Buddy system binary tree
WebThe design of a simple hardware memory allocator is described, which allocates blocks of different lengths L = 2h = K, K-1,..., K-n in a memory according to the buddy system algorithm. The binary tree, representing the distribution of free and used blocks in memory is mapped into a set of shift registers. They are connected for end-around shifting and … WebMar 21, 2024 · A Binary tree is represented by a pointer to the topmost node (commonly known as the “root”) of the tree.
