 By default, if you specify an unaligned address region, :cpp:func:`esp_cache_msync` will return an :c:macro:`ESP_ERR_INVALID_ARG` error, together with the required alignment.
 
 
-Memory Allocation Helper
-------------------------
-
-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_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.

-内存分配助手
-------------
-
-在涉及 DMA 时通常会考虑同步 cache 和内存。ESP-IDF 提供了能进行内存分配的 API，可同时满足 cache 和 DMA 的对齐要求。
-
-- :cpp:func:`esp_dma_capable_malloc`。此 API 可分配一块满足 cache 和 DMA 对齐要求的内存块。
-- :cpp:func:`esp_dma_capable_calloc`。此 API 可分配一块满足 cache 和 DMA 对齐要求的内存块，且内存中的初始化值已设置为零。
-
-也可以使用 :c:macro:`ESP_DMA_MALLOC_FLAG_PSRAM`， 从 PSRAM 中分配内存。
