Generation Scavenging

摘要: Many interactive computing environments provide automatic storage reclamation and virtual memory to ease the burden of managing storage. Unfortunately, many algorithms impede interaction with distracting pauses. Generation Scavenging is a algorithm that has no noticeable pauses, eliminates page faults for transient objects, compacts objects without resorting indirection, reclaims circular structures, in one third time traditional approaches.We have incorporated Berkeley Smalltalk(BS), our Smalltalk-80 implementation, instrumented it obtain performance data. We are also designing microprocessor hardware support Scavenging.
