"ALU class"?
Googling gives me no clue.
4th hit: Arithmetic Logic Unit (hardware) -- Wikipedia
ALU class -- software version or simulation thereof.
The hardware version of Dennis's distributed design would be
interesting. Spreadsheets are based in part on the same idea of
distributed logic and arithmetic.
