WebDynamic Storage Allocation TLSF Remarks / Open Questions DSA Operational Model DSA algorithm • keeps track of which blocks are in use and which are free • must provide at least two operations (malloc / free) Typical management of free memory blocks • Initially a single, large block of free memory • First allocation requests: take blocks from the initial pool WebNov 13, 2024 · On the other hand, specialized implementations of malloc (such as TLSF) might come with guarantees. Thus, depending on the implementation, the operation "allocating a buffer" should be modeled as having a different time complexity.
