Explanation

The Execution Unit (EU) in microprocessor architecture contains the Arithmetic Logic Unit (ALU) for computations, general-purpose registers for data manipulation, and flag registers to store condition codes and status information. The clock generator is part of the Bus Interface Unit (BIU), not the EU - it provides timing signals for the entire processor.
