What is the function of the ALU of the microcontroller? Answer: The Arithmetic Logic Unit (ALU) in a microcontroller, such as the MCS-51 series, is a crucial component responsible for performing mathematical and logical operations. It can handle basic operations like AND, OR, XOR, rotation, complement, and clear on 8-bit data. In addition to these, it also supports more complex operations such as addition, subtraction, multiplication, and division. This makes the ALU a powerful tool for processing data efficiently within the microcontroller. What is the function of the ACC of the microcontroller? A: The Accumulator (ACC) in a microcontroller is an 8-bit register primarily used to store intermediate results during arithmetic and logical operations. While it functions similarly to general-purpose registers in other microcomputers, the ACC has a unique feature in that it includes a carry flag (CY), which is essential for bit-level operations in Boolean processing. This makes the ACC particularly useful when dealing with bitwise manipulations and control logic in embedded systems.
