TDA4VM: Some questions of macro definition in custom layer dsp implementation.

#define SE_PARAM_WORDS ((uint32_t)SE_PARAM_SIZE / sizeof(uint32_t))
#define TIDL_NUM_BLOCKS(width, stride) (((width) / (stride)) + ((((width) - (((width) / (stride)) * (stride))) > 0U) ? 1U : 0U))

#define TIDL_SIMD_WIDTH_SHIFT        (6U) /* 2^6 = 64 8b elements in a 512b vector */
#define TIDL_SIMD_WIDTH              (1U << TIDL_SIMD_WIDTH_SHIFT)
#define TIDL_SIMD_WIDTH_RND          (TIDL_SIMD_WIDTH >> 1U)

Hi, I am reading the source code in PSDK_RTOS/tidl_j721e_08_06_00_10/ti_dl/custom/tidsp/. I am comfused with these macro definitions.

What are the meanings of SE_PARAM_WORDS, TIDL_NUM_BLOCKS, TIDL_SIMD_WIDTH_SHIFT, TIDL_SIMD_WIDTH, TIDL_SIMD_WIDTH_RND?

And What are the meanings of their default values? Is there any reference or introduction?

Thanks for answering.
