HEAP MEMORY MANAGEMENT RTOS

What is heap memory in an RTOS system?

• A region of memory that is reserved for the RTOS kernel

• A region of memory that is allocated dynamically at runtime

• A region of memory that is used for storing the stack of RTOS tasks

• A region of memory that is used for storing global variables

What is the purpose of a memory heap in an RTOS system?

• To provide a region of memory for the RTOS kernel

• To provide a region of memory for global variables

• To provide a region of memory for the stack of RTOS tasks

• To allow for dynamic allocation and deallocation of memory during runtime

Which of the following RTOS memory allocation functions should be used to allocate memory from the heap?

• malloc()

• free()

• realloc()

• calloc()

What happens if an RTOS task tries to allocate memory from the heap, but there is not enough free memory available?

• The task will be suspended until enough memory becomes available

• The RTOS kernel will automatically increase the size of the heap

• The system will generate an error and terminate execution

• The task will be given a lower priority and put on hold until enough memory becomes available

How does an RTOS system prevent heap memory fragmentation?

• By defragmenting the heap periodically

• By compacting the heap periodically

• By using a memory pool instead of a heap

• By limiting the size of dynamic memory allocations

What is the function of the RTOS memory heap management module?

• To allocate memory to the RTOS kernel

• To manage dynamic memory allocation and deallocation

• To manage the stack of RTOS tasks

• To manage global variable allocation and deallocation

Which of the following is a potential issue with dynamic memory allocation in an RTOS system?

• Heap fragmentation

• Heap overflow

• Memory leaks

• All of the above

What is the benefit of using a memory pool instead of a heap in an RTOS system?

• Reduced risk of heap fragmentation

• More efficient use of memory

• Faster memory allocation and deallocation

• All of the above

Which of the following is true about the heap_4.c implementation in FreeRTOS?

• It uses a best-fit algorithm to allocate memory blocks

• It is designed to be complex and resource-intensive

• It is suitable for embedded systems with limited resources

• It cannot be used in conjunction with other memory allocation schemes

In FreeRTOS, where is the heap size typically configured?

• In a separate configuration file

• In the source code of the application

• In the FreeRTOS kernel initialization function

• In FreeRTOSConfig.h using the configTOTAL_HEAP_SIZE parameter
