#3642 — MemPool for realtime systems is here...

Hello...

MemPool for realtime systems is here...

Real-Time Memory Management

In Delphi and FreePascal, memory management is normally performed using 
getmem,allocmem, freemem, reallocmem,  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.

My following MemPool that uses generics 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.

You can use it with Delphi 2009 and up on the following RTOS:

Win32 API Compatible RTOS for 32/64-bit x86 Embedded Systems

On Time's royalty-free hard real-time embedded operating system for 
32/64-bit x86 CPUs implements a Windows subset kernel in only 16k of 
memory. It provides about 400 Win32 API functions and can load Windows DLLs.

I will soon port my Threadpool engine so that you will be able to
do realtime system programming with it.

You can download MemPool from here:

Hello,

TStack was not real-time, I have written DLList.pas that contains a new 
DStack that is real-time.

Please download it again the updated version of MemPool:
