11. Meanwhile, he continued to study computer architecture in technical manuals outside of school. 12. All computer operating systems are designed for a particular computer architecture . 13. In some aspects, it may be seen as a high-level language computer architecture . 14. Many agent-based modeling software are designed for serial von-Neumann computer architectures . 15. Goodman's research is focused mainly on computer architecture : the hardware / software interface. 16. Sussman has also worked in computer languages, in computer architecture and in VLSI design. 17. Some microassemblers are more generalized and are not targeted at a single computer architecture . 18. Specialized parallel computer architectures are sometimes used alongside traditional processors, for accelerating specific tasks. 19. Designing large, high-performance cache coherence systems is a very difficult problem in computer architecture . 20. His security, operating systems, computer architecture ( capability systems ) and local area networks.
