"WebWe propose several modifications to the binary buddy system for managing dynamic allocation of memory blocks whose sizes are powers of two. The standard buddy system allocates and deallocates blocks in \(\Theta(\lg n)\) time in the worst case (and on an amortized basis), where n is the size of the memory. We present three schemes that … " - Binary buddy algorithm

Binary buddy algorithm

The buddy memory allocation technique is a memory allocation algorithm that divides memory into partitions to try to satisfy a memory request as suitably as possible. This system makes use of splitting memory into halves to try to give a best fit. According to Donald Knuth, the buddy system was invented in … See more There are various forms of the buddy system; those in which each block is subdivided into two smaller blocks are the simplest and most common variety. Every memory block in this system has an order, where the order is … See more In comparison to other simpler techniques such as dynamic allocation, the buddy memory system has little external fragmentation, and allows for compaction of memory with little … See more • Memory pool • Stack-based memory allocation • Fibonacci number See more WebThe buddy memory allocation system is achieved using a binary tree for representing used or unused split memory blocks.
