Computer architecture has been and will always significantly influenced by the underlying trends and capability of hardware and software technologies. Current computer architecture research maintains a bias for the past in focuses to desktop and server application. A distinct computer area, personal mobile computing, will, in my opinion, play a major role in propelling technology in the coming decade. This area will have its own set of needs for microprocessors, which may shift the focus of

... uter architecture. The evolution of computer architecture from electromechanical relays through vacuum tubes to transistors to integrated circuits has resulted in fundamentally different trade-offs. Additional software advancements include the shift in programming paradigms from machine code to assembly language to high-level procedural language to object-oriented language. The impact on these technology on computer system architecture in past and in future will be explored and projected in future.
