Thread Level Speculation (TLS), also known as Speculative Multithreading, or Speculative Parallelization, is a technique to speculatively execute a section of computer code that is anticipated to be executed later in parallel with the normal execution on a separate independent thread. Such a speculative thread may need to make assumptions about the values of input variables.
Thread Level Speculation (TLS), also referred to as Speculative Multithreading or Speculative Parallelization, involves predicting and executing a part of computer code that is expected to run concurrently with the main execution on an independent thread. This speculative thread might require making inferences about input variable values.
