;; AMD Athlon Scheduling
;;
;; The Athlon does contain three pipelined FP units, three integer units and
;; three address generation units.
;;
;; The predecode logic is determining boundaries of instructions in the 64
;; byte cache line. So the cache line straddling problem of K6 might be issue
;; here as well, but it is not noted in the documentation.
;;
;; Three DirectPath instructions decoders and only one VectorPath decoder
;; is available. They can decode three DirectPath instructions or one VectorPath
;; instruction per cycle.
;; Decoded macro instructions are then passed to 72 entry instruction control
;; unit, that passes
;; it to the specialized integer (18 entry) and fp (36 entry) schedulers.
;;
;; The load/store queue unit is not attached to the schedulers but
;; communicates with all the execution units separately instead.
