Problem statement. The degree of implementation of informatization tools is constantly growing both in facilities of responsible applications and in unattended facilities. Areas of responsible use include those where system failure threatens people's lives, or those where unpredictable breakdowns and downtime will have severe economic consequences. Unattended facilities are systems where maintenance is carried out very rarely or there is no possibility of it at all. At the same time, the issues of ensuring the fault tolerance of specialized computers are becoming particularly relevant, since the control object can belong to several listed categories at once. The placement on board the vehicle limits the size and weight of the computer, narrows the possibilities of using monitoring equipment and ensuring fault tolerance. Additional complication of the problems occurs due to the requirements of operability in harsh
operating conditions: climatic, mechanical, under the influence of various kinds of radiation, natural and artificial interference. When using an foreign element base, there are risks associated with the lack of guarantees for the reliability or durability of the elements, as well as with the rapid change of element types, the short warranty period, the lack of a guarantee of delivery over the long life of the products, as well as other possible limitations.

The goal. The goal of research is the increasing of performance, memory capacity, reliability and fault-tolerance with decreasing size and mass of special-purpose computers based on domestic integrated circuits.

The results. The best-achieved characteristic of special-purpose computers based on domestic integrated circuits are:

clock rate up to 100 MHz,

performance up to 62,5 MIPS,

ROM up to 64 Mbyte,

RAM up to 8 Mbyte,

reliability up to 0,99956,

mass down to 0,5 kg,

size down to 131х65х68 mm (0,58 dm3).

The significance of research is providing of technological independence and operability in hard external environment of equipment for perspective systems used in critical objects.

Practical significance. Ensuring technological independence and operability in harsh operating conditions of the components of advanced systems in facilities of responsible use.
