WebThe buddy algorithm maintains free lists of different sized blocks. When a request for memory is made these free lists are searched. If the appropriate size is not found a larger block is split (variations of this algorithm determine how the block is actually split, for example, in a binary buddy system the block is split by powers of two). WebIn the binary buddy system, each block has exactly one buddy, the identity of which can be determined directly from the address and size of that block. At the start, all of memory, or …
