Algorithmic Design and Implementation of A Three-Operand Leading-one Prediction Error-Correcting Code Module

In this paper, we propose an error correction scheme based on the prediction error of the three operation number prediction algorithm. According to the process of leading-one prediction and pre-encoding rules, designing a error-correcting module pre-encoding, and completing the overall structure of the error-correcting module, using hardware description language VHDL to program some function module to optimize the design process, and use QuartusⅡ tools to perform comprehensive validation, received the RTL-level hardware circuits, and last the results are analyzed and verified. Simulation results show that the designed algorithm structure can effectively complete the Leading-one prediction correcting function.
