Hades-towards the design of an asynchronous superscalar processor
C.J. Elston, Bruce Christianson, P.A. Findlay, Gordon B. Steven · 2002
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.
