摘　　要：在动态内存管理方式中,伙伴系统具有管理方式简单,分配与释放速度快等优点,但伙伴系统的缺点是对内存空间的利用率比较低,在嵌入式系统中,内存管理除了应该具备管理方式简单和处理速度快等特点外,内存的利用率也十分重要。通过对伙伴系统分析,并对伙伴系统的内存利用率方面进行改进,显著提高嵌入式系统中内存的利用率。Buddy system is a good memory management method that has many merits including simple management style,and fast assign and release memory.But the utilization ratio of memory is lowly in buddy system.However,the utilization ratio of memory is very important especially for embedded system,except simple management style and fast speed of assign and release memory.This paper discussed buddy system,and utilization ratio of memory in embedded system has improved base on these discussions.
