The paper concerns selection of an appropriate CPU while designing a modern management-information system(MIS) with application level programming. It is shown that the traditional MIS design methodology not always provides suitable solution. In that case a new problem-oriented CPU is necessary to be created. A number of different subjects involved in the CPU design is researched: microarchitecture, instruction set architecture (ISA), instrumental tools, etc. This paper describes unique architecture of problem-oriented CPU for real-time digital signal processing named NL3 designed by LMT Ltd.
