Fetch target buffer
Webprediction architecture and the instruction fetch unit, and it provides a glimpse at the future fetch stream of the processor. The ability of the FTQ to tolerate latency between the branch prediction architecture and instruction cache enables a multilevel branch predictor hierarchy called the Fetch Target Buffer (FTB) [14].
