Abstract

A micro-pipeline, which consists of one-cycle and multi-cycle micro-pipeline units, is considered. Along with the purpose to design unified and independent of the micro-pipeline unit structure control circuit, a unified interpretation of the pipeline organization is proposed. This interpretation sets to foreground the write to pipeline register micro-operation. The implementation of a pipeline according to that interpretation is limited by the type of the registers, used to store the pipeline stage data, which are registers using only one edge (rising or falling). The mentioned limitation necessitates the usage of four-phase pipeline unit communication protocols. Accordingly, an asynchronous micro-pipeline and its control are designed. The control is capable of combining the two types of micro-pipeline units. The operation of the protocol is shown.
