Purpose: This example demonstrates basic DSP/BIOS memory operations by using the MEM_alloc() and MEM_free() functions. These functions are used to dynamically allocate and free memory in a DSP/BIOS memory segment that has been defined in the program's configuration. Design: This example uses a DSP/BIOS TSK object, initTsk, to perform its memory operations. The function initTask() is called when the TSK object initTsk is run. The initTask() function creates an array of pointers, each of which is assigned a block of memory that is returned by MEM_alloc(). After the memory is allocated, it is then freed via MEM_free(). It is important to note that all memory that is dynamically allocated must be freed (once it is no longer needed) by calling MEM_free(). It is the programmer's responsibility to free up dynamically allocated memory, and if this is not done properly, the program may crash due to memory leaks. Expected output: The output of this program can be seen by opening the DSP/BIOS Message Log. Once the program is run, the message log will display the string "mem_management example started." This is followed by some information about state of the memory segment SEG0 before allocation, after allocation, and after freeing. The program will print out the number of Minimum Adressable Units (MADUs) currently being used and the size of the largest free memory block. These values are printed before calls to MEM_alloc(), after calls to MEM_alloc(), and after calls to MEM_free(). Notice that after the MEM_alloc() calls, the number of MADUs available increases by 0x100 (the size of BUFSIZE * NALLOCS hexadecimal) and the size of available memory decreases by 0x100. Note also that after the calls to MEM_free(), the number of MADUs and size of free memory return to their original values.
