释义 | microprocessor classification 微处理机[器]分类 There are at least four major classifications of microprocessor systems: calculators, controllers, data processors, and general-purpose computers. Controllers and calculators are the most likely candidates for single-chip CPUs. Data processors and general-purpose computers require more flexibility and are better served by a multichip system. Most microprocessors claim to be microprogrammable since they make use of ROM to store an intermediate-level program or a higher-level program. 微处理机系统至少可分成四大类: 计算器、控制器、数据处理机和通用计算机。控制器和计 算器大多选用单片CPU。数据处理机和通用计算机要求更为灵活,宜用多片系统构成。 大多数微处理机要求为可编微程序的,因为它们使用ROM来存放中间级程序或高级程序。 |
