1. Loongson 3A CPU
The Loongson 3A3000/3B3000 is the latest upgraded product in the Loongson 3 series of processors. Based on the design of the Loongson 3A2000, the 3A3000 has undergone minor structural improvements, increasing the number of key queue items in the processor core and expanding the on-chip private/shared cache capacity, which benefits performance at the same frequency. Additionally, it has achieved a chip frequency increase under new processes, with actual measured frequencies exceeding 1.5GHz. The memory interface meets DDR3-1600 specifications, significantly enhancing overall chip performance. It also includes support for adjusting the chip substrate bias, better balancing performance and power consumption, and broadening the chip’s applicability. Furthermore, it maintains pin compatibility with the previous Loongson 3A1000/3A2000 chips, allowing for direct replacement and improved user experience through BIOS and kernel upgrades. The Loongson 3B3000 supports up to four fully associative multi-consistency interconnects based on the Loongson 3A3000.
The specifications of the Loongson 3A CPU are shown in the table below:
2. Kylin Operating System
