit DDR3/4 memory controller, integrated on-chip security mechanism, frequency and performance will be Zirconia Ceramic Sleeve Greatly improved again.

The Loongson 7A1000 bridge chip is the first dedicated bridge chip set product of Loongson. The goal is to replace the AMD RS780+SB710 bridge chip set and provide the north-south bridge function for the Loongson processor. It was released in February 2018 and is currently used on a high-performance network platform with Loongson 3A3000 and Ziguang 4G DDR3 memory. Compared with the 3A3000+780e platform, the overall performance of the solution has been greatly improved, and it has the characteristics of high production rate, high performance, and high reliability.
