Device for the transformation of the appearance probability of logic vectors and for the generation of time-variable probability vector sequences

摘要

a test device for random logic circuits, such as microprocessors.it is necessary to use a system of transformation of the probability of occurrence of vectors and vector sequences to produce probabilities vary over time.;such a device has a memory or an equivalent circuit which is applied to vectors (ve1, ve2 log entry.6) with respective probabilities of occurrence, and with different or equal in respective areas of different areas, different types of output vectors (vs1) - vs2.... vsl). in this way, the probability of occurrence of a given output vector (ftl) - vs2.vsi) depends on the extent of the area of memory in which the vector is stored, i.e., the number of basic headings or bytes that covers this area.and the respective probabilities (pr1, pr2. prn) vectors (ve1, ve2 in... the corresponding addresses of the basic (m1, m2... mn) of the storage area.
