This paper uses Hades, a generic processor architecture aimed at single and multiple-instruction-issue asynchronous implementations, to illustrate some of the difficulties encountered in asynchronous processor design. Particular emphasis is placed on a decoupled operand forwarding mechanism which allows the last result of each functional unit to be forwarded to following instructions, yet completely separates forwarding from the register writeback operation
