set_operation_cb()

void apb::pe::apb_target_b::set_operation_cb ( std::function< unsigned(payload_type &trans)> cb )

inline

Set the operation callback function.

This callback is invoked once a transaction arrives. This function is not allowed to block and returns the latency of the operation i.e. the duration until the reponse phase starts

Todo

refine API

Parameters

cb	the callback function
