BIU (Bus Interface Unit) manages the microprocessor's communication with external devices, handling operations such as reading data from input devices or writing data to output devices. The EU (Execution Unit) is responsible for executing the instructions fetched by the CPU. It performs arithmetic and logic operations, handles branches, and manages the flags (like carry, zero, sign, auxiliary carry, parity, and overflow).
