●● The speedup of a processor is estimated using which of the following
parameters
Answer: Execution time in one and N processors
●● The five important parts of the Von Neumann Machine are:
Answer: Central Arithmetic, Central Control, Memory, Registers and I/O
●● The performance of a processor can be measured using
Answer: Clock period
Cycles per Instruction
Throughput
,* All of the above<<<<correct answer
●● Instructions can be speculatively executed using what two important
steps?
Answer: Instruction fetching & decode
Speculative fetch and Branch prediction
Branch prediction and data analysis>>>correct answer
*None of the above
●● What did Moore's law predict about the density and size of future
generation chips?
Answer: Density increases drastically and size reduces
●● What is the primary technology used in second generation
computers?
Answer: Transistors
,●● When is the execute cycle performed?
Answer: When instruction is fetched
After registers are decoded
When the opcode is in the Instruction register>>>>correct answer
When the instruction is buffered in the buffer register.
●● Chapter 1 Notes
Answer: computer architecture-refers to those attributes of a system
visible to programmer or those attributes that have a direct impact on the
logical execution of a program.
Computer Organization- refers to the operational units and their
interconnections that realize the architectural specifications. Examples
include the instruction set, the # of bits used to represent various data
types, I/O mechanisms, and techniques for addressing memory.
●● Which of the following approaches is used to handle multiple
interrupts?
, Answer: Disable interrupts and priority assignments
●● The only data register in the processor is
Answer: accumulator
●● Which of the following is a bus arbitration scheme?
Answer: both Centralized and Distributed Arbitration
●● How are data and instructions stored in the Von Neumann
architecture?
Answer: Unified read-write memory
●● Which of the following is a type of interrupt?
Answer: I/O interrupt
Program Interrupt
Hardware/power failure
All of the above >>>
●● The local bus connects which two components of the system?
Answer: Processor and cache
●● Which of the following is not a state of the instruction cycle?
