Conservative Multi-Generational Age-Based Garbage Collection with Fast Allocation

Abstract

In the era of today’s technology, Garbage Collectors have high mortality and high efficiency because they look and remove garbage memory blocks among newly created objects. Many very newly created objects are included into these objects which are still live and easily can be identified as live objects. Generational Garbage Collection is a technique which is based on newer objects where the older objects are pointed by these newly created objects; because of this, these type of algorithms earn more efficiency than other garbage collectors. The only one way called “Store Operation” is used to a formerly created objects for pointing to a newly created objects and many languages have limitations for these operations. Recently allocated objects are focused more by a Garbage Collector and these objects can give more support to the above mentioned issue. The efficiency of such type of Garbage Collectors can be measured on the basis of allocation and expenditure type than the disposal of objects. In this paper, we have studied various techniques based on Generational Garbage Collection to observe object structures for producing better layout for finding live objects, in which objects with high temporal weakness are placed next to each other, so that they are likely to locate in the same generation block. This paper presents a low-overhead version of a new Garbage Collection technique, called Conservative multi-generational age-based algorithm which is simple and more efficient with fast allocation, suitable to implement for many object oriented languages. Conservative multi-generational age-based algorithm is compatible with high performance for the many managed object oriented languages.
