packed code meaning in Chinese

紧缩码

First of all , base on the kernel of embedded operation system , embedded file system must improve the efficiency of data input / out to match the real - time requirement of embedded system while using the services supplied by kernel . secondly , the limitation of internal memory cause that the embedded file system must possess tightly packed code and can be configured according to requirement . in other words , file system can ’ t result in any code burden and system expenses in the extreme case that the application doesn ’ t using it at all
首先,嵌入式文件系统基于实时操作系统内核,在使用内核提供的各项服务的同时,应该尽可能提高数据存取的效率,以与系统整体的实时性相匹配;其次,嵌入式系统物理内存的局限决定了嵌入式文件系统必须具备代码紧凑、按需配置的特点,在应用不使用文件系统的极端情况下,文件系统不能对系统造成任何的代码负担和开销;最后,嵌入式文件系统应该尽可能独立于硬件体系结构,因此在实现上应该具有较好的移植性。
