12 Questions
Which component of a CPU is responsible for performing arithmetic and logical operations?
Arithmetic Logic Unit (ALU)
In the AVR architecture, what size are the registers in the register file?
8-bit
What type of operations is the Status Register used for in the AVR architecture?
Flag Operations
Which part of the CPU architecture is primarily responsible for changing the program flow based on conditional statements?
Status Register
Which type of addressing mode involves the register X, Y, or Z containing the address of a memory location which contains the address of an operand?
Indirect addressing
In the AVR CPU, what is the significance of registers R26 to R31?
They provide 16-bit address pointers for indirect addressing of the data space
What is the function of the register X, Y, and Z in AVR CPUs?
Provide 16-bit address pointers for indirect addressing
How is indirect addressing different from direct addressing in AVR CPUs?
Direct addressing accesses memory locations directly, while indirect addressing involves accessing addresses of operands
What role does the AVR CPU play in the microcontroller?
It executes instructions and controls the operation of the microcontroller
How does the Harvard Architecture differ from the Von Neumann Architecture?
In Harvard Architecture, data and instructions are stored in separate memory units, whereas in Von Neumann they are stored together
Why is the distinction between the data bus and address bus important in microcontroller design?
The data bus size influences the 'bitness' of the CPU, while the address bus enables memory access
In what way does the 8-bit nature of the AVR CPU affect its interaction with external memory?
It limits the amount of memory that can be addressed by the microcontroller
