This paper describes a new simplistic academic CPU, designed to be constructed step-by-step by the student using a logic simulator called Logisim. An effort is made to close the gap with the real-world processors by supplying their major capabilities, like multiple programmable registers, multiple addressing modes, shift instruction, comparison and logic instructions, multiple branch and jump instructions, the stack and subroutine mechanisms, flags indicators, input/output mechanism, a proper assembler... etc. The processor would comprise 21 instructions and 4 addressing modes, with the capability using the flexible control unit sequencer, to easily add more customizable instructions.<br>

A comment by Miller was published in the August 1989 issue of Environment and Planning A, which makes an intriguing comparison of a paper by Chen and Rose with one by myself. His comment concerns the uses of various terminologies in the literature on supply-driven and demand-driven input—output models and the claims to have defined terms such as ‘stability’, ‘joint stability’, and ‘consistency’. Further, generalizations are made on the basis of a specific set of aggregated data for the US economy to show that biproportional changes suggested in my theorem are unlikely to be observed in the real world. I will show that Miller adds no illumination to the issues of ‘stability’ or ‘consistency’, and that, in fact, his comment accomplishes nothing of import. His comment could also leave us with the impression that the USA is the only ‘real-world’ example worthy of comment.

This article presents some streamlined and intentionally oversimplified ideas about educating future communication disorders professionals to use some of the most basic principles of evidence-based practice. Working from a popular five-step approach, modifications are suggested that may make the ideas more accessible, and therefore more useful, for university faculty, other supervisors, and future professionals in speech-language pathology, audiology, and related fields.
