Problem Set 8 Flashcards
Which status flag listed below activates or set to “0” if a result of an operation is either a positive or a negative number?
Negative flag
What is the reason why assembly language programmers makes use of the general purpose registers rather than main memory?
registers can transfer data faster than main memory
Which element if a modern CPU is responsible for processing op-codes and converting the to uOps?
Instruction decoder
CCR stand for
Condition Code Register
Which of the following execution units is primarily tasked to perform basic addition, subtraction, multiplication, and division on floating point numbers?
Floating Point
In which pipeline stage does the microprocessor reads an instruction or command from a program stored in the main memory and copies the op-codes to the instruction register?
Fetch
Which of the registers given below can be classified as an address register, since it also holds a memory address?
Index register
Which of the following x86 instruction set extension added streaming single-instruction with multiple-data functionality to INTEL microprocessors?
SSE or Streaming SIMD Extensions
The main purpose of this register is to accumulate data being processed by the ALU of the microprocessor.
Accumulator
In the processing units that calculated addresses used by the CPU, what does the acronym AGU stand for.
Address Generation Unit

Which type of register is used to determine and identify the location of a specific data in the system memory?
Address register
This is the taken condition when a CPU executes a new instruction with a branch, without knowing if that branch has been taken or not.
speculative execution
