WebJun 1, 2011 · Branch target prediction tries to predict the target of a branch given only the address of the branch instruction. The mechanism employed to implement this feature is called branch target buffer (BTB). To disambiguate it from other variants of BTBs, we will refer to this kind of BTB as addr-BTB.

WebThe wash buffer is usually phosphate buffered saline (PBS) or TBS buffer and an appropriate concentration of surfactant can be added, such as 0.01%~0.1% Tween-20 or Triton X-100 to reduce non-specific binding in samples. The cleaning process is very important. Generally, each wash step requires 2-5 washes with buffer. WebDec 6, 2024 · For uses like this, there is clear use for a branch target buffer. But for an instruction like 'beq', I see the necessity for a branch predictor, but not for the branch target because you already know the branch offset and of course you know the current program counter so you can easily come up with the branch destination.
