A refinement hierarchy for free list memory allocators

Content Provider ACM Digital Library
Author Fang, Bin Sighireanu, Mihaela
Abstract Existing implementations of dynamic memory allocators (DMA) employ a large spectrum of policies and techniques. The formal specifications of these techniques are quite complicated in isolation and very complex when combined. Therefore, the formal reasoning on a specific DMA implementation is difficult for automatic tools and mostly single-use. This paper proposes a solution to this problem by providing formal models for a full class of DMA, the free list class. To obtain manageable formal reasoning and reusable formal models, we organize these models in a hierarchy ranked by refinement relations. We prove the soundness of models and refinement relations using an off-the-shelf theorem prover. We demonstrate that our hierarchy is a basis for an algorithm theory for the class of free list DMA: it abstracts various existing implementations of DMA and leads to new DMA implementations. We illustrate its application to model-based code generation, testing, run-time verification, and static analysis. .

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
