Hello......

MemPool for realtime systems was updated...

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


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...

I mean:

The previous TStack was not making MemPool real-time, I have written
DLList.pas that contains a new DStack that makes MemPool real-time.
