System designing of function-oriented processors for onboard correlation extreme navigation systems

The paper presents the results of investigating optimal realization of the conjunction algorithm, one of the main ones in the complex of algorithms of correlation extreme navigation systems using sensors of geophysical fields. The main result of the investigation is the procedure of algorithm DH-synthesis which makes it possible to synthesize rational architectures of function-oriented processors (FOP). Possible implementation of the conjunction algorithm on the basis of a two-dimensional array of processor elements in VLSI technology is described. The results of DH-synthesis as applied to FOP based on standard microprocessors are presented. The results of developing two generations of actual onboard FOPs for CENSs produced with the use of the procedure proposed are given.
