Loongson 2E

Loongson 2E is the latest processor in Loongson 2 Family. Loongson 2E was designed by ICT (Institute of Computing Technology), a department of The Chinese Academy of Sciences, helped and manufactured by STMicroelectronics.

This processor is a design of MIPSIII RISC cpu, which has separate 64KB L1 data and instruction caches. Like R10000 Family, it is also a superscalar with out-of-order execution. With On-chip 512KB L2 cache ,fast FPU and a DDR controller the processor runs at 600MHz - 800MHz.

The following 2F is under manufacture(July,2007) which has a higher frequence, an on-chip DDR2 controller and advanced power control technology.
