The main concepts of a new HLL computer "CAMCOH"

The concepts of a new computer and the peculiarities of its architecture are discussed. A new industrial technology of creating complicated embedded systems was elaborated in Sankt-Petersburg university in collaboration with some industrial institutes; it was successfully used in several large projects (electronic telephone stations, network control, etc.). The main idea of this technology is using fixed high level algorithmic language (HLL) through all life cycle stages beginning with requirements and specification to translation to the target computer codes and maintenance. It was shown that any HLL is not fit enough for successful use as a basic language. For technology purpose the best are languages of static type (i.e. with full mode checking in compile time), e.g., Algol 68, Ada, Modula 2. Habitually in embedded systems specialized computers are applied which are possible to use in extreme situations. But it is only very rare that such a computer has an involved operating system, disks and displays or HLL compilers. That is why large software projects are to be worked out using powerful tool (host) computers and cross-compilers. than 15 compilers and cross-compilers were implemented, best of which provide the coefficient of object code enlarging in compare with hand written programs less than 1.4. The implementation of a compiler, however, is very sophisticated problem and even a small loss of 1.4 times is often unfit for limited resources of specialized computers.
