[004.3+681.3]: 619.67Abstract
Development of algorithms and designing of devices for their realization are the important factor of increase of productivity of computing systems. Earlier the author had been submitted algorithm of inversion of a divider and application of algorithm for performance of normalization of a vector. Then the description of devices of normalization of a vector has been given and research of their accuracy is made. The device of normalization of a vector is a component of the device of vector’s rotation. The process of accumulation of errors in calculations investigated in the device of vector’s rotation by methods of the numerical analysis. The addition younger bits allocated for restriction of growth of errors in this device on adders for a mantissa to the basic bits. As a result of investigations the attitudes of between numbers of the basic and additional bits are established.
