Define speculative execution, Computer Engineering

Assignment Help:

Define speculative execution.

Speculative execution means that instructions are implemented before the processor is particular that they are in the correct execution sequence. As, care must be taken that no processor registers or memory locations are updated unless it is confirmed that these instructions should indeed be implemented. If the branch decision indicates or else, the instructions and all their associated data in the execution units must be purged, and the correct instruction fetched and implemented.
