A system is provided that includes processing logic and a memory management module. The memory management module is configured to allocate a portion of memory space for a thread stack unit and to partition the thread stack unit to include a stack and a thread-local storage region. The stack is associated with a thread that is executable by the processing logic and the thread-local storage region is adapted to store data associated with the thread. The portion of memory space allocated for the thread stack unit is based on a size of the thread-local storage region that is determined when the thread is generated and a size of the stack.
