專利摘要 |
The present invention discloses a speculative lookahead processing device and method to enhance the statistical performance of datapaths. The method comprises steps: entering an input signal to at least two datapath units in a round-robin way; outputting the correct value at the Nth cycle, and acquiring the speculation value at the Mth cycle beforehand to start the succeeding computation, wherein M and N are natural numbers and M is smaller than N; comparing the speculation value with the correct value at the Nth cycle to determine whether the speculation is successful; if successful, excluding extra activities; if not successful, deleting the succeeding computation undertaken beforehand and restarting the succeeding computation with the correct value. |
