- MemPool for realtime systems is here... - 1 Update
| Ramine <toto@toto.net>: Mar 03 06:48PM -0500 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.
