367 | Loongson-2 is a family of single-core CPUs and Loongson-3 is a |
368 | family of multi-core CPUs. They are both 64-bit general-purpose | |
369 | MIPS-compatible CPUs. Loongson-2/3 are developed by the Institute | |
370 | of Computing Technology (ICT), Chinese Academy of Sciences (CAS) | |
371 | in the People's Republic of China. The chief architect is Professor | |
372 | Weiwu Hu. | |

2802 | The Extended Industry Standard Architecture (EISA) bus was | |
2803 | developed as an open alternative to the IBM MicroChannel bus. | |
