#3646 — MemPool for realtime systems was updated again...

Hello,

MemPool for realtime systems was updated again...

The previous TStack was not real-time, I have written a Stack.pas that 
is a bounded stack that makes MemPool real-time, and i have enhanced 
MemPool too.


Description:

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.

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.

And please look at test.pas demo inside the zipfile - compile and 
execute it...
