What is speculative execution, and how does it contribute to the vulnerability of modern processors to timing attacks like Spectre?
Wednesday, 12 June 2024 by EITCA Academy
Speculative execution is a performance optimization technique employed by modern processors to improve instruction throughput and overall computational efficiency. It involves the processor making educated guesses about the direction of future instructions and executing them in advance. This preemptive execution leverages the inherent parallelism within the processor's architecture to keep the execution units busy, reducing
