Abstract

Three techniques are described in providing the control structure of hierarchical top-down design. Discussed first is the linking of component control modules, second the design of a control interface for high level logic design, and third the functional partitioning of the control logic in a bus-to-bus translator. Component control modules are linked together in a hierarchical organization to allow for the application of algorithm state machines (ASMs) to functions that are not totally made up of mutually exclusive events. The method is effective in systems that have a multiplicity of mutually asynchronous functions. This is done by linking the control modules in a hierarchical organization, as shown in Fig. 1. An example of the described technique is shown by following the implementation.
