  14. [I] TLSF Memory Allocator for Real-Time
  15. [T] TLSF is a general purpose dynamic memory allocator specifically designed
  16. [T] to meet real-time requirements:
  17. [T]
  18. [T] * Bounded Response Time. The worst-case execution time (WCET) of memory
  19. [T] allocation and deallocation has got to be known in advance and be
  20. [T] independent of application data. TLSF has a constant cost O(1).
  21. [T] * Fast. Additionally to a bounded cost, the allocator has to be efficient
  22. [T] and fast enough. TLSF executes a maximum of 168 processor instructions
  23. [T] in a x86 architecture. Depending on the compiler version and optimisation
  24. [T] flags, it can be slightly lower or higher.
  25. [T] * Efficient Memory Use. Traditionally, real-time systems run for long
  26. [T] periods of time and some (embedded applications), have strong constraints
  27. [T] of memory size. Fragmentation can have a significant impact on such
  28. [T] systems. It can increase dramatically, and degrade the system
  29. [T] performance. A way to measure this efficiency is the memory fragmentation
  30. [T] incurred by the allocator. TLSF has been tested in hundreds of different
  31. [T] loads (real-time tasks, general purpose applications, etc.) obtaining an
  32. [T] average fragmentation lower than 15 %. The maximum fragmentation measured
  33. [T] is lower than 25%.
