1.	Which of the following processors has a speculative execution?(a) 80486(b) P1(c) Intel Pentium(d) Pentium proThe question was posed to me during an interview.I'd like to ask this question from The Berkeley RISC Model and Digital Signal Processing in section Embedded Processors of Embedded Systems
Answer» Right option is (d) PENTIUM pro The explanation: SPECULATIVE execution is executed speculatively that is, following the predicted BRANCH paths in the code until the true path is DETERMINED. If the PROCESSOR executes correctly, then the performance is gained, if not, the results are discarded and the processor continues to execute until the correct path is identified.
