Abstract: A program controlled integrated circuit having an input path for receiving an analog signal with given attributes and using a program controlled sequence of treatment stages to generate a bit-defined information vector. That vector is introduced to a distributed memory matching array where it is compared with conveyed instruction set having bit-defned codewords corresponding with an analog signal attribute. A match process under the control of a central control unit then develops a digital result. The digital result may be utilized or converted to analog form in an analog return path. Both the input path and the return path incorporate a reduced instruction set computing arithmetic unit under the control of the central control unit.
