Advantages of Buddy System
- Easy to implement a buddy system
- Allocates block of correct size
- It is easy to merge adjacent holes
- Fast to allocate memory and de-allocating memory
- It provides optimal memory performance while allocating blocks of memory of appropriate size and prevents unnecessary memory waste, unlike other allocation techniques which allocate larger memory blocks than necessary
- It provides a flexible and efficient way to manage memory allocation in systems that require dynamic memory allocation, such as embedded systems and operating systems
- It can handle a large number of small memory allocations efficiently thanks to its block partitioning mechanism, which helps prevent fragmentation and keeps system performance up
- It can prevent memory leaks by ensuring that all shared memory is cleared when not in use, which can improve system stability and reliability
- It provides a high level of flexibility in memory allocation and monitoring processes, which is particularly useful in systems that require frequent memory allocation and sharing, such as real-time systems
Buddy System – Memory Allocation Technique
Static partition techniques are limited by having a fixed number of active processes, and space use may not be optimal. The buddy system is a memory allocation and management technique that uses power-of-two increments. Assume the memory size is 2U and a size of S is required. In this article, we are going to discuss the Buddy System in detail along with examples, advantages, disadvantages, etc.
