【Abstract】 Dynamic memory management is necessary for memory resource management in computer system. The existing dynamic memory management methods are inefficient, and have high cost of space and time. A dynamic memory management method using multilevel bitmap catalogue structure is proposed in the paper. A detailed description of the structure of multilevel bitmap catalogue as well as algorithms using multilevel bitmap catalogue to implement memory resource management is given. And the efficiency of the algorithms is also analyzed. Multilevel bitmap catalogue has some advantages, such as simple structure, low overhead of space and time, and so on.更多还原
