Detailed Description

Dynamic memory allocation per large block.

This file defines functions that allocate memories per a certain big block instead of allocating for each required sizes. This function will improve the overhead of memory management operation, especially when an application requires huge number of small segments to be allocated. These functions are mainly used for allocating memory for acoustic models and language models.
