Data Hazards in Computer Architecture Quiz

Data Hazards in Pipelining

• A Read-After-Write (RAW) data hazard occurs when an instruction tries to read an operand before another instruction writes it.

Pipelining in Microprocessors

• The acronym 'RAW' in the context of data hazards stands for Read-After-Write.
• 'WAW' stands for Write-After-Write in the context of data hazards.
• One of the false statements regarding pipelining in microprocessors is not given in the text.

RISC Instruction Pipeline

• The Fetch (FE) stage in a RISC instruction pipeline fetches the next instruction from memory.
• The purpose of the Execute (EX) stage is to execute the instruction.
• The technique used to enhance CPU performance in a RISC instruction pipeline is pipelining.
• The typical stages in a RISC instruction pipeline are Fetch (FE), Decode (DE), Execute (EX), Memory (MEM), and Write Back (WB).
• The purpose of the Memory (MEM) stage is to access memory, either to load data or to store results.
