"The Advance Dynamic Execution engine is a very deep, out-of-order speculative execution engine that keeps the execution units executing instructions. The Pentium 4 processor can also view 126 instructions in flight and handle up to 48 loads and 24 stores in the pipeline. It also includes an enhanced branch prediction algorithm that has the net effect of reducing the number of branch mis-predictions by about 33% over the previous P6 generation processor's branch prediction capability. It does this by implementing a 4-KB branch target buffer that stores more detail on the history of past branches, as well as implementing a more advanced branch prediction algorithm."
OK.

ezt pontosan hol találtad?
Ez ellentéts azzal, amiket eddig olvastam, szeretném átnézni az anyagot, mert ez érdekel.
előre is thx.
