cache memory synchronization is usually considered when DMA is involved. ESP-IDF provides an API to do memory allocation that can meet the alignment requirement from both the cache and the DMA.
- :cpp:func:`esp_dma_malloc`, this API allocates a chunk of memory that meets the alignment requirement from both the cache and the DMA.
- :cpp:func:`esp_dma_calloc`, this API allocates a chunk of memory that meets the alignment requirement from both the cache and the DMA. The initialized value in the memory is set to zero.
- :cpp:func:`esp_dma_capable_malloc`, this API allocates a chunk of memory that meets the alignment requirement from both the cache and the DMA.
- :cpp:func:`esp_dma_capable_calloc`, this API allocates a chunk of memory that meets the alignment requirement from both the cache and the DMA. The initialized value in the memory is set to zero.
You can also use :c:macro:`ESP_DMA_MALLOC_FLAG_PSRAM` to allocate from the PSRAM.
