Real-Time Design Patterns: Robust Scalable Architecture for Real-Time Systems

Chapter 6. Memory Patterns

The following patterns are presented in this chapter.

• Static Allocation Pattern: Allocates memory up front

• Pool Allocation Pattern: Preallocates pools of needed objects

• Fixed Sized Buffer Pattern: Allocates memory in same-sized blocks

• Smart Pointer Pattern: Makes pointers reliable

• Garbage Collection Pattern: Automatically reclaims lost memory

• Garbage Compactor Pattern: Automatically defragments and reclaims memory

Memory Management Patterns

Much of the difficulty in building complex real-time and embedded system centers around managing shared resources in ways that are simultaneously efficient and robust. The patterns in this chapter focus on efficient management of memory as a resource and the robust sharing of general software ...
