2. Interface Change Description

2.1. Interface Changes

2.1.1. MI_IPU_TensorDesc_t Struct Gains Training Format Field (mi_ipu_datatype.h)

Before the change:

#define MI_IPU_HEAD_VER "v1.0.4"

typedef struct MI_IPU_TensorDesc_s
{
    ...
    MI_U32 au32Reserve[4]; // reserve
    ...
} MI_IPU_TensorDesc_t;

After the change:

#define MI_IPU_HEAD_VER "v1.0.6"

typedef struct MI_IPU_TensorDesc_s
{
    ...
    MI_IPU_ELEMENT_FORMAT eTrainingFormat;
    MI_U32 au32Reserve[3]; // reserve
    ...
} MI_IPU_TensorDesc_t;

Description: The eTrainingFormat field has been added to the struct (the header version has been upgraded from v1.0.4 to v1.0.6), which is used to query the training format of the input tensor, making it easier for applications to adapt the data layout before inference.

2.1.2. MI_HDMI_UserTiming_t Field Name Spelling Correction (mi_hdmi_datatype.h)

Before the change:

MI_HDMI_UserTiming_t stUserTimig;

After the change:

MI_HDMI_UserTiming_t stUserTiming;

Description: Fixes the spelling error in the member name of the HDMI user timing struct. Application code that uses this field must update the member name accordingly.

2.1.3. MI_VDF Removes the Unused MI_VDF_Obj_t and MI_VDF_ChnStat_t Structs (mi_vdf_datatype.h)

Before the change:

typedef struct MI_VDF_Obj_s
{
    MI_U16 u16LtX;  // Horizontal position of window left-top point
    MI_U16 u16LtY;  // Vertical position of window left-top point
    MI_U16 u16RbX;  // Horizontal position of window right-bottom point
    MI_U16 u16RbY;  // Vertical position of window right-bottom point
    MI_U16 u16ImgW; // the Width of the input image
    MI_U16 u16ImgH; // the Hight of the input image
} MI_VDF_Obj_t;

typedef struct MI_VDF_ChnStat_s
{
    ...
} MI_VDF_ChnStat_t;

After the change: Removed.

Description: Removes the unused MI_VDF_Obj_t and MI_VDF_ChnStat_t struct definitions to streamline the interface. Applications that use these two structs must be adjusted accordingly.

2.1.4. STSInput_t Struct Gains New Configuration Fields (sgs_sts_api.h)

Before the change:

typedef struct
{
    ...
} STSInput_t;

After the change:

typedef struct
{
    ...
    MI_BOOL enable_thinking;
    MI_BOOL cache_user_prefix;   // qwen3.5: cache user text before vision into prefix KV (image/video only)
    ...
} STSInput_t;

Description: The enable_thinking and cache_user_prefix configuration fields have been added to the STSInput_t struct, supporting thinking mode and multimodal prefix caching (other newly added configuration fields such as set_config are located in the STSParams_t struct).

2.1.5. MI_SYS Maximum Device Channel Count Extension (mi_sys_datatype.h)

Before the change:

#define MI_SYS_MAX_DEV_CHN_CNT      (128)

After the change:

#define MI_SYS_MAX_DEV_CHN_CNT      (130)

Description: In line with the SCL channel expansion to 128 channels and the VDEC/JPD maximum channel ID extension, the MI_SYS maximum device channel count has been increased from 128 to 130, and the upper limit of application-level channel IDs has been raised accordingly.

2.1.6. BF/SSL Algorithm Header File Version Update (AudioBfProcess.h / AudioSslProcess.h)

Before the change:

#define BF_API_VERSION             {'1','8'}
#define SSL_API_VERSION            {'1','7'}

After the change:

#define BF_API_VERSION             {'2','0'}
#define SSL_API_VERSION            {'1','8'}

Description: Updates the beamforming (BF) and sound source localization (SSL) algorithm header files, upgrading the versions to BF V2.0 and SSL V1.8. Applications that use the corresponding algorithm interfaces should follow the new header files.

2.2. New Interfaces

2.2.1. VLM API Release (sgs_vlm_api.h)

New type definitions:

typedef void* VLMPipeline_t;
typedef int (*VLMCropFunc)(const VLMImage_t *in, const VLMBox_t *box, VLMImage_t *out);

New interface:

MI_S32 ALGO_VLM_Create(VLMPipeline_t* pipeline);

MI_S32 ALGO_VLM_GetCosSimi(VLMPipeline_t pipeline, const MI_FLOAT* query,
                           MI_FLOAT* source, MI_U32 batch, MI_FLOAT* similarity);
MI_S32 ALGO_VLM_Deinit(VLMPipeline_t pipeline);
MI_S32 ALGO_VLM_Release(VLMPipeline_t pipeline);

Interface description: Adds the VLM (Vision Language Model) API header file (341 lines in total), providing a complete set of interfaces for VLM pipeline creation, initialization, inference, and similarity computation, along with the VLM prebuilt library, for multimodal AI application development.
