3DNow!
AMD's 3DNow! technology was first presented as an alternative to Intel's SSE instructions in CPUs. 3D Now!, Enhanced 3D Now!, and Professional 3D Now! was the three generations (which added full support for SSE). In August 2010, AMD revealed that future chips will no longer support 3D Now!-specific commands.
Dynamic Execution
Dynamic execution, which was first employed in the P6 (or sixth-generation) CPUs, allows the processor to execute multiple instructions in parallel, allowing tasks to be performed faster. This technological advancement is made up of three primary components:
Multiple branch prediction: predicts the program's progress via a number of branches.
Dataflow analysis: Calculates when instructions should be executed, regardless of their sequence in the original program.
Speculative Execution: Improves the pace of execution by predicting the program counter and executing instructions that are likely to be required.
Branch Prediction
Branch prediction was previously only available on high-end mainframe CPUs. It allows the processor to execute at a fast rate of speed while keeping the instruction pipeline filled. A highly efficient branch-prediction algorithm is used by a particular fetch/decode unit in the processor to forecast the path and conclusion of the instructions being executed across many levels of branches, calls, and returns. It's like a chess player planning numerous plans ahead of time by guessing the opponent's approach many moves ahead of time. The instructions can be executed immediately by anticipating the outcome of the instructions in advance.
