Sunway (processor)

ShenWei (Chinese:申威), also known as Sunway, is a series of microprocessors developed by Jiāngnán Computing Lab (江南计算技术研究所) in Wuxi, China.

ShenWei SW1600 microprocessor

ShenWei SW1600, aka SW-3, is the third generation CPU by Jiāngnán Computing Research Lab. Operating at 1.1 GHz, it achieves 140 GFLOPS floating point performance from its 16 cores RISC architecture. The CPU is a national key collaborative laboratory project by Jiāngnán Computing Research Lab and High Performance Server & Storage Technologies. The People's Republic of China asserts its sole intellectual property rights. A little more information about the 65 nm ShenWei SW-3 multi-core CPU project can be found on official web site of High Performance Services & Storage Technologies - national key research laboratory. Some characteristics of the SW1600 core explained:

• Four-issue superscalar
• Two integer and two floating-point execution units
• 7-stage integer pipeline and 10-stage floating-point pipeline
• 43-bit virtual address and 40-bit physical address
• Up to 8 TB virtual memory and 1 TB of physical memory supported
• L1 cache: 8 KB instruction cache and 8 KB data cache
• L2 cache: 96 KB
• 128-bit system bus

With the published information, similarity with Alpha 21164A is suggested.

History of ShenWei processors

The ShenWei series of microprocessors was developed primarily for the use of the military of the People's Republic of China. The original microarchitecture is believed to be inspired by DEC Alpha.
