A procedure for obtaining a behavioral description for the control logic of a non-linear pipeline

Much attention has been directed to different aspects of the design of pipelines [1,2,3,4]. Design of the control logic of non-linear pipelines has however, been considered as a subsidiary issue in that an RTL description for such logic can easily be obtained from a behavioral description, with the use of widely available synthesis tools. But, as the complexity of a nonlinear pipeline increases, so does the complexity of the control logic. The complexity may be to an extent that obtaining even a behavioral description for the control logic is rendered difficult. This paper focuses on further automating the development of systems consisting of non-linear or multi-function pipelines by proposing an algorithmic technique for obtaining a behavioral description for the control logic of such pipelines. A simplified C++ implementation that produces a VHDL description of the control logic is then presented to clarify the algorithm. Experimental results that reveal connections between the natur...
