Embodiment Construction
[0039] Such as figure 1 As shown, a combinatorial logic optimization method in high-level synthesis, the method includes:
[0040] A. Obtain the high-level functional description of the circuit design, and then obtain the various operations contained in the circuit design and the data dependencies between each operation;
[0041] C. Optimize the combinatorial logic operations with data dependencies, perform lookup table mapping according to the optimized results, and then build a lookup table operation network;
[0042] D. Use the constructed lookup table operation network to replace the combinational logic operations with data dependencies, so as to realize the reconstruction of operations.
[0043] According to different actual conditions, the lookup table operation network includes one lookup table operation, or the lookup table operation network includes more than two lookup table operations.
[0044] Further as a preferred embodiment, the step D includes:
[0045] D1. ...
