微型机的应用日趋广泛。市场上的微机产品多种多样,性能各异,适用范围也不同,那么,怎样选择微型机呢?一、适用性。根据用途需要,量“用”选机,做到“适用”(即能满足需要)而又“有效”(即充分发挥微机功能),不要盲目追求高性能、高指标,避免浪费。用途功能一般以占微机功能的70%比较适宜,以便将来扩充使用。根据不同用途选择不同性能的微机,主要从体系结构、字长、存储容量、芯片、外设配置,系统软件诸方面进行选择。
Microcomputer applications are becoming more widespread. A variety of computer products on the market, different performance, the scope of application is different, then, how to choose the micro-it? First, applicability. According to the needs of use, the amount of “use” election machine, so that “applicable ” (that is, to meet the needs) and “effective ” (that is, give full play to computer functions), do not blindly pursue high performance, Prevent wastage. Use functions generally account for 70% of computer functions more appropriate for future expansion. According to different uses to choose different performance of the computer, mainly from the architecture, word length, storage capacity, chips, peripherals configuration, system software and other aspects of choice.
