Abstract
We are defining a computer architecture to support a decentralized operating system that is under development. Since complex functions of this system could appear directly in the architecture's instruction set, we are immersed in the current RISC/CISC debate where we have found many questions and few answers. Hoping to shed light on aspects of this conflict, we have embarked on two studies. The first seeks to find an environment where complex instructions can enhance system performance. The second tries to decouple multiple register set performance from instruction set performance in general-purpose register machines.Keywords
