A predication technique for out-of-order instruction processing provides efficient out-of-order execution with low hardware overhead. A special op-code demarks unified regions of program code that contain predicated instructions that depend on the resolution of a condition. Field(s) or operand(s) associated with the special op-code indicate the number of instructions that follow the op-code and also contain an indication of the association of each instruction with its corresponding conditional path. Each conditional register write in a region has a corresponding register write for each conditional path, with additional register writes inserted by the compiler if symmetry is not already present, forming a coupled set of register writes. Therefore, a unified instruction stream can be decoded and dispatched with the register writes all associated with the same re-name resource, and the conditional register write is resolved by executing the particular instruction specified by the resolved condition.

The invention belongs to the technical field of road traffic detection and particularly discloses an expressway road traffic state estimation method based on a dynamic Bayesian network; the method comprises the following steps: (1) extracting relevant parameters of the road traffic state as nodes; (2) determining an interrelationship among the nodes and establishing the dynamic Bayesian network; (3) carrying out a fuzzy classification on data of the observable nodes, analyzing the historical data to obtain a clustering center of each classification and determining a membership degree of the data of the observable data, belonging to each classification; 4) for a target node selected in the dynamic Bayesian network, acquiring a corresponding conditional probability and a transition probability and establishing each moment characteristic table of the selected target node; 5) inputting road traffic flow parameters of the current moment to the dynamic Bayesian network and triggering to reason a target of each moment to obtain a traffic state estimation result. According to the expressway road traffic state estimation method disclosed by the invention, the uncertainty in a single parameter estimation state is solved and simultaneously the relevance in the traffic state is considered, so that better effect and reliability when the road traffic state is estimated are achieved.
