CAMA: Cache-Aware Memory Allocation for WCET Analysis

Webwas greatly inﬂuenced by TLSF. In fact, it can be regarded as a cache-conscious modiﬁcation of TLSF. Chilimbi et al. proposed a cache-conscious memory allocator (ccmalloc) in order to improve program execution times [2]. Compared to malloc, Chilimbi’s ccmalloc takes as an additional argument a pointer to an WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
