Programming

• Programming of system and scientific software with different programming languages satisfying different goals:
  • Imperative languages like C for lowlevel system programming and Fortran for solving of pure mathematic problems.

  • modern functional programming languages of the ML family for abstract and some kind of safety highlevel programming.

  • use of virtual machines as a portable and operating system independent program execution environment.

• Programming and Synthesis of digital Logic:
  
  
  • Low integrated programmable logic components like CPLDs for efficient and flexible implemenations of simple combinatorial logic problems.

  • High integrated programmable components like FPGAs for more complex combinatorial and sequentiel logic, mostly state machines for microcontroller similar execution of more complex problems.

  • Use of VHDL (VHSIC (Very High Speed Integrated Circuits) Hardware Description language) and Verilog-HDL as programming and hardware description languages.
