Functions

void acpu_power_on(void)

Power on ACPU, no need to be called by user

void acpu_power_off(void)

Power off ACPU, no need to be called by user

void *acpu_run_task(uint8_t task_name, void *param, uint32_t param_size, uint8_t *error_code)

Call ACPU to run specified task

Parameters:

  • task_name – [in] task name, 0 is invalid task name, any number greater than 0 is a valid task name, e.g. macro ACPU_TASK_0 defined above use 1 as the value

  • param – [in] parameter buffer pointer, the param content is copied to shared buffer which would be read by ACPU, the param buffer format is defined by each task

  • param_size – [in] parameter buffer size, max size is limited by ACPU_TASK_INPUT_PARAM_SIZE

  • error_code – [out] error code pointer, it’s used to save error code returned by ACPU, 0 means no error happens, other value means some error happens

Returns:

ACPU returned result buffer pointer, its length is limited by ACPU_TASK_OUTPUT_VAL_SIZE. buffer format is defined by each task.

void acpu_main(uint8_t task_name, void *param)

ACPU entry function

User needs to implement this function to provide customized ACPU functionality.

Parameters:

  • task_name – [in] task name, 0 is invalid task name, any number greater than 0 is a valid task name, e.g. macro ACPU_TASK_0 defined above use 1 as the value

  • param – [in] parameter given by HCPU

void acpu_send_result(uint32_t err_code, uint32_t ret_value)

ACPU send result to HCPU

It can be called by ACPU to return task result to HCPU

Parameters:

  • err_code – [in] error code needs to be sent to HCPU.

  • ret_value – [in] return value needs to be sent to HCPU.
