C++ MemPool for real-time systems version 1.09
Author: Amine Moulay Ramdane
Description:
Real-Time Memory Management
In C++, memory management is normally performed using new,delete etc. The run-time system's heap offers great flexibility and efficiency, but it cannot fulfil real-time requirements. The run-time requirements are non-deterministic. In addition, they may require blocking task switches, which makes them unusable for interrupt handlers.
MemPool uses templates and offers memory management with real-time capabilities through Memory Pools. A Memory Pool is an isolated heap with data buffers as objects of equal size. Any number of memory pools can exist simultaneously. A pool is initialized once and allocated a certain number of buffers as objects. Thereafter, buffers as objects can be allocated and deallocated from the pool under real-time conditions.
How to use it?
The parameters of the constructor are:
The first parameter is the number of items and the second parameter is a boolean parameter that will tell MemPool to grow or not, if it is set to true it will grow, set it to false for real-time systems, if you don't pass any parameter, the number of items will be set to 100 and the MemPool will not grow and thus it will be set for real-time systems.
The New() method returns a reference to the object, it's in O(1) time complexity.
The Return() method returns the reference to the object to the stack, it's in O(1) time complexity.
Please look at the test.cpp example to learn how to use MemPool.
