FreeRTOS Heap Management Quiz

Which of the following heap_x.c mechanisms in FreeRTOS allows for dynamic memory allocation but does not permit memory to be freed?

• heap_1.c

• heap_2.c

• heap_3.c

• heap_4.c

What is a key feature of the heap_4.c mechanism in FreeRTOS?

• Memory cannot be freed

• Coalesces adjacent free blocks to reduce fragmentation

• Uses standard library functions for memory management

• Allocates memory from multiple non-contiguous regions

In the heap_2.c mechanism, what is a major drawback?

• It does not support freeing of memory

• Memory fragmentation is not handled

• Only allows memory allocation in fixed sizes

• It uses the system's standard memory functions

In which FreeRTOS heap management mechanism must the vPortDefineHeapRegions() function be called to define memory regions?

• heap_1.c

• heap_2.c

• heap_4.c

• heap_5.c

What is the advantage of using heap_3.c in FreeRTOS?

• It reduces memory fragmentation

• It uses the standard malloc() and free() functions

• It coalesces adjacent free blocks

• It allows for multiple non-contiguous memory regions

Which of the following is true about heap_5.c in FreeRTOS?

• Memory allocation is done using a fixed-size block approach

• It only supports contiguous memory allocation

• It can allocate memory from multiple, separated memory regions

• It does not allow freeing of allocated memory

What is the primary goal of heap_4.c in FreeRTOS?

• Use standard library functions for allocation

• Provide fixed-size allocation for tasks

• Minimize memory fragmentation through dynamic allocation

• Allow memory allocation without freeing

Which mechanism would be ideal in FreeRTOS for systems with multiple memory regions?

• heap_1.c

• heap_2.c

• heap_4.c

• heap_5.c

Which FreeRTOS heap management mechanism uses a best-fit algorithm for memory allocation?

• heap_2.c

• heap_3.c

• heap_4.c

• heap_5.c

What is a characteristic of heap_1.c in FreeRTOS?

• It allows memory to be freed and reallocated

• Memory is allocated but cannot be freed

• Uses a best-fit strategy for memory allocation

• Memory is allocated using standard library functions
