Object Coding: Strategies, Studies and Implementation

面向对象的系统表现出非常高的对象创建率，但大多数对象都是短暂的。因此，内存管理开销非常大。该项目涉及一种特定于应用程序的协处理器体系结构，以加速面向对象系统中的对象创建和内存回收。该体系结构支持位向量方法来动态分配和释放存储空间。新创建的对象驻留在引用计数的缓存中。预计大多数对象将在缓存过期之前死亡，从而显著减少对主内存的引用数量。许多现有的计算机体系结构只需要对编译器进行较小的修改就可以并入该协处理器并从中受益。

Object-oriented systems exhibit a very high rate of object creation, but most of the objects are short-lived. As a result, memory- management overhead is significant. This project is concerned with an application-specific coprocessor architecture to speed up object creation and memory reclamation in object-oriented systems. The architecture supports a bit-vector approach to dynamic storage allocation and liberation. Newly created objects reside in a cache which is reference counted. It is expected that most objects will die before they age out of the cache, drastically reducing the number of references to main memory. Many existing computer architectures would require only minor compiler modification to incorporate and benefit from this coprocessor.
