Hi,I am new to TDA3x , I have noticed that the system of the tda3xx has two heap,one locates on ddr and one locates on local l2sram,

1.when I use malloc() function,how should I tell the system I want to get space on the heap in ddr or l2_sram?

2.how should I get space by memalign() function on l2_sram or ddr in tda3x?

Hi Chen,

please check the usage of Utils_memAlloc() function and also the values of "Utils_HeapId" enum used as first argument of this function (it is in vision_sdk/links_fw/src/rtos/utils_common/include/utils_mem_if.h)

Hi what about memalign() function? when dealing with fft, the input and output buffer should align on the double words boundary.So what function should I use for tda3x if I want to specify the heap of ddr or sram?

Hi Chen,

the last argument of Utils_memAlloc() is alignment (in bytes).
