Detailed Description

Function Documentation

__attribute__()

struct csinn_session * __attribute__

(

(weak)

)

Import binary model.

Returns

Load the completed session structure when successful.

For the interface of hhb model, it is a further encapsulation of csinn_load_binary_model, defined as a weak function, and can be covered by a user-defined function with the same name.

csinn_alloc_session()

struct csinn_session * csinn_alloc_session

(

)

Allocate a session.

Returns

Point to the newly allocated session csinn_session*

This interface only allocates memory space. Initialization is performed by csinn_session_init complete. Each session refers to an instance of a model.

csinn_free_session()

void csinn_free_session

(

struct csinn_session *

session

)

Release a session.

Parameters

[in]

session

The session to be released

csinn_session_init()

void csinn_session_init

(

struct csinn_session *

session

)

Initialize session.

Parameters

[in,out]

session

The session to be initialized

Board specific initialization can be done in the interface, such as calling some initialization function interfaces of NPU.

csinn_session_deinit()

void csinn_session_deinit

(

struct csinn_session *

session

)

Uninitialize session.

Parameters

[in,out]

session

The session to be uninitialized

csinn_session_setup()

int csinn_session_setup

(

struct csinn_session *

session

)

Setup function.

Parameters

[in]

session

The session to be processed

Returns

The return value is greater than 0 on success

Build the interface of the graph when executing according to the graph. For example, you can call the compilation interface in the NPU driver here.

csinn_session_run()

int csinn_session_run

(

struct csinn_session *

session

)

Run function.

Parameters

[in]

session

The session to be executed

Returns

The return value is greater than 0 on success

When executing according to the graph, actually implement the interface of the graph.

csinn_load_binary_model()

int csinn_load_binary_model

(

struct csinn_session *

session

)

Load binary model.

Parameters

[in]

session

The session to be executed

Returns

The return value is greater than 0 on success

There is no need to call csinn_session_setup when model binary execution is adopted.
