1. A pipelined system having an upstream end and a downstream end, the pipelined system comprising: (a) a downstream positioned execution unit for receiving microinstructions and one or more operands, time-aligned to corresponding ones of the microinstructions, for immediate execution in said execution unit; (b) an operand-storing unit for storing operands to be executed by the execution unit; (c) an upstream positioned fetch unit for initiating the fetching of operands from the operand-storing unit; (d) delivery means having an upstream end coupled to the upstream positioned fetch unit and a downstream end coupled to the downstream positioned execution unit for conveying operands fetched by the fetch unit to the execution unit; (e) side-track storage means, having an input end and an output end positioned downstream of the input end, for temporarily storing operands delivered to the input end and subsequently outputting the delivered operands from the output end, thereby sidetracking the operands delivered to the input end; (f) copying means, coupled to an upstream portion of the delivery means, for copying operands moving through the upstream portion of the delivery means into the input end of the side-track storage means so as to create side-tracked copies of said operands; and (g) deposit means for depositing side-tracked copies of premature operands that would have otherwise arrived at the execution unit prematurely, before the execution unit is instructed to process such premature operands, into either a downstream portion of the delivery means or directly into the downstream positioned execution unit such that the deposited copies arrive in the execution unit in time-alignment with the corresponding microinstructions that instruct the execution unit to process the deposited copies.
