Analysis can be performed at the appropriate time. Therefore, wasteful suppression of analysis is no longer performed, and the cycle time may be shortened. Also, while parsing is suppressed, speculative parsing is performed and that data is available when parsing is resumed. Therefore, it is expected that the block analysis information generation time can be shortened.
- each function is described as being executed sequentially, but these functions may be executed in parallel.
- the speculative analysis process of step SA04 and the analysis restart process of steps SA05 and SA06 are described as being executed sequentially.
