Can anyone suggest a good reference which explains the operation of the ALU component of the 8088 CPU? Is that design out there somewhere? Thanks! Michael
 
And what about the source code of the various PC emulators? PCE is targeted on the 5150/5160 so you don't have to filter out all the stuff meant for the 286 and better.
 
The 8086/88 also uses its ALU to perform the EA (effective address) calculations for memory operands e.g. [BX+SI+disp16] and similar; one of the enhancements NEC made in the V20 to speed it up a bit was providing a dedicated adder for EA generation.
