Selection of processor

What is the main function of a processor in an embedded system?

• To store data
• To execute program instructions
• To provide power
• To display images

Which of the following factors should be considered when selecting a processor for an embedded system?

• Power consumption
• Cost
• Processing speed
• All of the above

What is the primary difference between a microprocessor and a microcontroller?

• A microprocessor is more powerful
• A microcontroller has more input/output ports
• A microprocessor is more expensive
• A microcontroller has more memory

How does the power consumption of a processor impact the design of an embedded system?

• It determines the size of the battery
• It determines the type of power supply needed
• It determines the size and weight of the device
• It determines the operating temperature range

What is the role of clock frequency in the performance of a processor in an embedded system?

• It determines the amount of memory needed
• It determines the number of input/output ports needed
• It determines the processing speed
• It determines the type of power supply needed

What is the significance of cache memory in a processor?

• It stores frequently accessed data and reduces access time to main memory
• It executes program instructions
• It stores all data and instructions
• It manages input/output operations

What are the advantages and disadvantages of selecting a processor with a higher clock frequency for an embedded system?

• Advantage: higher processing speed, Disadvantage: higher power consumption
• Advantage: lower power consumption, Disadvantage: lower processing speed
