The digital possibilities are endless, as pointed out by International Collaborative Partner (ICP), UTAR Global Research Network Dr Yap Vooi Voon at the “Building a CPU-less Computer System” talk, organised on 8 November 2023 at UTAR Kampar Campus. The talk aimed to enhance participants’ knowledge in the field of computer architecture.

Dr Yap explained the fundamental concepts of computer architecture to the participants, and said, “By grasping these architectural principles, individuals can construct computer systems of varying complexities. An illustrative instance of a straightforward CPU-less system is the SAP-1, crafted by Ben Eater and detailed in the book ‘Digital Computer Electronics’ by Albert Paul Malvino and Jerald A. Brown.”

He further explained, “The SAP-1, tailored for educational purposes, stands as an exemplary model in the book, showcasing the application of digital electronics to build and analyse intricate logical systems with digital electronics. An additional illustration of a straightforward computer system is the Minimal CPU System, designed by Carsten Herting (SLU4). Drawing inspiration from some principles in Ben Eater's 8-bit computer, this system was presented through a demonstration to showcase its capabilities.” Dr Yap also generously gifted three PCB boards and encouraged interested participants to delve into its exploration, as well as to understand and build their own system.

Dr Yap, the former dean of the Faculty of Engineering and Green Technology, is retired after working 13 years in UTAR. He is also a Visiting Senior Fellowship of Aberystwyth University, United Kingdom (UK), and a Chartered Engineer (CEng), UK. He is also a Fellow of the Institution of Engineering and Technology (FIET), UK. He has more than 35 years of teaching experience and research, locally and internationally, with universities in the UK, Germany, Taiwan and other institutions.
