De er ikke færdige med at behandle disse spørgsmål, men de er nødvendige for at opretholde deres præstationer og effektivitet.

Typebestemmelse af Data Hazard-

TRE ARE THREE MAIN TYPE Of Data Hazards:

  • Read After Write (RAW): Occurs why n n instruction need s data that have not yet been writen by a previous instruction.
  • Write After Read (WAR): Haeks where n a write operation convens befor a reed operation has completed.
  • Write After Write (WAW): Takes place when n two instructions is contact to to the same register or memory location in n close successon.

Techniques før Handling Data Hazards

Several methods are use d to mitigata data hazards in n contecturs:

  • Forwarding: Also know n as data by passing, this technique passes data directly from on e stage to other, reducing delays.
  • Stalling: Introduktion af data om bubbles delays instruktio tio n execution untill data afhængige ar resolved.
  • Ordreing Instructions: Rearranging instruction sequences to o avoid hazards without hackingg program correctsness.
