About Intelligent Instruments from instrument Co. US The impact that the microprocessor has had on the domestic consumer is very evident, with its inclusion in washing machines, vehicle fuel control systems and home computers to name but a few (仅举几例)applications. The advent (出现)of the microprocessor has had an equally significant, though perhaps not so obviously apparent, impact on the field of instrumentation. It is therefore fitting that a section should be devoted to describing the principles of operation of microprocessors and explaining how they are included and programmed as a microcompu
